Written Review

Plus sized tires are becoming increasingly popular for electric bikes. That’s because they improve comfort a bit, increase your contact patch size resulting in better traction and they disperse some of the added weight that a motor and battery produce on the frame. I suppose they would have become popular more quickly with traditional pedal-powered mountain bikes except for the added drag and weight. With an e-bike, you’ve got electric assistance that more than compensates for a bit of drag and thus, more bikes are turning to these tires as a sweet spot between 2.25″ and the much larger 4″ fat tires often reserved for sand or snow riding. With the E-Stream EVO FS 3 27.5 Plus you get 2.8″ wide plus sized tires whereas some competing bikes are opting for full 3″. I found these to perform similarly, perhaps they’re slightly lighter due to the lower volume of rubber? Another unique quality of the wheels on this bike are that the hubs use Boost technology which is to say, they are slightly longer. This allows for steeper spoke angles and a stronger more sturdy wheel as a whole.

Okay, with all of that tire and wheel stuff behind us, let’s chat about the drive system a bit. One of the coolest aspects of the Brose powered models from BULLS this year is that the battery pack and motor are extremely tightly integrated… nearly disappearing into the frame. This is a beautiful looking, well balanced and QUIET electric bicycle designed to Class 1 specifications, meaning it only assists up to 20 mph and does not offer a throttle. In many parts of California, that means you can legally ride it on mountain bike paths. It’s perceived as a human powered cycle first because it uses a combination of wheel speed, cadence and most importantly, pedal torque activated operation. Laws aside, what I found was a super-responsive mountain bike that felt comfortable even when riding near steep cliffs, as I did in the video review above. In this type of terrain, you don’t want a clunky or slow-to-react drive system because it could take you past the mark resulting in an accident.

The Brose motor used here offers a whopping 90 Nm of peak torque and a range of 250 to 530 watts power output. At high cadence, you can hear a pronounced electronic whirring noise but I’d consider it one of the quietest mid-drive systems on the market right now. This is due in large part to the addition of a belt link inside the motor case that reduces vibration. I’m only guessing but this might help to extend the life of conversion gears and as a rider, it does create a smoother feel than say, Bosch. Now, I’m a huge fan of Bosch and BULLS offers this drive system on many of their other mountain models… but it’s a lot zippier and the chainring is limited to just one sprocket. A huge differentiator with the Brose motor is that multiple chainrings can be used and in the case of the EVO FS 3 Plus, they opted for an 11 ring cluster in the rear with two rings up front. The shifter and derailleur hardware is higher-end Shimano Deore XT Shadow Plus and although the motor does not offer shift sensing, I had no problem shifting without much mashing when I adjusted my shifting behavior a bit… making sure to ease off the torque pressure and thus, deactivating the motor before shifting.

This is a really fun and capable all-mountain electric bike. It has longer handle bars (as it should) locking Ergon grips for stability, a four-bar link suspension with quality RockShox components and the’ve even managed to squeeze in a bottle cage mount. One thing I’m not super fond of is how the battery pack locks in and charges on the bike. While I love that Bulls opted for the EnergyBus magnetic charging interface (that reduces bent pins and tipped bikes if tripped over) I don’t like the little rubber cover that’s used on the frame. It can be difficult to force into the charging port hole when not in use and I just feel like more dust and water will get in as a result. Also, you have to manually lock the battery in after clicking it onto the frame. It’s like a two step process where you use a keyed slot for locking the battery and a separate slider rod for disconnecting and taking off the pack. Perhaps this was intentional as twisting a key while holding a battery requires more finesse vs. sliding a rod while holding a battery… but in both cases you need to be extra careful not to drop the battery and in the former, if you leave your key in and forget, then later move the bike backwards the left crank arm may collide with and bend the key! It’s all just a little cramped and tedious. But at least it looks good, secures the battery properly and I like that they included foam pads on both the motor casing and battery case base to deflect rocks and other debris.

