  • One of the most popular models in the Bulls ebike lineup, it comes in four frame sizes and three styles (high-step diamond, mid-step, and step-thru wave), motor and battery weight are low and center
  • Extremely stealthy, the drive system and battery are almost completely hidden on this frame and the motor produces very little noise because it uses a belt system inside, this reduces vibration
  • Compared to the 2017 model, the price has dropped by $200 but it uses a standard chain vs. a fancy belt drive, the internally geared hub is durable and can be shifted at standstill, the LCD display is easy to read because it's large, has a Micro-USB charging port, and is removable
  • Excellent rear rack with pannier hangers, basic integrated lights that help you be seen, decent plastic fenders that rattle a bit but won't get bent up, I like the chain cover and guide on the chainring, highly-adjustable air suspension fork

Written Review

I was told that the Lacuba EVO E8 is one of the most popular electric bike models that Bulls currently sells (for the 2017/2028 timeframe). I think that has to do with how feature rich and versatile it is… Whether you’re riding around the neighborhood for fun, going out for long weekend treks, or commuting to work on a daily basis, this platform pretty much has you covered, rain or shine. What you see in the main image and video review above is just one of the three frame style choices. The deep step-thru wave frame is meant to be approachable and comfortable but sacrifices stiffness and doesn’t look as masculine or sporty as the high-step. For those who have sensitive knees or hips and want to avoid the high-step but still want a bit of stiffness for improved handling, there’s a mid-step option! The bike is available in four frame sizes and you can select the one that fits your physical needs and ride style best. This kind of range is usually only available from the bigger European brands that sell globally, and that is the case with Bulls, they also offer a comprehensive two-year warranty and have a wide network of dealers to visit and test ride or get service from. The Lacuba EVO E8 is purpose-built with internally routed cables, a custom motor interface, and battery integration that is almost invisible from the side. Add to the beautiful visuals a motor that is super quiet and smooth, and this electric bike blends in with regular bikes almost perfectly. In the industry, people refer to this as being “stealthy” because you can fly below the radar and fit in more easily. Some of the compromises that I noticed about this ebike were cheaper “be seen” lights, and a headlight position that could bounce about vs. being suspended. A heavier, bulkier charger that fills the battery quickly but might not be as convenient to take along in a backpack. Fenders that can rattle a bit, an internally geared hub that won’t shift as quickly and adds a bit of weight compared to a cassette and derailleur, and a touch-sensitive menu button on the control pad that can be easily bumped and change your readouts by mistake (or be difficult to use if you’re wearing gloves). There are always trade-offs to consider when price and weight are a factor, and I think Bulls has done an excellent job of not only maintaining the price from 2017 but actually lowering it by $200 for 2018, by swapping the belt drive for a traditional chain. It’s still very quiet and reliable, but using a chain allowed the frame to be simpler and sturdier because they didn’t have to make a cut-out on the right seat stay to get a belt on. The only think I’d consider upgrading on this ebike, if I were buying it for myself, would be the rigid seat post. I’d probably get a 30.9 mm suspension seat post like this if I was riding frequently, just to reduce back and neck sensitivity when riding over bumps. As it stands, the highly-adjustable air suspension fork can be set to lower pressure for lightweight riders (who often suffer with stiff one-setting spring suspension), and the wider 2″ tires, swept-back handlebars, adjustable angle stem, and fatter ergonomic grips make this a very comfortable bike with upright ergonomics vs. forward.

Driving the bike is a proven Brose T mid-motor. It’s compact, exceedingly quiet, smooth, and dynamic. Some cheaper motors rely purely on pedal cadence and will only help you up to a certain pedal speed. The Brose motor cotroller, by contrast, listens for rear wheel speed, pedal cadence, and pedal torque to deliver a natural experience. It does not incorporate shift detection like Bosch and some Impulse systems, but that’s less of an issue with the internally geared hub here. The Shimano Nexus Inter8 is a mid-level part that provides a good range of pedaling options as well as some self-protection mechanisms. If you try to shift while pedaling hard (or if the motor is pushing hard), you may hear some clicking and notice that the gear does not change. As you ease off a bit and the motor slows down, the gear will click into place. This behavior is different than traditional sprockets and derailleurs that will basically force a change and compromise the chain and teeth on the sprockets, wearing them out quicker. For cyclists who have ever had their bike tip over and bend the derailleur or those who have experienced dropped chains and lots of greasy noisy operation… internally geared hubs can seem like a dream because they are so durable and clean. The chain on this bike never changes position, there’s just one chainring up front and one sprocket in the back, and Bulls opted for an alloy guide on the chainring so it’s almost impossible to have the chain fall off. To me, this is almost overkill because the Lacuba EVO E8 isn’t designed to assist you over 20 mph and is not setup for extremely bumpy off-road use. Still, it doesn’t add much weight to have the full chain guide vs. a chainring guard, so I see it as a nice little upgrade. Coming back to the motor performance briefly, this thing will assist with up to 120 RPM pedal strokes, which is the highest that any systems I have tested offer, and that means you don’t have to switch gears as frequently to go faster. If you’re willing to pedal fast, this motor is willing to support you all the way. For those who do enjoy shifting but may not be as familiar with triggers, the Shimano Nexus half-grip shifter on the right portion of the handlebar is intuitive to use and has a little window to help you see which gear has currently been selected. One of my favorite features of most internally geared hubs like this, is that they can be shifted at standstill. Imagine pedaling fast and then stopping at a traffic signal without remembering to shift down (to prepare for a low-speed start). That’s not a problem here, just shift down to the lowest gear while you’re stopped and kind of ease off the pedal to allow it to click into place, then you’re ready to go again!

