Written Review

The Lacuba Evo E8 is like an “everything electric bike” because it comes in five sizes, three different frame styles, has fenders, a rack, suspension fork, integrated lights, a large battery and an efficient mid-drive motor. I guess it’s not well suited to trails and mountain biking… but the motor used here, from Brose, is the same one that Bulls uses on their very capable full suspension mountain models! With 90 Newton meters of torque and a 250 watt nominal output, the bike is no slouch. What really sets it apart from some competing models is the internally geared hub running on a Carbon reinforced belt drive. You don’t have to worry as much about a derailleur getting bumped or a chain falling off. There’s no grease and oil to deal with and you can shift gears anytime (even at standstill). One trade-off with this setup is that the rear wheel uses bolts instead of a quick release skewer but the tires are higher quality Kevlar-lined models that shouldn’t be as susceptible to punctures from thorns or glass. Also, the front wheel does have quick release so maybe half the time it will still be easier to change the flat. Also worth noting is the compact mini-pump that clips into the rear cargo rack. Low tire pressure is a leading cause of pinch flats and can contribute to lower efficiency so having that pump with you at all times should further reduce instances of flat tires… just make sure you don’t leave it on the frame to get stolen at the bike rack :/

In my opinion, Bulls has done an excellent job outfitting the Lacuba EVO E8 with name brand hardware that will last longer and reduce weight while still hitting an impressive value price point. No, it’s not super cheap at just over $4k but the reflective sidewall stripes on the upgraded tires could save your life along with the integrated LED lights front and rear. The Selle Royal saddle significantly improves comfort when combined with the air suspension fork and adjustable angle stem… not to mention ergonomic grips (again name brand) from Ergon. You can spend a lot of money swapping saddles and changing touch points and end up with a bike that doesn’t look as good as this. The fenders are tight and have sturdy struts and attachment points on the rear rack so they don’t rattle. You get a chainguard that keeps your pants from rubbing on the belt, but even if this wasn’t here you’d stay a lot cleaner than if it was running a chain. Designing frames that have a cut-away for actually using a belt (since the belt can’t be unlinked like chains can) is expensive and I’m just amazed that they did it for five frame sizes and all of the different frame types. I especially like the step-thru and low-step wave because it’s a lot easier to mount the bike than swinging your leg up and over the rear rack (especially if you’ve got a trunk bag mounted there). This is an electric bike that should fit most riders and be more fun and secure for shorter petite riders like women. My girlfriend has hit her leg and crotch many a time riding other bicycles and it creates insecurity and she doesn’t want to ride as much. Yes, the wave model that I test rode and photographed for this review isn’t going to be as stiff as the mid-step or high-step diamond or as easy to mount on some car racks but at least she will want to go riding and this isn’t a bike that needs to be so stiff.

I love the battery and motor integration, both are tight so you don’t hear rattling and they blend right in with the frame. It only comes in one color scheme but it’s professional and helps the black battery and motor casing blend in… along with the black cables (many of which are routed through the frame to reduce snags). Even though this has a downtube battery, because it mounts up from the bottom, there are screws for mounting a bottle cage on all of the different frame styles. This is great because we all need hydration! Surprisingly, many electric bikes forego bottle cage bosses and while you can compromise with a bag or seat mount they just aren’t as easy to reach and sometimes don’t feel as secure to me. Another usability feature that this Bulls model offers that some of their others do not is the larger CI backlit display panel. Being larger, it’s much easier to read from afar and I absolutely LOVE that it’s removable. This will reduce instances of scratching and wear from sun and other weather when parked at the rack. The display even has a little Micro USB port at the bottom for charging your phone or other electronic devices. I sometimes use my phone for GPS directions so that’s really cool.

