  • An enduro style full suspension electric mountain bike with longer 160 mm suspension travel, seat post dropper, 27.5" wheelset and premium hydraulic brakes
  • Downtube-integrated battery pack is out of sight and keeps weight low and centered across the frame but is not easily removable, it takes 30+ minutes to unscrew the frame, this means the bike stays heavier and the pack might get hot/cold vs. storing it separately
  • The mid-drive motor is made by Brose, it offers "trail tune" performance with higher 90 Nm torque output and is very compact and quiet, you start to hear it at higher RPM but otherwise it looks and sounds great
  • Available in two frame sizes (both offer the same high-step build and black with white and blue accent color scheme), I like the small transflective LCD control pad, it's easy to reach, simple to use and highly visible

Written Review

The Bulls E-Stream Enduro is a downhill oriented electric bike utilizing the highly-integrated Brose mid-drive motor system. While it’s positioned as top of the line, you might also consider the FS 3 which offers the same 27.5″ wheel size and 160 mm travel with less aggressive rake. This translates to cross country riding vs. enduro which is a racing style that includes uphill climbs and steeper “downhill” descents. I demoed the Enduro model at an Electric Bike Expo event in Denver Colorado and was able to cruise around the parking lot, take on some rocks and climb/drop a steep grassy outcropping. Not exactly true enduro riding but it offered some time with the bike and reps to get to know the systems. In my opinion the Bulls Enduro performed great and reminded me of the Specialized Turbo Levo models which also use a trail tuned Brose centerdrive. The big differences were frame geometry, narrower 2.35″ tires vs. 3″ on the Levo, a more traditional bar mounted LCD button pad combo vs. downtube mounted buttons and an LED light readout on the Levo and a fixed non-removable battery on the Bulls. I liked the LCD display (especially with its transflective easy to read technology) but didn’t hear anything about an app so there were definitely gaps in the information being offered by the bike (like odometer, trip meter, range estimate). The biggest trade was having a fixed battery… I didn’t get to weigh it directly but at ~7 lbs this makes the overall frame heavier during transport and limits your charging options. You basically have to bring the entire bike inside or near an outlet to fill it up. And if you decide to leave it in your garage in hot summer months or cold winter ones the cells might degrade more rapidly than if the pack was kept separate in a cool dry location.

Performance wise, the bike rides great with high end components from RockShox and Shimano. I especially like the hydraulic disc brakes with quad piston pads and integrated heat sinks… This is important for actual downhill riding, especially given the heavier build of the bike vs. a carbon fiber non-electric. Depending on where you live, Class 1 ebikes like this (offering pedal assist only, up to 20 mph) may or may not be allowed on trails. In my experience, regardless of laws, the less noticeable your bike is the more accepted you’ll be and judged on behavior vs. hardware. When I first tested the Brose mid-drive in 2015 I had some complaints around lack of shift sensing but the compact design and quiet operation have since won me over. Unless you’re spinning at a high speed, the motor is very quiet and almost completely obscured behind the 38 tooth chainring. I love that Bulls has included an e*thirteen chain guide to clear mud and reduce drops (and possibly chain slip) but was surprised that the demo model I tested only had 10 sprockets vs. 11 listed on their website. 2015/2016 is their first year selling this and other models in the US. With a two year motor/battery warranty and five on the frame AND a longer history of operation in Europe (the company is German), parts of Asia and Australia, I felt that the quality of the components and build would also be reflected by good support. One area of opportunity, aside from battery removability, might be wire management. As it stands, wires are run along the top of the downtube vs. internally and you may or may not be able to add a bottle cage here which would be nice.