Powering the bike, it’s beautiful backlit display panel, the integrated Micro-USB port at the base of the display, and both front and rear LED Lights is a high-capacity Lithium-ion battery pack from BMZ. This thing offers nearly 650 watt hours (compared to ~500 wh on most ebikes I see for 2018) and it clicks up into the downtube of the frame to be protected, low to the ground, and hidden. The first Lacuba EVO E8 model I reviewed in 2017 had a foam sticker underneath the battery pack, to keep little rocks and dirt from nicking the plastic casing. The newest design has a tougher rubber coating that protects more of the casing and blends in a lot better. The battery seats securely and can be charged on the frame, though a port on the top side of the downtube, near the locking key port. This charging port has a re-designed rubber cover that seats in well enough to keep dust and water out, and when you plug the charger in, it uses a magnetic EnergBus Rosenberger standard (RoPD) that will simply pop out if snagged vs. bending or tipping the bike. This port is actually on the battery pack itself, only a cutaway in the frame allows you to reach through, and of course, the battery can be charged when taken off of the bike too. If you decide to do this however, be careful, because the battery weighs ~1 lb more than competing packs due to the higher capacity. And, since it comes out downwards below the frame and doesn’t have an integrated handle, it can be a little awkward to get off. Avoid dropping this pack because replacements are upwards of $900. I usually remove battery packs when storing them, to avoid extreme heat, cold, and rain. I may also remove the pack to reduce weight when transporting the bike with a car rack, and this is one area where you might need to spend some additional money, to get a sturdy platform rack like this, unless you get the high-step frame and are okay lifting it higher and hanging it from the top tube. Okay, so the battery is pretty great overall, it should provide excellent range with the efficient mid-drive motor if you shift gears thoughtfully, and there’s even a range menu in the display that can help you estimate how far until a charge top-off is needed.

The LCD display panel that comes with this electric bicycle is quite good. It’s much larger, brighter, and more feature-rich than a lot of competing products… even from Bulls. I think this is because the Lacuba EVO E8 is an urban product, not a mountain bike where you want to keep the handlebars clean and streamlined in the event of a crash. This display stick way up high, is easy to see, and can be adjusted to angle directly towards you (though you cannot easily swivel it without tools once it’s locked into place). You can navigate all of the different menus without taking your left hand off the grip, just reach your thumb over to click the little button pad. Powering the bike on requires a press on the top-edge button, activating the lights uses a little top left-side button, walk mode is the lower left-side button, and then there’s a + and – main button on a sort of rocker. These are your primary touch points, more or less assistance. You can ride the bike without any assist, as was demonstrated in the video review by Tony (a random neighbor who was curios and asked to take a test ride). It’s an efficient bike, especially if you have the tire pressure set near the upper limit. From here, you can click through four different levels, designated by four boxes, to receive a 50% to 320% boost. The higher you go, the more zippy the bike will feel and the easier it will be to reach the maximum 20 mph top speed. This is a Class 1 electric bike, so there’s no throttle mode, you have to pedal, but this is the most widely allowed ebike type and is treated as a standard bicycle in most locations. And again, because the motor and battery are so hidden and quiet, people might not even notice what you’re riding. As someone with a sensitive knee, ebikes like this have allowed me to continue commuting to work and getting a healthy stretch when traditional bikes left me struggling in the wind and with larger hills. As mentioned earlier, this display can be twisted to be removed for protection when parking (or you can use the included set screw to secure it more permanently from the back) and it has a little Micro-USB port near the bottom to charge your portable electronics. If you want to explore the different menu settings, and change the units from miles to kilometers and back, you can hold the light button for a few seconds and then navigate through. There’s just one more button to talk about here, and that’s the menu button on the center of the control pad… it looks like two overlapping boxes, inside of a circle. This is a touch sensitive button that cycles through the readouts of the display and gets you to that range menu. I struggled to figure this button out at first and then fumbled with it on camera, when trying to show how range updates dynamically as you change assist levels. It’s easy to activate the menu button when trying to arrow up or down on assist and this is one area that I feel Bulls could rethink or improve in the future.

There’s a lot to praise and celebrate with the 2018 BULLS Lacuba EVO E8 electric bike. It’s almost like three bikes in one because of the frame and sizing options. I love that the key for locking the battery here comes with a code card so you can order locks from ABUS that will use the same key cut, and avoid clutter. I appreciate the overbuilt chain guide, the little flick bell, and the premium Ergon ergonomic grips. Tony, the random neighbor who took a test ride during the review, came back thrilled, and I think there were just so many new and premium parts on the bike that he had never seen… it really surprised him. Yes, these parts do cost more, but I think Bulls is offering a ton of value here at a very reasonable price, and even at ~57 lbs, I feel that the bike is not heavy. Remember, the high capacity battery, internally geared hub, reinforced frame, rack, fenders, lights, larger gel saddle with bumpers, and kickstand all add weight. Thankfully, they also add a ton of utility. And, stopping the weight of this bike should be easy, even if you have weaker hands or smaller hands, because it comes with Shimano hydraulic disc brakes. The front rotor is mount bike sized at 180 mm and provides a greater mechanical advantage. The tires on this bike are wider than most 700c size, at 2-inches, an that adds a bit of weight but also improves stability and comfort. I was a little surprised that the smaller frame size (the one I tested) didn’t come with 26″ diameter tires vs. 28″ because that would have lowered the frame and offered a stopping advantage. But what you get instead is a lower attack angle to smooth out cracks and higher air volume to provide more give. It’s the same direction they went with for the Cruiser E model. Compared to that bike, I found the Lacuba Evo E8 to be quieter and suffer less from speed wobble and frame flex. This would be my personal choice, but I have to admit that the aesthetics and sturdier fenders on that model are very appealing. I like that the rear fender connects to the cargo rack here, and that the rack is positioned further back so that the saddle can be lowered way down if you have shorter legs. The hydraulic disc brake levers are also adjustable for people who are petite, so the levers can be brought back further. I’d like to thank Bulls for partnering with me on this post, and providing their entire 2018 lineup for me to explore back to back so that I could get deeper insights. As always, I’ll try to answer questions in the comments below and I appreciate your own thoughts and feedback to help others, you can also engage in the BULLS ebike forums to share your own pictures etc.


