Summary

  • One of the cleanest looking full suspension cross country electric bikes I've reviewed, the battery and motor are built into the frame and match the matte black paint perfectly
  • Extra large battery capacity for longer rides, EnergyBus magnetic charging standard works on or off the bike and won't get bent or tip the bike over as easily if snagged
  • Uses the smallest plus sized tire standard 2.6" for precision and nimble handling but you still get improved traction and comfort, solid 180 mm hydraulic disc brakes
  • Compact transflective display stays out of the way and has a Micro-USB charging port built in, 20-speed drivetrain offers a wider range of cadence options, no dropper post

Written Review

Bulls offers an extensive line of electric mountain bikes and the E-Stream EVO FS 2 27.5 Plus is their cross country model with 120 mm air suspension from SR Suntour. Actually, to me this is something of a cross country / trail hybrid because I’m used to seeing 80 to 100 mm travel for pure cross country. The longer travel and larger Plus sized tires offer a bit more comfort but you lose some efficiency. Given that it’s an e-bike, that’s not a huge deal… and the battery capacity on offer is impressive. This is an efficient electric bike in part because it uses a high-end mid-drive motor but also because you get remote lockout for the fork and a clicker lockout for for the rear. The linkage driven single pivot suspension design keeps cost low because it’s not proprietary and it provides space for a water bottle cage or accessory to mount on top of the downtube. Bulls is one of the few electric bike makers to provide this sort of provision and I love it. There are even holes on the left chainstay for adding a kickstand if you wanted! At just over $4k, this is one of the more affordable name brand, premium motor and battery, full suspension electric bikes I have tested. Many competing offerings are in the $4.5+ or $5k+ range and they don’t look as good. It’s available in two frame sizes so you can dial in fit and the color matching extends to both suspension elements and the saddle. Some unique accessories include the locking ergonomic grips, compact transflective control panel (with Micro-USB charging port for phones etc.), and magnetic EnergyBus charging connector. I love that you can charge the battery on or off the bike but have some grips about how it fits onto the frame. Overall, it’s an easy ebike to appreciate, one that’s relatively quiet but plenty powerful.

Powering the Bulls E-Stream EVO FS 2 is a compact, smooth, geared center-motor. Brose makes this unit and I’m always impressed with how well it fits onto a bike frame, it nearly fades away! The black casing matches the matte black frame on the E-Stream Evo perfectly and the two-chainring setup almost completely conceals it from the right. This is one of the blurry areas of the bike to me because you’d think that more gears are better right? But on an electric bike, especially one that offers 90 Newton meters of peak torque output and three modes of power… one that responds as quickly as the Brose does, do you really need so many pedal cadence options? Yes, this is a cross country electric bike which means that it’s designed to be pedaled more and possibly go further than a downhill bike. The gears let you interact more directly with the bike and use human power to move those 55 lbs of weight. But perhaps it would weigh less and require less maintenance with a 1×11 setup? The Brose motor is smart and fast but it doesn’t offer shift detection. That’s up to you to as a rider, definitely ease off as you shift in order to let the motor ease back as well. I do appreciate the higher end Shimano Deore XT rear derailleur with Shadow Plus one-way clutch. This little grey clutch lever lets you tighten the chain to reduce bounce on bumpy terrain. But the bike also has a slap guard to help, and the front derailleur clears debris and acts as a chain guide. This motor is quiet when it is new but I have heard some other models that had a sandy sound, just a bit rougher, and perhaps that’s due to heavy riding at demo events? There’s a carbon / rubber belt inside, much like you’d find in a car engine like a timing belt, and it’s durable but also smoother than gear-on-gear designs like Bosch which produce more of a humming noise.