In terms of performance, the Brose motor is quiet, responsive and very efficient if you simply switch gears naturally as you ride (lower gears for climbing, higher gears for going fast). Inside the motor are gears to transform high RPM into powerful torque and you can hear some whirring as it spins but this is still one of the quieter motors out there to choose from (comparing to Bosch, Yamaha or Impulse). It doesn’t offer shift-sensing but that’s not as important since it uses a combination torque and cadence sensor and the drivetrain here is a geared hub vs. traditional derailleur with cassette. I like that both the motor and battery are low and center on all models of the Lacuba EVO E8 because some similar designs from competing brands opt for the rear rack battery which reduces your carrying capacity there and stands out more in my opinion while also shifting balance and raising the center of gravity. Accomplishing the preferred design here costs more but again, the price for this bike isn’t outlandish. Some minor improvements I would like to see however are the rubber flap that covers the charging port… It doesn’t stick down as easily as I’d like and could let water and dust in. The bike doesn’t automatically lock the battery in when you mount it and it would be a bummer if someone stole this because they are very expensive to replace. The key for locking the battery in is right there at the bottom bracket where the crank arms pass by and could easily get broken if you forget to remove it. I also feel like the Shimano Inter8 geared hub can be a bit wonky and take some getting used to, it doesn’t always shift immediately if you’re pushing down and this can cause confusion and over-shifting.

All things considered, this is a fantastic electric bike platform that’s at home as a very fancy comfortable neighborhood rider, a tuff urban commuter or even a touring or trekking ebike. There are solid electric bikes that offer similar performance for basic riding that cost half as much but this one will surely last longer and perform at a much higher level than those. Bulls offers an excellent two year comprehensive warranty along with five year frame coverage. They’re opening up more dealers in the US but have a solid global reputation from years of operation in Europe and Asia. From 2016 to 2017 they’ve introduced many more models and I can tell they are committed to delivering an excellent experience. That’s part of what you’re paying for here and why I’d strongly consider this model for my own commute in town. Just grab a nice pannier backpack or duffle style trunk bag and you’re set for 40+ miles of riding each day and impressively fast charging thanks to the 5 amp charger (most are just 2 or 4). It’s an electric bike that’s easy to get excited about and one that fits into the most widely accepted Class 1 category with 20 mph top speed in the US. Big thanks to Bulls for partnering with me for this review.

Pros:

  • The bike is extremely well equipped, the design is polished and it comes in three frame styles (stiff high-step, easier to mount mid-step and approachable wave deep step-thru) and five frame sizes!
  • In addition to a range of frame styles and sizes that improve fit, there’s also an adjustable angle stem and relaxed curved bar with name-brand ergonomic grips on this bike
  • At over $4k this isn’t what most people would call affordable but considering the internally geared hub, brand name belt drive, integrated lights, reflective tires and high quality rack with a mini-pump I think it’s a good value for what it is
  • Most of the super commuters and touring electric bikes I test out that have fenders, racks etc. all weigh a bit more but at ~56 lbs this one isn’t bad and part of that is the air suspension fork… internally geared hubs also weigh more but are durable so it’s a good trade-off here, the battery is easily removable for reduced weight when transporting
  • Belt drives tend to stay cleaner than chains because they don’t require lubrication, they also run quiet and don’t drop (in part because this is the upgraded Gates CDX with center-tracking design)
  • In addition to the cleaner belt drive, you get tightly integrated plastic fenders and a nice chain guard to keep your shoes and pants clean even in wet conditions
  • I love the rack on this thing, it has pannier mounting tubes along the sides, a spring latch on top, an integrated mini-pump and it connects to the fender for added support and reduced rattling
  • It’s great that they designed the downtube in such a way that you can still mount a bottle cage for easy-to-reach hydration while riding, consider a trunk bag like this for carrying extra bottles
  • I was really impressed with the battery capacity offered on this and other Bulls electric bikes, you really could use this for long commutes or touring, the efficient mid-drive motor is a battery sipper compared to hub motors
  • It’s nice having a display panel to show your speed, assist level and power output but I’m super happy with the one they chose because it’s removable… that means less wear and damage at racks outside if you commute (just don’t misplace it), I also like that it has a Micro USB charging port in the bottom for charging your phone or other portable electronics!
  • Solid hydraulic disc brakes provide smooth powerful stopping power and the levers offer adjustable reach so you can use them easily even if your hands or fingers are smaller and shorter
  • The bike is already really comfortable but you could swap out the rigid seat post with a 30.9 mm suspension like this, just keep in mind it will raise the minimum seat height, I like the Selle Royal saddle that comes stock (it’s a bit larger and less firm than others)
  • I like that the tires have a kevlar puncture-resistant lining because it’s not much fun fixing flats and only the front wheel has quick release here (because the rear uses an internally geared hub, you’ll need tools to remove the bolts)
  • The charger outputs 5 amps so it fills the pack quicker than some others (which are just 2 or 4 amp) and I like that they went with the fancier magnetic EnergyBus port because it just pops out if you trip over it vs. tipping the bike or bending the pins