  • Designed and accessorized for comfort, the medium-sized gel saddle, adjustable stem with swept-back handlebars, name-brand ergonomic grips, and adjustable air suspension fork make a big difference… even the 2″ wide tires are fatter than average which provide cushion and stability
  • Available in four frame sizes and three different styles! You can aim for stiffness with the high-step or approachability with the mid-step and wave models, the wave will experience the most frame flex but with the top assisted speed of 20 mph, this shouldn’t be as much of an issue, especially for relaxed neighborhood rides
  • Beautifully integrated motor and battery system, you can hardly tell it’s an electric bike at all given how compact and integrated the systems are, the motor is also extremely quiet
  • Internally gered hubs tend to be cleaner and more durable than cassettes and derailleurs, the chain doesn’t have to jump to different sprockets so it will be less likely to fall off when riding and it won’t be strained by the mid-motor as much
  • Full-sized fenders and a longer chain cover with chainring guide will keep your pants, skirt, or dress clean while riding, feet and shins may still get a bit wet if you pass through deeper puddles
  • I feel that the grey/red color combination could work well for any type of rider, it’s gender neutral, and I love that the tires have reflective stripes and you get integrated LED lights here for safety, especially because the frame is a bit darker color
  • It’s a minor praise, but I appreciate the addition of bottle cage bosses here, they could be use to transport fluids and make it easier to reach vs. using a trunk bag with a bottle holster like this
  • The 647.5 watt hour battery capacity here is quite a bit above average compared to most of the electric bikes I see and test which are around 500 wh, this will allow you to ride further but the pack does weigh about one pound more at ~7.1 lbs
  • Brose motors are quiet and smooth, the T (trekking) model is a bit more mellow than the new S model making it well-suited to neighborhood and urban riding, it’s very compact and hidden behind the chainring on this ebike and because it uses a Gates carbon belt system inside, it doesn’t vibrate as much when pedaling
  • Weighing in at about 57 lbs, I would consider this product to be lightweight given that it has the larger battery, fenders, rear-rack, lights, and a custom approachable frame, the high and mid-step models might be even lighter but I could not weigh them
  • By adjusting the stem, I was able to create a very comfortable upright body position for the ride tests, and I loved how big and bright the display panel was, it’s easy to read and use while riding and I appreciate that it can be removed easily for protection when parked
  • High-quality Shimano hydraulic disc brakes with adjustable-reach levers, the rear rack is setup to handle clip-on panniers like this and keep them from rubbing on the wider tire, the kickstand is positioned well to stay out of the way and offers length adjustment
  • I love that the suspension fork uses air vs. spring because that means you can lower the pressure if you’re a lightweight rider (like me, at ~135 lbs), the fork also has lockout so heavier riders can reduce bob when pedaling and dive when stopping, it has a quick release skewer so be sure to lock your front wheel, the seat, and the frame when parking
  • This was one of the most popular electric bikes that Bulls made in 2017 and they managed to lower the price by $200 for 2018! I think it offers great value at $3,799 considering all of the features, the premium motor, and the larger battery… they cut the price down in part by removing the belt drive and going with a standard chain
  • I would consider this bike to be more tough, there isn’t a derailleur that could get bumped out of true, the chainring has a full guide to prevent drops, and the Brose motors are known for being higher quality and require no maintenance
  • Schwalbe makes high-quality tires and the Big Apple model used here offers some puncture protective lining so you won’t get flats as easily
  • The battery pack has been improved since 2017, the base now has a tougher rubber guard to keep dirt and rocks from scratching it while you ride and the locking core and charging port are positioned in a safer spot, I like that they still use a magnetic charging port to allow the cable to pop out if you trip over it vs. tipping the bike and bending the plug end piece
  • I love that the display is removable because it’s so big and beautiful… I wouldn’t want it to get scratched or marred up by the sun and rain at the bike rack, and this display has a Micro USB port built into the base to fill your phone or other portable electronic devices on the go!


  • The deepest wave, step-thru, frame does experience some frame flex, this reduces pedal efficiency and may contribute to speed wobble of the front wheel depending on how much the rider weighs, how the body position is setup, and whether the rear rack is loaded… it’s not a big issue, just keep both hands on the bars if you notice a bit of wobble on the front wheel at higher speeds
  • The headlight is aimable but positioned pretty low towards the front fender and wheel, it may not shine directly down onto the street and just isn’t as powerful as other options I have seen (it seems like more of a “be seen” solution than a “light the way”), it’s also mounted to the suspension arch which will bounce up and down vs. the head tube or handlebars on the bike which are suspended
  • The grip shifter is intuitive but not as fast as triggers, and sometimes internally geared hubs will not shift as quickly (especially if you are pedaling hard or the motor is helping), it’s not a major gripe but it can take some getting used to
  • The stock pedals are a bit basic, if you are a larger rider with big feet or someone who is heavy and want a more sturdy platform, consider swapping them with something affordable but tough like these Wellgo pedals
  • The plastic fenders do rattle around a bit if you ride on bumpy terrain, tubular Aluminum alloy fenders would be quieter but add weight and cost and steel fenders could get scratched and rust, so I think these make good sense here and I love that the rear fender attaches to the rear rack for extra strength
  • The pack detaches downwards and requires a bit of hand strength and balance to hold when unlocking, so just keep an extra close eye on it and make sure the bike is stable fi you decide to remove the pack, most people will probably just leave it on the bike and charge that way for convenience but it can reduce the weight of the bike and protect the battery from extreme heat and cold by removing it
  • The center button on the control pad (located near the left grip) is touch sensitive… and I found that it was easily activated even when I really didn’t want to change menus, I think I prefer a standard button vs. the touch interface because its more intentional and probably works with gloves better
  • The battery charger is a bit bulky and heavy, it weighs ~2.5 lbs but puts out 4 Amps vs. most standard chargers that just put 2 Amps, I do like the magnetic end piece but make sure not to drop it in the sand or little iron filings may stick to it

Hey, nice review of the 2 recent Bulls bikes. Oddly, the videos are not appearing on your Youtube page?