Having used this bike a bit on true mountain terrain as well as the popular Specialized Turbo Levo which also uses the Brose motor and has plus sized tires… I must say I enjoyed both. Priced at $4,699 I find the Bulls option to be quite tempting. And although they are somewhat new to the US market, their reputation in Europe and Asia is good and their warranty is reassuring. You get two years comprehensive and they are opening more and more dealers each year. My final thought is that it’s great to have a wider range of size options on this and other e-mountain bikes. This thing isn’t super light at ~54 lbs, nor is any other full suspension higher capacity build. Not having to worry about a frame that doesn’t fit or one with an unnecessarily high stand over height is nice. I appreciate the sloped top tube here and the overall stability of the geometry. Most of all, I just think it looks great. Big thanks to Bulls for partnering with me for this review.


  • Available in four frame sizes for improved fit and comfort on longer rides, the top tube is angled as much as possible while still affording a vertical rear shock (lower weight distribution along with the battery and motor)
  • The electronics on this bike are extremely well integrated and hidden, the battery mounts up into the downtube, the motor completely replaces the bottom bracket with a custom interface and even the display panel is small and unobtrusive (just a toggle switch with little readouts) most wires are internally routed across the frame
  • The slightly larger 2.8″ wide tires offer more cushion, better traction and less deflection which makes them fun to ride on trails and mountainous terrain, the Schwalbe Rocket Ron model is designed with thinner sidewalls to reduce weight and are tubeless ready for further reduction while also permitting low PSI without “snake bite” tube punctures
  • Amazingly, despite the main triangle being mostly occupied by the rear suspension and tighter area due to the sloped top tube you are able to mount a bottle cage or other accessory using the bolts on top of the battery
  • Longer travel 150 mm suspension fork and 15 mm thru-axle makes this a great candidate for enduro and all-mountain riding, the rear 150 mm suspension is also solid with some adjustability on stiffness and you get a 12 mm axle there… both are quick release for easier maintenance and transportability
  • You get 22 gear combinations here with quality Shimano Deore XT Shadow Plus components, if you’re climbing a lot this comes in handy and the E-Stream EVO FS 3 27.5 Plus is one of the few mid-drive full suspension ebikes I’m aware of with that many gears
  • The Brose motor is very quiet and smooth thanks to a belt interface between the gearing parts that reduces vibration… I also found that it was responsive and quite powerful
  • I appreciate the upgraded touch points including locking Ergon grips and comfortable Selle Royal Seta M1 saddle
  • MT-4 and MT-5 hydraulic disc brake calipers from Magura (two and four piston models respectively) offer great stopping power, both rotors are 180 mm diameter for dispersing heat
  • The wheels are built with “Boost” which means they have longer hubs that allow for a stronger spoke angle and stiffer handling
  • Both the battery and motor casing have a layer of foam padding on the base for protection against rocks and gravel flying up as you ride, it’s not as tuff as some other BULLS ebikes with metal scuff plates but also doesn’t weigh as much
  • Despite being so small and compact, the toggle button / display panel thing near the left grip has a built in Micro USB charging port so you can power your phone or other portable electronic device!
  • Impressive two year comprehensive warranty, 1,000 full cycles on the battery and five years on the frame… this is a larger more established company with good support


  • Be extra careful when keys are inserted into the battery lock as they are directly in the path of the left crank arm (which rotates backwards if you roll the bike backwards)
  • The battery comes out downwards from the downtube and while it’s secure once unlocked, if you’re pulling down to remove it there’s a bit more force at play due to gravity and that makes it easier to drop or mishandle
  • This is one of the only bike designs I’ve seen with a battery that can be clicked onto the bike but not locked (you have to purposefully lock the core using the keys), a secondary slide mechanism unclips the pack
  • I feel like the rubber flap covering the charging port on the lower left are of the downtube could work better, it doesn’t fit into the charging hole very easily and this means dust and water can get in
  • There’s no shift sensing technology on the electric bike drive system and considering you get 22 gear combinations, that means you’ll have to be extra thoughtful about how and when you shift, it’s torque sensing so just get up to speed then ease off while shifting before applying more pressure
  • I’m not sure this bike comes with a slap guard? Consider adding a neoprene wrap or sticker (even clear tape) to avoid chips on the right chain stay
  • Good combination of rolling momentum and quick handling with the 27.5″ wheel size here, I’ve found that they also don’t clip my toes as much as 29ers
  • Given the longer travel suspension I was surprised that they didn’t add a remote seat post dropper, this kind of thing is very handy when you start to do more downhill riding and the bike is priced pretty high so it would have been nice if it was included, here’s a solid dropper that would fit the 30.9 mm diameter of the bike for consideration

Hi Court! Just curious how much effort is it to pedal this and other similar weight FS MTB e-bikes at or above the 20 mph motor assist cut-off point? In other words, do you need “pro cyclist legs” to reach and maintain higher speeds (i.e., say 21 to 25 mph) on flat paved surfaces with no head wind pedaling in the highest gear (for this bike = 3.5 gear ratio) assuming pedaling at a high cadence (above 100-120 RPM)?