Cons:

  • Activating the bike requires two steps if you haven’t ridden for a while, press the power button on the downtube then up at the button pad, could be confusing at first if you haven’t charged the battery in a bit and can’t figure out why it’s not powering up ;)
  • I love that the battery pack locks to the frame for security but feel that the key is positioned in a vulnerable spot where the crank arm can hit it if you’re not careful
  • It’s nice that you can charge the battery while it’s on the bike but the rubber flap designed to cover the charging port at the base of the downtube doesn’t stay down very well, I feel its design could be improved
  • The battery pack slides up into the downtube so getting it out can be a little tricky and definitely requires two hands, you have to unlock it then sort of pull down (but not so hard that it hits the fender or ground if you aren’t careful)
  • I like that you can shift gears while at standstill on this bike because it has an internally geared eight speed hub but for the gear to actually change I’ve found you can’t be pushing very hard… so when riding I back off a bit when shifting (especially when climbing)
  • The Brose motor system uses cadence and torque measurements to activate and is fairly responsive but does not have shift sensing, that’s less of an issue on an internally geared hub drivetrain like the Shimano Nexus Inter8 here

Court, I suspect that you don’t want to charge that battery with either port… I suspect the BMS only protects one side. I’m basing this on the experience that if your bms goes out you can reverse charge a battery still by rigging a cord for the other port.

Hmm, interesting feedback! Thanks for chiming in. I might have gotten some incorrect information or just misspoke. Would be good to confirm this with a dealer or as you suggest, just use the charging port that is exposed when mounted to the bike. That one is clearly going to work :)

Right… thanks, I do my best but there’s lots of room for improvement. I suppose that being around $5k+ ebikes regularly has had an influence on me and my language isn’t always on target (I do a little bit of editing before posting videos and stuff like this usually gets a second consideration). Here on the site I’ve got an “affordable” category that’s more rigid, the bikes have to be in the $1,500 range which I hope truly is “affordable” and not just “good value” ;)

Hey Court,

Great review, as always! A couple updates and information bits that pertain to all the BULLS Brose mid-drive eBIKES.

  1. New software updates for Brose include a “wake” function, which means the bike can be turned on and off at the handlebar display control, in addition to the downtube.
  2. Which I mentioned in a previous reply is that the battery can be charged from either port. As you correctly assert, one plugs into the bike while inserted. The other allows charging to occur while inserted.
  3. The key is not necessary for reinstalling the battery, as long as the lever is in the open position. Typically this would be when the greatest risk for getting the key stuck or broken off would be.

Hope this helps clarify.

Court, Your review of the Bulls Lacuba Evo E8 was most informative. I am a newbie to ebikes, and trying to learn all I can. Your technical reports are a big help in teaching us about the pros and cons about the different ebikes. My wife and I are senior citizens in our seventies, and I believe the Bulls Lacuba Evo E8 seems to be the bike for us. We will be riding where there are some long grades in the high country. Question: If need be, can it be ridden with motor power only, or does it require some constant peddling? Keep up the good work. Regards, Rusty

Hi Rusty! I sure do like the Bulls Lacuba E8 but it does require constant pedaling because it’s a Class 1 Pedal Assist bike vs. Class 2 which has throttle. BionX makes an excellent line of motors that have a throttle mode and you can buy them pre-installed on bikes from OHM and others, check out the OHM Urban XU700 here. It’s an awesome bike with the same step-thru frame… the company offers a good warranty and is a bit bigger and more reliable than some. Biria also makes a deep step-thru with the BionX system and I just finished reviewing theirs here. I hope this helps you out, sounds like you and your wife will have a great timeout there on bikes again and the electric motor should help flatten those hills ;)

Your written write up states the Bulls Lacuba Evo E8 2017 has a 350 watt motor. Is that true or is it a 250 Watt motor?