2 months ago

Thanks for the heads up KD! I have purposefully not published the videos there because Bulls does not yet have their inventory. I wanted to share the content, to let people become aware and study it… but not overload them with questions and orders because there’s usually a rush of interest when videos go public on YouTube, for now they are live but unlisted, you are welcome to share them and some shops are embedding them on their store websites :)

Thanks for the info. Do you know when stores will be getting inventory in for the EVO E8? Is it generally in the summer?

Hi. I was wondering if the battery pack of the 2018 fit the 2017 model and vice versa? Thanks.

2 months ago

Great question! I reached out to Bulls and was told the following about Brose battery interchangeability: “The previous 2017 battery (with foam sticker) will be compatible on the 2018 models – however it may not look very aesthetically appealing without the rubber shim. However, the new 2018 battery pack (with the rubber shim) will not be backwards compatible on the 2017 models because the shim does not fit into the frame.”

2 months ago

Thanks Court. So I assume the shim on the 2018 battery is not removable? Because as I understand it, the only reason a 2018 battery cannot fit a 2017 bike is the rubber shim on the 2018 pack, so if it can be removed then logically it should fit the earlier models?

2 months ago

Hello My, I asked for further clarification and was provided with this information: “It is the same battery, however, the 2018 version comes with a rubber shim glued to it. The shim is glued and is not meant to be re-used (although it could technically be removed and then re-glued to another battery). We wouldn’t recommend to re-using them and we do carry extra rubber shims in case one of our dealers wants to purchase one.” I hope this helps!

KD, Just to answer your question about delivery, we are expecting the first shipment of the Bulls Evo E8 to arrive in our shop the first week or May 2018.

Hope this helps,

I’ve been looking for an electric bike that I can ride around the paved streets in my neighborhood. There are a lot of hills and some of them are pretty steep. I’m 68 years old, 5′-9″ and 175 lbs. I’m not the strongest rider so I’m interested in a bike that will make hill climbing the easiest. I like what I’ve read about the Bulls lacuba evo e8 and I enjoyed listening to your review. I know that it comes with the brose drive T motor. Do you know if Bulls plans to upgrade to the brose drive S motor in the future or is the S motor strictly for mountain bikes? Would an eUrban bike like the Haibike SDURO Trekking 9.0 with a Bosch performance CX motor be a better choice for climbing hills? Thank you.

1 month ago

Hi Al! My experience with Bulls has been that the motor is quiet and fluid. Technically, it is rated at higher torque than even the Bosch CX which has 74 Newton meters. All of the Brose models have 90 Nm… The new S motor sounds more powerful and efficient, so I wonder why all of them aren’t switched? Perhaps it has to do with more noise being produced and a sportier feel. I personally think that the Brose T is still a fantastic motor and would be more than enough for your hills… especially if they are paved hills vs. mountain. Remember, in 2016 and 2017 the Bulls mountain models also used the Brose T motor, the S is brand new for 2018 in America :)

XM700 is listed on Trek website as 2018 ; has it been discontinued ?
I think new model line up is announced late summer ?
I'd like to see the XM700 develop into something similar to the Bulls Urban EVO ; 500 Wh battery , 700c x50 tires , Suntour fork .

The Swedish Bike Show in Stockholm this weekend wasnt much to write home about.

It was the big swedish retailers showing off their bikes and only some ebikes from standard brands like Scott, Merida, ecoRide, Wallerang, Crescent, Monark etc.

No smaller retailer with any for me more exciting and interesting brands where there like Bulls, R&M, Haibike, Stromer, Cube or Moustache.

I will go to Elovelo (ebike store in Stockholm) this week and test ride and compare R&M and Moustache.

The search continues!

Hello fellow Swedes!
So im in the same position as you are. Been researching for over a year now.
Me and my spouse have moved from the city to the more rural forests of Närke and we want to go more sustainable.
To replace the diselvan as much as possible is our goal.

I've been reading everything and watched so many reviews from different manufacturers and i can't really decide.

So this Saturday we went and bought a rawbike from "blocket" for 12k SEK. It's a class II moped, 750w, 48v 15.4 Ah. 25km/h topspeed but i unlocked it to 35km/h. It's for my spouse so she can go to the bus and home.
We have a hill that is 3.5km long and has an elevation of 150m. I have to take that one home after working 12h nightshift.

For myself i cant decide what to buy. I'd like an electric ATV but there is only kidsized ones available.

The models i have researched so far:
Haibike trekking 7.5 or 4.0 (dual battery)
R&M - all of them, but supercomuter with 2x500w is the one i think.
Bulls Evo street http://www.pro-e-bike.se/sv/elcyklar-emtb-ebike/marken/bulls-six50-evo-street.html
Scott Sub Tour 10
Butcher and bicycles cargobike

Radrhino fatbike 750w - the Eu model is not updated with the larger battery yet according to their website.

My requirements are Bosch CX and 500wh battery. I'd like a dual battery setup since i have 25km to the city and i want to make sure i can go home at max assist and speed if i need.
And yes i will buy a dongle for it if i get one.

I think there is not much that differs between these models. Motor and battery is key. The rest i "meh".

But then there is the Super soco moped with 2kw and 29Ah battery for 32k SEK with option for another battery.
With the new EU rules there is the speed bikes too. Elcykelguiden.se had an article about it and they mentioned this site:

2kw, 60v 18Ah and topspeed 60km/h for 23k and possible less if you are chosen as a testpilot. I sent an email yesterday.
I like fatbikes and have an Kona Wozo fatbike as my current MTB.

E-Bike or Moped or something in between... That is the question.