Hi Pete, in my experience it is very difficult to top and consistently maintain even 20 mph on flats with calm air if the motor is not supporting you. The added weight and friction of electric mountain bikes is a limiter. There are some eMountain bikes that have Class 3 drive systems which can hit ~28 mph but they are rare. This is just my experience and I haven’t focused on it as much as I should… I’d love to hear your experience if you can get out and test the theory. I regularly top 20 mph but it’s usually on downhill sections.

I got this bike – E-Stream EVO 2 (hardtail). Here’s the good, the bad and the ugly.

The good: The bike is heavy, no doubt. Without assist, this moves like pulling a boat away from the dock with a rope in your teeth. Turn on the assist though and this bike is NIMBLE – moves like a dream! I love the fact that this has a huge 650 watt-hours battery, one of the largest I’ve seen. At level three assist, (4 is the max) in hilly territory, I am able to get 15 miles out of each bar. With 5 bars, this should get me 75 miles. Of course, I don’t like to shave it that close. As I mentioned, if I ever run out of juice it’ll be like towing a boat overland. But I’ve gone on a number of 45 mile runs and come back to base with two bars of juice left on the battery. The motor is silent and lends such a natural and smooth assist to your own effort. This bike makes biking fun again!!!

Here’s the bad and the ugly. HUGE design flaw, embedding the battery in the *bottom* of the downtube. Just this past Monday I locked in the battery and set off on a ride. I didn’t get far when I hit a bump at 20mph and CRASH, the battery just dropped out of position. Now the battery is dead and it’s my word against the dealer. I say I locked the battery in place, the dealer says no – user error. Not sure where this is going to go, but these batteries are $950. Not too happy right now…

Suggestion for manufacturer:

  1. For a minor bit of added engineering, you can ensure that the battery not make contact unless it is properly locked into position! This would clarify the point for every rider. If the battery is providing power, it’s locked in, otherwise it’s not.
  2. Why not embed the battery on the *topside* of the downtube? (Most e-bikes, even stealth bikes, do it this way.) This would add a measure of safety since gravity would work together with the locking mechanism to keep the battery in place.

Once I get back on the road, I am going to use a couple of velcro straps to augment the locking mechanism to make sure that, if the battery drops out of place, at least it won’t smash against the pavement.

Ouch! Thanks for tactfully sharing your difficult situation Yossi, that sucks. I didn’t drop any batteries during my tests but I did feel that the interface was overly complex. You have that slider lever and a keyed locking core… I noticed that I did not have to lock the key in order to mate the battery, and this would let people potentially just unlock and take the battery (or maybe allow it to clunk out easier as in your situation). The charging port cover is also a bit finicky. Definitely room for improvement… but it looks like Bosch is also going for the under-mount approach with their upcoming Powertube design. For me, it’s difficult to bend down and pull the battery out this way vs. lifting up. So yeah, I like how Specialized did it with their Turbo Vado which also uses a Brose drive system. I guess Brose allows each manufacturer to set their battery up however they want.

In all fairness, I should mention that the question of warrantee isn’t entirely up to the dealer. The dealer is a nice guy, and he’s trying to work it out but given the fact that the case is a bit banged up, he doesn’t feel that there is any chance of getting the manufacturer to honor the warrantee. That being said, the dealer is trying to work with me, to revive this battery, either with assistance from the manufacturer, perhaps they’ll recondition the battery for me for a fee, or as a last resort, perhaps we’ll open the case ourselves and hopefully find some loose connection which can be easily fixed. If anyone wants a good dealer in the Hudson Valley area I could name him, but I don’t know if you allow that level of blatant commercial ‘advertising’ on this forum?

Anyway, the hit to the battery stings, but I am having tons of fun on this bike. (I am mobile again because I had already ordered a spare so that I can do centuries.) I would encourage Bulls to tighten up the engineering of the locking mechanism to prevent activation unless the battery is firmly locked into place. This would be a low-tech mechanical solution with a huge bang for the buck for consumers.