  Reply
Court Rye

Hi Sanford, great catch and I do apologize for the inconsistency between my writeup vs. the specs, I’ve fixed it! In short, the motor ranges from 250 to about 530 watts depending on power level selected and the signals being sent (pedal torque and speed). I think I made this error because the Brose system reminds me of Bosch in many ways which officially says 350 watts nominal but they use the exact same hardware as in Europe where it’s rated 250 nominal. Sometimes I feel like it’s marketing more than reality given the range of power possibilities. Hope this helps! The Lacuba is a solid choice but there are other drive systems out there worth exploring if you’re concerned :)

Hi Court. I live in a level area near the beach. I want to take advantage of a new bike right of way along side a new light rail extension very close to home. Should I therefore avoid 28 mph ebikes? I’m 68 yrs. old and am also a bit concerned about crashing while going 28…I test rode a 28 mph model recently and it did seem a little hairy going that fast along side traffic on regular streets. Do folks regret gettiing a 20 mph model such as this model Lacuba after they’ve become accustomed to riding an ebike and then wishing they bought a faster model? I’ve enjoyed your reviews very much. Thank you for any comments.

Hi William! I have only ever owned 20 mph ebikes myself and never felt like I was missing out. For me it’s important to blend in, avoid breaking any rules (since I’m kind of a public figure) and be an ambassador for the space. I still really enjoy riding my unpowered bicycle and feel like that can be fast! If you’re someone who loves speed, needs to get to your destination as fast as possible or want to gain respect from cars (some people feel like if they ride the same speed as cars they aren’t challenged as much) then speed pedelec might be the way to go. I think it makes the most sense for people who ride on the shoulders of streets… You can ride them slower btw, it’s not like it forces you to hit the top speed. I just tend to get Class 1 ebikes since they are more plentiful and I ride on bike paths and occasional mountain trails. Hope this helps!

Hi Court, great review as always. I really enjoy your reviews on ebikes, you’ve helped me a lot learning about them and I’m gonna buy my first ebike this summer, it’s looking like it might be this one! I just have one question first. How are the gears on this bike when pedalling without electric assistance? Maybe you could give a comparison to another ebike and a regular bike? I don’t have a place where I can try this model out and I’m probably gonna be biking a bit without electric assistance as well so I’d like it to be at least decent. Thanks in advance! /Albin

Hi Albin, the eight-speed internally geared hub doesn’t shift as fast and hard as many traditional derailleur sprocket combinations but it won’t mash, come out of tune or get as dirty either. At ~56 lbs, this isn’t one of the lighter ebikes but it’s also not bad considering you get fenderd, rack and a suspension fork… if you added those options to another ebike it would probably weigh similar if it had similar specs. I really like the Lacuba EVO E8 and appreciate belt drive systems in general. The belt doesn’t bounce around or come off as easily and you with that eight speed, you can definitely pedal the bike unpowered just fine, the tires are efficient and the fork locks out if it is bobbing up and down and you want to conserve as much pedal efficiency as possible. I hope this helps to answer your question, I realize test riding before buying would be ideal but this is a high quality product. If it fits your budget and delivers the features you want then I think you’ll be happy with it. The Brose drive system is awesome and I like how clean the battery integration is here.

Hi Court,

This is my leading choice. I am intending to do long distance touring. My current bike is what you call a mid-step frame. With the mid-step, on days where I am on and off the bike a lot, I sometimes get hip pain. Do you think the wave model has too much flex for a long distance tourer? (Rider + Gear = 250lbs+)

Also in comparison to the Bulls Cross E with the Bosch system, would you still rank this as a good value? Do you think there’s enough to justify the additional cost of the Lacuba Evo 8 for a tourer?

Thanks.
Johnny

Hi Johnny, I think both could work well and although there’s sure to be a bit of frame flex, it’s not a deal killer at all. They are designed with balanced battery positions (even the rear rack battery on the Cross E). The battery capacity on the Lacuba EVO E8 is greater and I think Bulls is smoother and maybe more efficient thank Bosch in this case? If you go for the Cross E, I’d probably recommend getting a second battery pack. Depending on how far you plan on going, definitely bring your charger with and both have faster chargers (Bosch 4 Amp and Brose 5 Amp here). I think your interest in the Lacuba Evo E8 is spot on and would probably be my first choice given what you shared. I’d love to hear back about your real-world experience if you go this direction!