  • Extremely stealthy, the battery pack is integrated into a slightly larger downtube and the motor takes up the bottom bracket space without being oblong or extending much beyond the chainring, the bike could go unnoticed more than some other mid-drives like Bosch or Yamaha
  • Smooth and quiet, at lower RPM levels the motor hardly makes a sound, I did hear it pick up when I shifted way down and began spinning but otherwise it was one of the quietest ebike systems around (for this and other Brose powered bikes)
  • The motor relies on cadence and torque sensing for activation so if you push harder you get more back and it’s not as on/off feeling as Bosch, in some cases it feels less powerful but the 90 Nm torque rating is pretty impressive and it climbed well for me in lower gears, it’s responsive so the chainring stops spinning quickly after you stop pedaling (no brake lever motor inhibitors required here)
  • I love the display system used here, it’s small but easy to read with a special “transflective” LCD readout showing your speed, assist level (1-3) and battery capacity
  • An aftermarket chainguide was added to clear debris and keep the chain on track, it looks like a TRS or TRS+ model from e*thirteen
  • Durable battery integration, BULLS says it’s rated at the battery is rated at IP56 against water and dirt which isn’t as high as the Specialized Turbo offering IP67 (using the same drive system) but still better than no rating at all
  • Tight tolerance on the battery pack alignment and locking system, you don’t hear it rattling around at higher speeds off-road but you also can’t easily take the pack out so this makes sense
  • It’s available in two frame sizes to improve fit (43 cm and 46 cm) but only one color scheme and only in high-step (but the top tube is more angled so stand-over isn’t extreme)
  • Excellent weight distribution, the motor and battery (which make up at least 14 lbs) are both mounted about as low and centered as possible since they’re integrated into the frame design
  • For a full suspension electric bike with 36 volt 14 amp hour battery this thing is fairly light at ~50 lbs, you should get solid range due to mid-drive efficiencies if you shift properly and use the first two levels of assist
  • Great Shimano Saint hydraulic brake setup with extra large 203 mm front rotor and heat-sink calipers designed to deliver consistent stopping power even in long downhill situations
  • The tires come tubeless ready so you can set them up to ride at lower pressure and avoid pinch flats, Schwalbe Hans Dampf offer durability and the 27.5 wheel size is a nice trade-off for downhill and cross country riding… in my opinion this isn’t a true downhill-only ebike and I like that it’s a bit more versatile vs. something like the Haibike XDURO DWNHLL Pro
  • Aggressive fork angle and enduro geometry with long travel 160 mm suspension so you can take bigger hits when descending rough terrain
  • Thru-axles on both wheels with quick release so you can perform trail maintenance more easily or reduce weight/size for transport (15 mm front and 12 mm rear), the axles also help you line up disc brakes more easily and provide stiffness when riding off-road
  • I like that the display kind of clicks so you can get feedback even if you’re not looking down at it while adjusting, it’s easy to reach and there’s a built in Micro USB charging port for maintaining your phone or other portable electronic device


  • The Battery is not easily removable, you have to unscrew bolts to get it off verses just using a key or tool release system like with most other ebikes (including the Specialized Turbo LEVO which uses the same drive system from Brose) this means you have to bring the whole bike near an outlet to charge it and may end up exposing the bike+batteries to hotter and colder temperatures in a garage which isn’t as good for them
  • The display looks great and is easy to use with a tactile click up or down but isn’t large enough to show Odometer, Trip distance and some other sub menus like estimated range that appear on Impulse, Bosch and other systems with large consoles
  • Offers 10 gears vs. 11 or even 20 on some of the other mid-drive systems, there’s only one chainring to reduce weight, drops and complexity… I know the website says 11 but the bike I tested only had 10
  • While some of the other Brose powered ebikes have smart phone apps to help approximate range based on battery capacity remaining or your heart rate and even use GPS the Brose Enduro does not seem to offer one at this time, thankfully it has the basic readouts covered with a small LCD display
  • There’s no shift sensing built into the software or hardware (shift cables) as I’ve found on Bosch and Impulse drive systems, this could lead to more chain, sprocket and derailleur wear unless you’re conscious about how you ride (ease off when shifting gears, especially in the two high levels of assist)
  • The included battery charger is very fast but also a bit large and heavy making it less pleasant to stow in your pack, I like that it uses a magnetic Energy Bus interface
  • Quite a few of the cables and wires are exposed on top of the downtube, I saw a bunch of bolt heads towars the bottom where it meets up with the motor and seat tube and believe you might be able to mount a water bottle cage there which would be nice but am not completely sure
  • some of the specs recorded on the website were inconsistent with what I saw in person, most notably they said it was an 11 speed but I counted the sprockets at 10 on the demo bike
  • When you pedal really fast at a high cadence the motor produces a more noticeable kind of scratchy sound, most of the riding I did was very quiet however

Finally a review on a Bulls ebike! I’ve been comparing the full suspension Bulls to a Haibike. This seems like the better deal for the money. I do believe they make one with the Bosch drive as well in addition to the Brose. Looks like a nice bike. How did this soak up the bumps and curbs?

2 years ago

Hi Dave! Yeah, they do have a Bosch powered model with full suspension and I reviewed it as well (video/article coming soon). I like BULLS and feel that they offer good value similar to Haibike. I like the styles on Haibike a lot and the broad dealer network vs. BULLS which is newer in the US. In Europe, BULLS is a dealer brand so I think it’s some sort of partnership to lower prices maybe like Sams Club and Costco do in the US? I haven’t been given all of the information, just trying to get the bikes tested and covered. Overall, I liked both models (Bosch and Brose) but noticed that the Haibikes have some nicer battery integration on the downtube vs. BULLS which looks a little more basic… same with the BULLS Brose integrated battery which isn’t removable like Specialized and has more wires and bolts vs. being smooth. So you get a bit less aesthetic with BULLS but it also costs a bit less. The suspension felt fine but I’m really not an expert and didn’t get a back to back comparison.

Really like this design. Seems very efficient. Court, did they tell you what kind of maintenance the belts in the mid drive system will need, or how long they will last? Thanks!