Have a 2016 FullSeven Xduro RC and it came with Rock Shox 120mm travel Recon solo air forks. They were OK, but nothing like the Pikes on my Bulls. Also liked the slacker 66 degree head angle on the Bulls as apposed to the 69 degrees on the RC. I found a great deal on a new 160mm travel Lyrik but wondered if installing the longer travel forks on the 120mm travel frame would mess up the geometry. Turns out it totally improved the handling far more than even hoped! Don't notice the higher BB (maybe 20mm), but it gave me about 1 degree slacker head angle and just makes the bike so much better for the rocky terrain I ride. Before the upgrade I preferred my Brose powered Bulls, but now with the new fork and the e-Mtb mode software upgrade it's a total toss up!

I'm wondering if the geometry of this series of Haibike frames are pretty much the same. A buddy has the same year Sduro AMT with 150mm front and rear suspension and it has a 68 head angle which is the same as I now have.

i been looking hard at Rad products. i like the way they answer questions. I did ride an older model rad city and it was soooo nice. I also rode a BULLS EVO and that was really nice... different ride all together. I am checking used bikes now and shops that sell used. I think for noobs an accessible repair guy is key. I'm prolly going with the rad mini but its hard too make up my mind... i think carr--less folks with e-bikes are the new badass's in town

The belts are a great low maintenance feature found on several bikes. Riese & Muller is probably the largest ebike manufacturer to offer these on many of their models.

Bulls also have the 2017 Lacuba E8 that uses the Shimano Nexus / Belt set up which is great. https://shop-usa.scooteretti.com/products/bulls-lacuba-evo-e8

Once people know and hear about the benefits of going with a belt we should hopefully see more and more manufacturers producing models for the NA market. The issue, for now, is basically the price as many NA's are still very price sensitive vs many EU regions when it comes to how much they want to pay for their bikes.

But the long-term benefits of these products should actually cost the owner less to operate and certainly require less maintenance which can be very convenient for a lot of people.

Hey guys, today while visiting the Raleigh Electric headquarters in Southern California, I was able to check out the 2018 Tamland iE ebike, which uses the Original LCD-Display from Brose, with the Brose Drive TF (Fast) motor unit. This display is one of my favorites because it's fairly large and easy to read, removable for safe storage, and the mount has a full sized USB Type A (5 volt, 500 milliamp) port built in to charge or maintain your portable electronics. There are two parts to this display: the LCD unit and an independent button pad which can be mounted within reach of either grip. The video below goes into detail but does not explain how to set the clock or how to show range estimates... sorry, I welcome your input in the comments below!

Navigation aids:

[*]How to remove the display at 0:12
[*]How to activate the display at 0:48
[*]How to clear stats at 1:37
[*]How to activate walk mode at 2:32
[*]How to change units (miles to kilometers) at 2:56

Quick tips:

[*]The buttons on the LCD include: Power, Lights, and Menu.
[*]The buttons on the independent button pad include: Up, Menu, Down.
[*]To reset trip distance, average speed, max speed, hold Menu and Lights on the display unit
[*]To activate walk mode, arrow down to no assist (you may see a little triangle next to the speed readout), then hold the down arrow.
[*]To change units from miles to kilometers, turn the battery pack on first, then turn the display off, then hold the menu key and power button on the display. I had to do this one a few times, it seemed inconsistent, but it does work :)

Things I like about the display:

[*]It goes bright for a second when you press any of the buttons... then slowly dims.
[*]It's removable, so it won't get scratched or weather-worn over time if the bike is parked outside.
[*]There's a USB port in the base of the display
[*]This display doesn't require its own coin battery like the Yamah and Bosch Intuvia displays do
[*]I like how the battery will stay active for two hours once you press the power button, this allows you to turn the bike on and off just using the display. After two hours, the battery goes into deep sleep mode.
[*]The display does have a range estimate menu, which I did not go into on this video. You can navigate there by pressing the menu button and it will update automatically as you change assist settings (Cruise, Tour, Sport)

Things that might be improved about the display:

[*]It has more menus that some of the other displays and the manual was a little confusing, do we really need total trip time? It always said zero for my test bike...
[*]The slide design to fit the display onto the mount does not start at the very top, you have to almost put the display down near the middle, then slide for a shorter section to have it click, and this always confuses me.
[*]It seems like you have to manually power on the battery pack with Brose drive systems, which could require a reach down or back, it would be nice if you could activate the bike directly with the on/off switch on the display like most other high-end ebike systems
[*]The Brose battery pack often uses a magnetic Rosenberger charging port which has a little rubber plug... but there's no leash or connector for the plug, and that makes it very easy to misplace and lose.

As mentioned in the video above, I have attached photographs of the official Brose instruction manual below (sorry about the limited quality, I took photos and then cropped them manually with a bit of contrast tweaks to be readable). The http://www.brose-ebike.com/ seems to be short on information about this particular display and it seems like they may open design up to OEM manufacturers like Bulls, Specialized, and others to make custom displays. You can see this on the Specialized https://electricbikereview.com/specialized/turbo-vado-6-0/ (which has two display options, one is a touch screen) and the https://electricbikereview.com/specialized/turbo-levo-fsr-comp-6fattie/ (which just had three buttons and a Bluetooth smartphone app). This particular display panel is Brose branded and is their original layout (as far as I can tell).

Using the word "best" opens up a whole debate. It really boils down to personal preference and fit of the bike, and riding style. My original intention was to buy a Bulls bike, but a demo deal on a Haibike made the decision much easier for me.

When researching for my recent ebike purchase, I was putting Bulls in the same category as Stromers: European-made, very high-quality, and expensive. If it was in my price range, I would definitely have seriously considered.