I bought an LACUBA EVO E8 WAVE 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.

Discovering electric bicycles changed all of this, I was introduced to the EVO E8 and found that its 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 an unsettling experience. While ‘testing’ the bike downhill on a paved road, reaching about 40 k/h (not pedaling) the bike started to wobble. Only thanks to the experience I have riding bicycles, I was able to stop it safely.

I contacted the store, having decided to return the bike. They were 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 again which was frustrating.

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. 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.

Sincerely,

Thanks for sharing your thoughts, the steps you took, and how you were able to recreate speed wobble on the BULLS Lacuba EVO E8. I have experienced this phenomenon, or something similar to it, on many ebikes that have rear-rack batteries such as the MOAR eBikes 24/7 prototype. It can indeed be uncomfortable and perhaps even unsafe depending on how you ride. I think it has to do in part with the bike setup but also the rider weight distribution. The Lacuba EVO E8 offers lots of adjustability at the stem and seat-tube… plus, it comes in three styles (high-step, mid-step, and wave). There are probably specific size/style/geometry setups that are more susceptible to speed wobble and perhaps the bars can be sensitive with those setups and at certain speeds due to resonance, but the demo bike felt decent to me. I’m not sure this warrants a recall but I would advise you and anyone who rides the bike (or any bike) to really get to know how it handles and ride safety with protective gear. By the way, speed wobble can also happen on skateboards with looser trucks (especially at speed), I think that tightening your suspension probably helped… I’d be interested in the frame size, style, and your weight to help others who might be considering this bike.

Thanks for your comments. I am very happy I got involved in this forum. I wish the circumstances would’ve’ been having a different tone. The Lacuba I have is the Wave model. This model has the lowest ‘step-through’ of any model. Due to my physical limitations, I cannot ‘mount’ a bike, a horse, donkey, motorcycle, or anything that requires ‘mounting’.

Buying this bike/model was a long process since I wanted to actually try it and compare with other brands/models. What I mean by ‘to try it’ is actually to ride it for a couple of hours or so, to get a true feeling of it. This was not done in a ‘city kind of environment around the block from the store’, but a place with hills, rolling roads and so. I fel in love with its comfort. It was exactly the kind of design for me: I can ride it like you ride an ‘urban bike’, perfectly sit with my spine perpendicular to the ground. With such a configuration, naturally, there is very little weight/force on the handlebars. I didn’t need to modify and/or adjust the bike for some awkward position. I am riding it the way it is supposed to be ridden.

I am 5’7″. Yes, I recognize, I could be lighter but it’s within the specs of the bike. 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 Bosxter, 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?

Cheers,
Alberto

Hi Court, Thanks for the excellent review as always. My wife and I are proud owners of a High-Step (58 cm) and a Wave (50 cm) as of 10 days ago. They are really fantastic bikes. I am 68 years old, 6’2″, and 203 lbs and the wife is 67, 5’6″ and 180 lbs (shhh). We’ve ridden them with lots of assist since we like to cover more trails and enjoy peddling but don’t want to effort up the numerous hills in the Denver area.

On flat ground with slight inclines here and there, we found level 2 and gear 6 makes it feel like we on a slight down grade all the time. Up the steepest hills, we use level 4 (now has “0” and 4 levels of assist) and 3rd or 4th gear so we don’t effort at all. Really, really fun!! I know it’s not healthy to fully drain even a Lithium-ion battery but I wanted to use mine until it quit to see what kind of mileage we would get given our moderate assist riding averaging 8-10 mph. At 47.5 miles, the final bar of battery charge started flashing and at 48.5 miles the assist quit. That was quite impressive considering about 10% of the driving was on a gravel/dirt canal trail.

We added a basket on the back of my bike so we could take our 15 lb mutt. He enjoys it as much as we do. Just a note; I rode my wife’s “Wave” model bike trying to induce the wobble mentioned above and could not replicate it. I personally don’t see an issue. It worked flawlessly. We’ve change the seats out for 2, more age appropriate, softer and wider seats plus have ordered 2 Thudbuster suspension seat posts (short travel). They will be here in a few days.