Just a follow-up to say that I’m getting ‘radio silence’ from both the dealer and the manufacturer on the question of whether I can get the battery replaced under warrantee or at least repaired. It was all smiles when I was shelling out the $4,500 for the bike and the extra battery but where’s the support???

Hmm, that’s a bummer Yossi, maybe Bulls will reply or be more available to help now that Eurobike and Interbike have ended. Try reaching out again, some dealers even go to these events and can get distracted. I just got back myself and have been behind on emails

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

It was the big swedish retailers showing of 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.

I have never ridden or even seen one. But since Bulls was formed by a cooperative of bicycle dealers, it does not surprise me that they would know how to design good bikes. That said, I know there are other good bikes too. The question should really be, what is the best e-bike for you?

Just got my FS 3 and wanted to add kickstand too. Do you have some pics how did you installed that stand. Did you add some clamp?

Love the bike though. It's my 2nd ebike. My other is juiced bike I used as commuter.

6 months ago

I'm using a Felt Massload CL-KA89 kickstand on my Bulls E-Stream Evo FS 3 27.5 Plus.
I think it's made to fit on Felt Lebowske or Outfitter bikes. ($24)
It requires the 2 threaded mounting points built into the frame just forward of rear axle.

Has anyone tried using the mini USB charging port on the Bulls controller to connect an iPhone? What type of cable have you used? I tried an Android OTG (On The Go) cable connected to a regular lightning cable and it didn't work. I have not been able to find a mini USB to lightning cable of any length available in Canada. If anyone has a source, please provide a link!

BTW, this is for a Bulls E-Stream EVO FS 3 27.5 Plus which I got a month a go. Will be providing a full review after a little more saddle time. Spoiler Alert: I haven't stopped grinning since I got it!

I have those versions above and i'm looking to find the difference: Mine is set up in kmh and has a limit of 25kmh. I would like to find out if I can set my bike up with the US-Version im mph with a limit of 20.

Court-Outstanding review! Love BULLS bikes. Looks like this is a better buy compared to the Levo you mentioned at a much better price point. I think you are getting more bang for your buck being the Levo is more in the $7500 dollar range. Do you agree? Also, when you are riding at this location, it looks like you are getting awful close to the cliff drop off, or am I being too critical concerning your safety? Be careful Court!!

Propel Electric Bikes

Court actually has the Levo. We spoke a bit about this. I think you might pay a slight premium for the Specialized brand. I think the Bulls might be a slightly better value if you were to compare specs.

I like the look of this one. Quite a bit pricey mind compared to what companies like Haibike can offer. Though I prefer the look of this one over the Haibikes. I have a AllMtn SL which was around £2700, which is quite a lot cheaper than this one. It too has 150 mm of travel, though I suspect the components arnt as good "quality".

In my opinion nothing beats mid drives for off-road though. A mid drive will give you much more control and you have the mechanical advantage of using the bikes drivetrain.

Court, your are a video review churning machine! Keep up the great work. I really enjoy hearing your input on e-bikes. Please keep the 2017 Raleigh Redux IE (also with the Brose) on your list of bikes to test ride. I don't think dealers have them in stock yet. But their price point is a little easier to stomach than $4500+ on these Bulls.

BTW you filmed right next to our firehouse when you were in Brooklyn. Stop by and say hi next time you're in the hood. ;)

Court, are you going to do a review on the other Bulls bike you mentioned in this video? I heard you say it shares a lot of the same components as the EVO FS 3 27.5 but its a speed pedelec. I love the design and over all look of these Bulls bikes and how well they integrate the battery. I know I've said this many times before BUT I really wish these bikes had a throttle and the ability to hit 30+ mph. I need a bike to fit ALL my needs and this bike has that potential.... Bulls should offer these features as an option, I'm certain they can do it. As always, another good review. I appreciate your detailed reviews.

Robert, maybe you should make such mods. to your own Bulls ebike. Most likely propel and others have already done this but its not feasible to bring it to market. Too many issues, after all this is America, the land of litigation.

We've had these sort of requests before, but we're not going to do that. I think overtime we might see more throttle activated bikes like that, but their going to need to be registered as mopeds in most jurisdictions.