Hello Boca,

I am sorry to hear about the problems you are experiencing, and I am also sorry I cannot be of any real help. However, I share with you the frustration of being a 'proud' owner of a Bulls Lacuba EVO 8. Mine is also 6 months old, and I reported the issues I have here and on other sites. As you did, I spent a small fortune to have the dubious privilege of having one. Besides having the 'wobbling issue' I described elsewhere, I also have electrical problems. In my case, the power will suddenly go OFF, meaning if you are climbing a hill, the bike loses power instantaneously. This can be a very dangerous situation. Nothing to say that you are clueless as to how to make the bike usable again. Of course, this has NOTHING to do with the charge of the battery. In ALL occasions the battery is FULL. It also happens from time to time not only while riding but when you are just starting a ride, meaning starting with a FULL battery. So far the only guess and solution I found were to unlock the battery, clean the internal contacts and lock it again into position. Also, to make sure the contacts between the 'control panel' and its sitting/lock are clean. I noticed humidity can and does condense there, preventing a good contact.

I would suggest trying to do a charge with the battery off the bike. If you have contact cleaner, clean the contacts on both sides, the battery and the charger plug end. The contacts should look bright, NOT greyish.

The lesson I learned is clear. Given their complexity and their price, we should approach getting one as when buying a vehicle. To put it in short, buy from a dealer that is close to you, that you can bring the bike, that will provide technical service, proper solutions and stand behind the manufacturer's warranty.

All the best,

I have two 6 month old Bulls Lacuba EVO E8's and have two electrical issues.

First one battery would only charge to four lights or 80 %. I was in the habit of charging after each ride when the batteries were no lower than 80 %. The chargers would charge but you couldn't tell they were charged by looking at the charger light because they never went solid green when charged.

Recently I decided not to recharge after each ride because I had a lot of battery capacity. We went on a 30 ride in hilly terrain and still had 80 % left. So, recently I ran the batteries down to one light (20 %) and two lights (40 %). Now neither battery will charge. I know to plug the charger into the battery before plugging the charger into the wall.

Any ideas?

I really like your lights and bag. Do you have some links to those?

Maybe you can raise the stem with https://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dsporting&field-keywords=stem+riser+bike Stem Risers, instead of replacing the stem? Having a higher stem would definitely make it more upright/city bike, which is something I loved about the Bulls Lacuba Evo e8.

Stromers were nice
I like the Gates belt drive no maintenace and no derailer
Our Bulls climb hills at 15+ mph
They are up to the task
If you spend some time reading about these motors its about dc voltage and torque, so thebest hill climbers are the mountain ebikes
we werent going to be going crazy on mountain trails so I stayed with a more hybrid style
You should be able to rent an ebike for a day and give it a real test

Thanks Art - good to hear from you!

I tried out a few bikes yesterday -- the Bulls Lacuba EVO E8 (is this the bike your wife has?), a Stromer platinum, and a Raleigh Redux. I'm curious what you think about the belt drive as opposed to the chain? and how does the Bulls Lacuba fare on the hills in Colorado? The shops only let us ride around in a flat parking lot. Did you try Stromers? Were there any other bikes that you felt were contenders?

Update: I've posted pictures and updated the review https://philrw.wordpress.com/2017/08/30/2016-tempo-carmel-electric-bike-review/.

I had test ridden and researched quite a few ebikes lately in search for a bike that had most (if not all) of the following specs (much like https://electricbikereview.com/forum/threads/nuvinci-sourcing-and-installing-in-the-bay-area.14143/):

[*]mid-drive, class 1
[*]traditional high-step frame for extra stability
[*]upright seating posture for comfort, keep weight off my hands as much as possible
[*]front suspension
[*]hydraulic disc brakes
[*]NuVinci transmission with Harmony or H|Sync automatic shifting
[*]Gates belt drive for long term durability, quiet/smooth, and (potentially) lower long-term maintenance
[*]integrated light(s), if possible

I happened across a 2016 http://tempobicycles.com/carmel/ at a small local bike shop and gave it a test ride. I wasn't expecting or even looking for the bike, but there it was. And it was a lot of fun. After testing out a few more bikes, I decided the Carmel was the bike for me, so I purchased it for what I felt was a very good price and rode it 11 miles home, the last couple up a relatively long hill. Google Maps says it's 262 feet over 1.5 miles, which makes it a 3.3% grade. I currently weigh 98 kg and I was carrying at least 5 kg on my back. For the steepest part of the hill (4.8% grade over 0.4 miles), the bike kept up a solid 7 mph in maximum assist. I am 5'10" and the large/48cm frame fits me nicely. Granted, I still had to work, too, but it didn't kill me and I'm not in great shape (yet). I wasn't sweaty by the top of the hill.

I believe the motor is the MPF 6c, which the spec sheet says is 75 Nm of torque and 250 W nominal, 500W peak. The motor itself is incredibly responsive and quiet, about as quiet as the Brose motor on the Bulls Lacuba Evo E8 I tried. I believe it might be limited to the international 25kph standard? (More ride research is needed here.) The bike doesn't have brake inhibiters but doesn't need them because the motor stops a fraction of a second after you stop pedaling. Also, the belt drive makes this bike very quiet and smooth. Honestly I couldn't hear the bike that much at all working up the hill in 100% assist mode. The motor was responsive enough to highlight my own faults as a cyclist: inconsistent delivery of power to the pedals. I'll get better over time. :)

The bike came with the N360 hub and the 3-button base controller (H3). The preprogrammed cadence speeds are approximately 40, 55, and 70 rpm (see http://harmony.fallbrooktech.net/updatefiles/Harmony-OEMInstallation.pdf for more details on the system). I have not tried a bike with the advanced controller yet (H8), but so far I am happy with the three speeds. I might eventually change out the controller. I typically stayed with the middle 55-rpm mode and was pleasantly surprised how steady my cadence was. One time after I decelerated more rapidly than normal, I started pedaling again and was in a much "lower gear," or faster cadence, than I expected. I think I fooled the controller into believing I was going to come to a complete stop. It quickly recovered. Since I had several stops and intersections on my route home, I was glad not to have to constantly shift down. In fact, It was nice not thinking much about shifting at all, and even though I am totally capable of managing that part of the ride, I was able to spend my mental energy elsewhere.