2 years ago

Hi Joe! No, they didn’t talk about durability but I’m guessing it will be good because brands like Specialized are also using the Brose motor (and others in 2017) and these companies do a lot of research and demand high quality. I bet it’s similar to Bosch and you do get a warranty which is nice… Even if I ask “how reliable is it” I’m not sure what to expect or believe because the reps are often new with tech and aren’t forthcoming about weaknesses… it’s marketing

Hi Court- This bike is a work of art, however, they need to change the interface to more of an Intuvia type or similar. Looks like this company will do well in the US considering they have a direct competitor like Haibike, etc. I also like the stealthy look to the bike which makes it more incognito on the trails. I live in Chicago and I have been following most of your reviews (which are outstanding I might add). I am looking for a system with throttle like the E-Rad or HPC bikes. Any suggestions would be appreciated if possible. Thanks a million Court for all of your dedication and hard work. You are the BEST!

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

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.

This can certainly do light off road given the 120mm travel.

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

Have MT5/MT4 front/rear on my Bulls Monster E FS...one of the nicest break setups I've had. Really hauls those big meats down.

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?

Super down hill and mountain bike with a quiet Brose mid drive system with internal belts. An incredible 90 Nm of torque from this Brose motor! Not easy to remove the frame mounted battery for off the bike charging; however, the caliber of components on this bike overall are much better quality.

https://electricbikereview.com/bulls/e-stream-evo-fs-enduro-27-5/ The BULLS E-Stream EVO FS Enduro 27.5 is an enduro style full suspension electric mountain bike with longer 160 mm suspension travel, seat post dropper, 27.5" wheelset and premium hydraulic brakes. Downtube-integrated battery pack is out of sight and keeps weight low and centered across the frame but is not easily removable, it takes 30+ minutes to unscrew the frame, this means the bike stays heavier and the pack might get hot/cold vs. storing it separately. The mid-drive motor is made by Brose, it offers "trail tune" performance with higher 90 Nm torque output and is very compact and quiet, you start to hear it at higher RPM but otherwise it looks and sounds great. Available in two frame sizes (both offer the same high-step build and black with white and blue accent color scheme), I like the small transflective LCD control pad, it's easy to reach, simple to use and highly visible.

Hello thanks for the review, can you please point me in the direction for a review of the Zebra FS 2 27.5 or could you do a review of it ? Here is a link to the exact model, thanks products/bulls-e-stream-evo-2-fs

I wonder if they can integrate an "alternator/battery charger" that can recharge the battery once the juice runs out. Pedal Power Charging? So if you are riding cross country - you never need to stop to recharge the battery - just keep riding until it is charged again. THAT would make me buy one!

Really? Ride in place to recharge? Why not just ride? And it takes a long time to run out of juice...you might be done for the day by the time a recharge is desired.

Ridiculously expensive! Can't believe you're so lukewarm on affordable Sondors offerings who want to make ebikes accessible by pricing them reasonably. The industry will never take off if they persist in having such unjustifiably high price points. Instead of encouraging and disregarding the prices you should chastise these manufacturers for not doing better in this respect.

G Henrickson

Please stop. We need NO MORE posts on how this bike or that...is too expensive. It gets so old. Just go buy a cheaper bike.

According to the shadow at 9:33 the camera might be a Gopro with a gimbal handle or even a DJI Osmo. Gimbal keeps the footage really stable.

what top 3 bikes do you recommend for the $1000 price range? considering sondors with battery frame and suspension upgrade but i hear the specs are not as advertised. also wondering if the suspension and frame upgrade is worth it.

2 years ago

i think the support you can get from the community for free will be better than the support you pay from from a company. after looking in to this i think the best option for myself is to DIY. you can buy high quality parts and modify any regular bike of your choosing and end up with a better product for a fraction of the cost. right now i'm looking at a 1000w motor with 52v / 23ah battery and hydraulic brakes that will provide all the performance i need. if you haven't looked in to DIY take a look. putting something together yourself sounds just as fun as cruising at 30mph on a 1000w motor.

Simon Colby

I agree with you in that the looks/name don't matter. That said, a brand name brings with it better support when something goes wrong (learned that the hard way with my ebike), better r&d, higher quality electronics and components, and hopefully a really neat sticker for your helmet or something

2 years ago

i see your point. but consider what is the purpose of getting yourself an electric bike? to show off or to get yourself from point A to point B? if it gets you where you need to go and it provides the speed and range to fit your needs what does it matter what the brand name is? i learned this the hard way after wasting tons of money buying nothing but BMW.

Analogy: you can drop a hemi into a dodge neon, sure. However, at the end of the day it's still a neon

2 years ago

if you are still shopping around consider upgrading what you have to fit your needs. i hear about people buying sondors and doing dual motors, regenerative braking, twist throttle, upgraded controller, battery, etc. people are hitting performance numbers these stupid expensive bikes have for a fraction of the cost. people seem to get alot of enjoyment playing with it too.