Powering the bike, an efficient little display panel, and the Micro-USB charging port built into the base of said panel is a 37 volt 17.5 amp hour battery pack that I would describe as “very large” in terms of capacity. Most other batteries, like the Bosch Powerpack 500 only offer ~500 watt hours but you get 647.5 watt hours here! That’s a lot of juice and it means you can ride further or climb longer… but also more weight. About 1.5 lbs additional weight in fact. Add to that, the second derailleur and chainring and you can see why the bike is slightly heavier than competing models. I should be fair here though, this is a more application specific ebike, I don’t know of many other cross country models, very few have more than 11 gears, so in many ways the weight is just fine or even pretty good. This battery contains long lasting Lithium-ion cells, it’s protected by a foam sticker along the bottom, and the downtube mostly hides it from the sides. I like how it looks but feel that taking it off is a bit more difficult and precarious. There isn’t a clear handle to grab and since you pull down vs. lifting up, it seems easier to drop. Unlocking the pack is a two-step process where you insert a key and then pull a spring latch before the pack sort of drops down and then you pull it the rest of the way. When you put it back on the bike, you can click it in without locking it with the key. I feel like Bulls should have a spring lock so you always have to use the key to get it off the bike. It would be a bummer to forget to lock it and have someone steal the pack or accidentally bump the lever and drop the pack out the bottom. I also feel that the locking core is positioned dangerously close to the left crank arm and that the little rubber flap which covers the charging port (when the battery is mounted to the frame) does not seat easily or as tightly as most competing products. Who wants water, dust, or mud to get in there? I would probably leave the battery in the bike most of the time and just store the entire thing inside for safe keeping. The magnetic charging cord would be connected regularly and I love how easy it is to connect vs. pushing in or trying to line up, and if it gets tripped over there’s a lot less that can go wrong.

Operating the bike is very straightforward. You don’t have to press the power button on the battery to get it started like you used to. Now, that power button is more of an LED power indicator readout. To get the main display switched on, just press the little button along the top of the button pad (located near the left grip) and it bursts to life. Your current speed, battery charge level, and assist level are shown… and that’s it. You don’t get the additional stats like trip distance, average speed, max speed, or range estimate, but it also takes up less space. The display uses a transflective readout that looks great in harsh sunlight and even though it’s a bit further to reach with your left thumb, it’s intuitive to use. Just click up or down to increase or decrease power. You can feel it click, thank goodness, because the assist level indicator graphic is tiny. Four boxes communicate off, level 1, 2, or 3. I tested walk mode for the video review and noted that it works well but depends on the gear you choose to alter the walk speed. If you’re in a low gear, as I was, then walk mode is going to be very slow. The display panel is a great compromise in a world with lots of bulky, overdone, glaring screens… but it is not removable. I’ve already mentioned the Micro-USB charging port but it’s an awesome feature worth describing a bit more. A rubber cover (that seats well) keeps it clean and the port is situated just below the main button pad, if you plugged a smartphone or Garmin GPS device in, you could tap into that massive battery for longer use. Even a headlight or something fun like external speakers would work. I dislike wearing headphones while cycling because it’s dangerous to your surroundings (not hearing animals, cars, or other riders) and the sound of wind really disrupt the tunes. I don’t want to wreck the peace and tranquility for other riders but an electronic bell / speaker product like this could be a good way to get some tunes going safely when you’re riding alone.

I had a blast riding this bike on some access road terrain in Southern California and can easily overlook some of the inconveniences around the battery for how great it looks. Weight is well distributed and even though the Tektro brakes strike me as mid-level, the drivetrain is great. I’m used to seeing round flat grips vs. ergonomic but these were locking and rather thin so I think they would work well and provide a comfort boost on longer cross country rides. It’s neat to see an application specific electric bike here and the 27.5″ x 2.6″ tires performed great. They offered precision and quickness with a dash of comfort and traction. Thru-axles with quick release mean easy trail maintenance and transport. The solid 2+ year warranty, two frame size options, and extensive dealer network makes it easy to find, buy, and enjoy. Big thanks to Bulls for partnering with me on this review, meeting me on the trails, and allowing for some back to back rides. I got to compare different models and get a sense for how one geometry and hardware setup was different than the next. Please note that the suspension was not sagged for me and rode a little stiffer than it should have (especially the rear). This is the kind of setup that a shop could help you get right but I often have limited time and they set bikes up for heavier riders at demo events (I weigh 135 lbs).