The handling of the Tempo was quite nice on dry pavement and I felt more confident with this bike than my previous bikes (of course, that's not saying much given my previous models). It corners nicely and is stable at 30+ mph downhill. The tires have a nice hybrid tread pattern for pavement and packed gravel trails, and they have a reflective sidewall as well.

On to the controls: There is a five-button controller near the left grip with +, -, light, mode, and walk. The MPF-branded computer doesn't give an estimated range remaining display, but it does have odometer, trip distance, trip time, average speed, max speed, and clock. Always on the display, from left to right, are assist level (10 levels!), speed, cadence rpm, and 5-segment battery meter. There is a backlight and a micro-USB port on the controller, and the only button on the display unit is the power button. It is detachable and has its own coin cell backup power supply.

There are hydraulic disc brakes on both wheels and the front light is wired into the controller and runs off of the main battery. The rear light is battery powered and only blinks (at least I can't get it to do anything else). It's probably more energy efficient to blink a battery-powered LED anyway. Walk mode works by holding down the dedicated walk button. There are the typical bosses for fenders and racks, although it might be tough fitting a fender to the front fork since there is little clearance between it and the tire. Also, the front suspension is a single-spring system with pretension adjustment and no lock-out. I figure it's fine for my purposes and may even be more reliable long-term than a more sophisticated dual-piston system. The seat post also has suspension on it. I found myself sinking into it after riding for a while. Maybe there's an adjustment on it, I'll have to look.

My other top contenders were the Felt Verza E 10, the Bulls Lacuba Evo E8, and the Wallerang. The Felt uses the Bosch system and both the local dealers that I tried were having trouble with some of the the display/head units. The Bulls is a nice bike but I really wanted the NuVinci automatic shifting for a truly brain-dead biking experience. :) Also the Wallerang Di2 auto-shifting with the Alfine 8 was really cool.

Please ask away any question(s) you may have about this bike! I'm excited to have a more modern and responsive ebike. My last one is/was a Currie eZip Trailz that I converted from SLA to Lithium.

This morning I had the bike checked -again- at a different bike shop. The third inspection and in this case, to get another independent opinion.
They were NOT able to find anything out of order, including checking the torque on everything 'torquable' and particularly in reference to Bull's last request, to have the front spokes checked.

I am NOT blaming anybody but myself. However, one of the main considerations for the selection was the fact that it was rated as the Number 1 by EBR in Best City Electric Bikes for 2016/2017 category And yes, I rode it, I compared it with other bikes and this one was by far the one that, for me, offered the best riding position given my physical limitations.

I posted the same letter that initiated this thread on EBR review. I got a response from the reviewer that, to make it short, I am not quoting here (you can see it in the review). However, I am quoting here a paragraph from my response to the reviewer:

..... I didn’t mention this before but just minutes after my first ‘wobble encounter’, I took the bike to a highly recognized bike shop. I live in a very particular place, on the Sunshine Coast of British Columbia, Canada. Mountain biking is VERY sophisticated here all year, and those guys work only with mountain bikes. The first thing they saw was my terrified face, the only one I could’ve to have after being so close to smashing 260 lbs at 30 miles/h against a boulder or a tree (no difference). Then they looked at my bike and both mechanics said: no wonders you didn’t get killed already with that *sh&%@y* fork. Well…, I became quite disappointed. Having paid a fortune for this bike I thought the components were equivalent -kind of- to having a Porsche class bike. True, just a Boxster, but a Porsche nevertheless. Then, I started to look at all the other components and, frankly, they are quite low-level. So what did I pay for? a battery? technology? Wobbling excitement?

I appreciate your comment and suggestions, and this is precisely the reason of why I initiated this thread in this forum and the title I gave to it: "RECALL and DISCONTINUE LACUBA EVO E8 WAVE"

I am packing the bike and shipping it back to the vendor. I'll keep you posted.

I bought an E-bike (2013 Izip E3 Metro) a few years ago, and don't ride it much . . primarily because I think I'm scared of the thing. It's power is a bit unpredictable to me (caused me to fall almost immediately after getting it), and just doesn't feel natural.

I now think that a mid-drive with a GOOD system will alleviate much of this. The Benno Eboost really caught my attention (probably won't actually use the ability to carry cargo, but I want the option, will probably buy all the racks and bags). And to be completely honest, I just love the "story" that goes with the Benno bikes. Or maybe I'm just attracted to "different" and what some people would call "ugly" bikes (I got the Metro in ORANGE, and would get the Benno in yellow).

I can't find a local dealer that has the Benno to drive, but I did drive an Easy Motion Atom Diamond (Brose drive with Shimano Nexus IGH) and some other bike that had the Bosch system with a 10-speed derailler (like the Benno). Both drives seemed fine to me, but the SMOOTHNESS of the Brose/Nexus system (primarily due to the IGH, I'm sure) really struck me. And the quietness.

Now, it's possible that the bike I rode with the Bosch simply didn't have the derailler properly adjusted that led to the lack of smoothness.

I really like the BIG tires on the Benno Eboost, pretty sure I'd like the 24" x 2.6" tires, and the whole bike. But it keeps bugging me that the Brose/Nexus just seemed soooo smooth.

It looks like perhaps a Bulls Lacuba EVO E8 would get me the Brose/Nexus drive system with larger tires (2" vs 1.5" of the Easy Motion, but still not the 2.6" of the Beeno or the 24" wheel diameter.

Any other bikes I should be looking at? Or should I just get the Benno and not worry about the derailler and the lack of smoothness I detected in the bike I test-drove? I guess I should go test-drive another bike or two somewhere with the Bosch system if I can find one.

Anybody got the Benno Boost and love it or hate it?