Here’s what we like best about our new bikes:

  1. They don’t look or sound like an E-bike so we go anywhere we want without issue so far.
  2. Very, very quite especially with the belt drive. In fact, we can’t hear any noise going 8-10 mph in assist level 2 and gear 6. More quite than a regular bike with a chain.
  3. Mid-motor drives mean greater range than a hub motor plus it has large battery capacity (647wh).
  4. The gears are leveraged with a mid-motor drive so we can climb amazingly steep hills in the lower gears without straining the motor. Very nice when we ride the trail from Dillon to Aspen uphill then coast back.
  5. Fast charging time with the 5 Amp charger that was standard equipment (instead of the usual 2 Amp).
  6. Better warranty than with other bikes we were considering.

Safe biking! Jim

Wow, what a fantastic overview James! You included all of the relevant details about body weight, model type and size, and even your age. This is incredibly helpful and useful. I grew up in Colorado and can just imagine you and your wife out there having a blast together in the beautiful mountains and sunshine. Thank you so much for this feedback and the list of things you appreciate about the Lacuba EVO E8, it means a lot to me and other readers I’m sure :)

I bought the diamond frame 53cm Lacuba evo 8 two weeks ago and have ridden 75 miles so far. The things i love are the battery range, assist levels, very clean machine, quiet, and might i add good looking. I am 66 years old and weigh 250#. This is the 5th ebike I’ve owned. The first one i bought a kit and transformed my tadpole trike. Then a cargo bike that just did not work out. After that 2 easy motion bikes that were really nice. (neo cross and evo city) I wanted this bike for the range because I was tired of recharging the battery every other day as I use the bike like a car.

Had the bike up to 32mph with no vibration problem. The only complaint so far is that little battery release knob that traps my pant leg and requires me to roll up my cuff prior to a ride. I also switched out the seat for a firmer smaller seat. Oh, I forgot to mention the lights and control system. They are great.

Hi Tom, thanks for the wonderful update on your Lacuba EVO E8! You sound like quite the ebike fan, very experienced and full of good information. That point about snagging your pants on the battery release lever is a good one. I have experienced similar things with quick release levers and bottle cage adapters… it’s frustrating. I feel that the battery interface from Bulls for the Brose battery design could be improved, like the charging port cover rubber thing, it just doesn’t seat as well as some other designs from competing companies. Anyway, I’m glad you like the bike, thank you for sharing your range and including your age and weight, I’m sure it will help others who are also considering the bike :D

Having a very tough time choosing between the EVO E8 and the Cross Lite E. I ride in Chicago, usually along the lake front path, 10 miles to work each day. Some days, the wind is a bit much, but the ride is almost entirely flat. I’d guess either the Cross Lite or the EVO will get the job done, but do you have a preference for either? The belt drive associate with Brose sounds like it might be a better option for inclement weather, and salty streets during wintertime, but I can’t really tell from the photos which cycle will be easier to keep clean and maintain. Any advice?

Hi Lou! The Cross Lite E is going to be sportier, the body geometry and even the saddle are setup to make your body slightly more aerodynamic vs. upright. I love the Bosch drive system and especially appreciate how well the battery and motor are integrated on the Cross Lite E but the battery capacity is smaller, the motor is going to be louder and zippier feeling, and you won’t be able to angle that stem up if you want to. One consideration is the 7 lb weight difference, if you need to lift it, the Lacuba is heavier and does not have two quick release wheels. I would buy the Cross Lite E for myself, I don’t care that much about belt drives… but you make a great point that it will be quieter, require less maintenance, and probably fare well in cold wet environments. I think both models could work for you but I’d probably choose based on body position and availability of the right size. I hope this helps you out!

Hi Court. I was told by a very reliable source who is in the know that there’s something seriously wrong with the belt on this model. Something about incorrect length which causes the belt to snap well before it’s meant to do so. The manufacturer is apparently addressing the issue with their 2018 model of this bike. Furthermore, the position of the battery lock/key for the 2018 Bulls ebikes have been moved so no danger of them sheering off by accident.

Thanks for the update! I’m glad they are making the necessary adjustments to improve the lock/key setup and while I didn’t experience the belt orientation issue you describe, I appreciate the insight and hope it’s not impacting too many riders :/