Thanks @RA
I am attaching a photo and made a composite of it. On the left, and marked with a RED CIRCLE, is the photo sent from BULLS to my vendor/dealer explaining how the seat post is attached to the front of the bike. The explanation from BULLS to the photo is quote: As I mentioned on the phone this is the first claim we’ve heard of a Lacuba EVO E8 having any speed wobble. Our wave frame doesn’t have a top tube but is strengthened with a wide downtube and also a reinforcement tube that’s welded at the “dip” (pics attached) end of quote. The BULLS photo -on the left- is the one with the RED CIRCLE. On the right, is a photo of my bike, which I submitted back to my vendor, which is going to be sent to BULLS including my own comment: I composed a photo whereas the original you sent -with the red circle- is on the left. My bike is on the right shown with the measuring tape. If you count the number of welding 'spots', there is a difference of 3 welding spots between both bikes. Assuming each weld is of the same thickness, the height of the (almost) triangular piece welded between the vertical and horizontal bars must be different: higher on the triangular piece of the BULLS photo. Also, and this might be just an illusion due to the angle of the photo, I have the impression that the triangular piece marked on the red circle is higher and steeper than the one on my bike.
I'll keep you posted and many thanks for your interest.

I feel your pain. I wonder if the wobble you are describing is the same as in the video at 21:39.

If that's the case, then your ebike does not have enough torsional rigidity to handle the payload. The LACUBA EVO E8 WAVE only has the down tube attached to the seat tube, and has no top tube that enhances the strength and rigidity. I suggest you try to ride the high step version or the BULLS Lacuba EVO E45 which has similar frame but with the top tube, and then see if you can still duplicate the problem. Either way, I think you should exchange your ebike since it is not safe for you.

Here is educational video on speed wobble.

This is a copy of the email sent to Citrus Cycle and to BULLS on August 14, 2017

I bought an LACUBA EVO E8 WAVE from Citrus Cycle, Kelly Demoline, Ladysmith, BC, Canada on May 31, 2017. The choice of this model was due to my physical conditions. A few years ago I had an accident suffering serious injuries in my neck. As a consequence, my neck is fused, limiting my head movement. I have been an active bicycle rider, both mountain, and road- all my life, but since the accident, I was not able to get back to riding anyone.

Meeting Kelly Dmoline from Citrus Cycles changed all this once he introduced me the EVO E8 Wave.
It's riding position was just perfect for me, absolutely comfortable and the pedal-assisted feature made possible for me to get back safely to the road.

Unfortunately, and just within a couple of days, I had a terrifying and literally life threatening experience. While 'testing' the bike downhill on a paved road, reaching about 40 k/h (not pedaling) the bike started to wobble violently. Only thanks to the experience I have riding bicycles I was able to stop it safely.

The experience was so shocking that I immediately contacted Kelly Demoline, having decided to return the bike. He was very surprised about the issue but, without hesitation, was ready to take the bike back.

Overnight I thought about it, about how much the bike was going to give me back to my life, that I decided to keep it with the condition I set to myself to never get to 40 km/h again.

However, the problem subsisted at different speeds, 30, 25, 20 km/k and so. I kept trying to figure out what may be out of line to induce such a behavior. I have the bike checked in a bike shop without finding anything abnormal. All they did was to adjust the suspension fork pressure for my weight, 200 lbs.

Finally, today August 15, 2017, with the odometer at 179 km I was able to induce and reproduce the problem myself AT ANY SPEED.

Riding the bike on a paved road with enough grade to force the bike to increase its speed, WITHOUT PEDALING, once reaching about 15 km/h start jiggling the handlebar left-right right left quite fast. The movement will induce a wobble on the front end that will rapidly be transferred, amplified to the back, reaching its maximum where most of the weight is concentrated. I tend to think the weight and location of the battery are crucial components in this wave resonance / dynamic amplification problem.

The meaning of this is that just a pebble, pothole or any irregularity on the road may lead to a 'handlebar jiggle', inducing the wobbling effect AT ANY SPEED.

That's exactly why it happens to me so many times and at different speeds.

I understand the problem is magnified due to the typical riding position of an urban type bike, where there is limited rider's weight on the handlebars.

Another situation associated with the weight on the handlebars is when making a traffic signal: a single hand on the handlebar and very little control upon the jiggling/wobbling effect with the other hand.

To summarize, I do not believe there is nothing technically wrong or defective with my particular bicycle.

However, I strongly believe there is a conceptual flaw in the design of this particular model, making it unsafe to ride it to the point that it should be discontinued and a recall issued.

The best and worst thing about this bike is the battery. Best because it's one of the best battery available on any Class 1 ebike as far as range is concerned. Worst because of where it's housed, i.e. the under the top frame. You're guaranteed to drop it one day no matter how careful you are in removing or putting it back. A replacement battery costs an arm and a leg.

I ride Bulls Lacuba EVO e8 2017 diamond frame model. I'm very satisfied through winter season with Gates CDX belt drive solution. Whereby have unusual few frosty days this winter being more cold cloudy and wet here. The 2018 model shows improvement regarding accu key lock position. I love the Brose motor having its characteristic as described by you. One accu dash in display lasts about 20 to 25 km. So operate 90km/56mls in small hill area isn't a problem. For even more comfort I added a Thudbuster ST seat post. At the end of winter I will remove winter spike tyres and change to Schwalbe Big Ben Plus getting a bit more grip in forest. I didn't like that light position too and moved it to handle bar after bought approbriate mount. If you consider to do same check cable length first because they use a special plug. My only dislike about that pedelec is the front fender tends to make rattle noises. Tighten cable zip ties to lower mount point reduced most of those noises. Also it is too short doesn't protect accu and shoes well. For a few bucks added SKS 50-60mm mud protector long style.
In general I would buy a Brose model again but would miss that extra lifestyle belt drive.

I forgot to mention after about 1000km getting ugly squeak noises while pedaling. First I was afraid of the belt could be that noise maker. But removing pedal dust cover and plenty lubricate the pedals that noise has never reoccurred.

Seems like some compromise for a bike at that price. I hope you can help me find the right bike for my family before spring. Want a step through with European safety standards, walk mode, panniers, and throttle. One will be for my elderly mom who wants to ride with us.