Pros:

  • The bike looks amazing, both the motor and battery are well hidden in the frame and blend perfectly with the matte black paint
  • You can ride cross country or trail with this bike, the 120 mm travel is versatile and highly adjustable here, both shocks are air so they keep weight down and can be sagged to fit your body weight more precisely
  • This is one of the very few mid-drive electric bikes with a high-end motor and more than 11 gears, you get a front and rear derailleur with a total of 20 gear combinations, this fits the cross country climbing and trail scenarios well
  • Sturdy thru-axles on the front and rear wheels improve stiffness and support longer Boost hubs, the 2.6″ tires are at the low end of Plus size (2.6″, 2.8″, and 3.0″) so you save weight and get precision along with some float and bump deflection, another great choice for cross country and trail
  • Available through a wide network of dealers so you can get help setting it up and keeping it running right, Bulls offers a solid 2 year comprehensive 5 year frame warranty on their products
  • Two frame sizes allow you to find a proper fit and the $4.1k price point is pretty good for a full suspension model with mainstream drivetrain in my opinion
  • The Brose motor is exceedingly quiet and smooth, it uses a Carbon belt drive to transition power internally and that dampens vibration
  • Quick wheels and seat tube as well as a removable battery let you reduce weight and size for transport, I always take the battery off when hanging bikes on car racks and usually take at least one wheel off when putting it in the back of a station wagon
  • I appreciate the color-matched suspension fork, rear shock, and saddle, I also like that you can mount a bottle cage on the downtube where the plastic battery casing extends up
  • The Shimano Deore XT derailleur is pretty high up on the Shimano groupset offering and I like that it comes with Shadow Plus clutch here so you can tighten the chain for bumpy terrain (just push the grey lever up and towards the back of the bike to enable it)
  • Powerful 180 mm Tektro hydraulic disc brakes perform well and keep weight down with a dual-piston setup on each caliper, the ergonomic grips lock in place and felt good, I also appreciate the threaded wire connectors (for strength and keeping water out)
  • I like that the suspension fork has a remote lockout, there are provisions for mounting a kickstand on the left chainstay, you can turn the bike on directly from the button pad now vs. pressing the battery first, and the battery charging port cover fit a bit better than some of the other Bulls e-bikes I’ve tested
  • The small transflective display panel stays out of the way and reduces clutter on the handle bars (especially important when you have two sets of shifters for the two derailleurs) and it even has a Micro-USB charging port built in to fill your phone or other portable electronic device
  • Walk mode actually works on this electric bike, which is great considering that it’s ~55 lbs, just make sure you’re in one of the three levels of assist first and then hold the walk button, changing gears will make the bike walk faster or slower
  • The Brose motor is incredibly quiet and responsive, it uses standard sized chainrings and just works well… at least the brand new ones do, I have heard some demo models with louder motors that might have been pushed harder? I owned one for over a year myself however and it stayed quiet

Cons:

  • The suspension design appears to be Linkage Driven Single Pivot which is an open design (costing less than a licensed proprietary design) which does produce some braking feedback and isn’t as efficient for pedaling… although that’s less of an issue on an ebike, the rear shock does have lockout so that helps a lot, you may still experience some kickback when pedaling over fast bumps
  • The bike’s a little heavy at ~55 lbs but that’s partially due to the high-capacity battery pack which weighs 7 lbs vs. 5.5 lbs on competing standard battery models and the Boost setup with larger tires
  • Offering 90 Newton meters of torque, the Brose mid-drive is incredibly powerful for climbing but it doesn’t offer shift detection like Bosch, considering the dual-derailleur setup here, that could put more strain on the drivetrain and require more maintenance… at least it measures pedal torque so you can back off a bit as you shift to keep it smooth
  • The locking core for the battery is very near the left crank arm, along with the charging port… it’s all a bit crowded and I wish the charging port cover seated more securely, at least the charging plug is magnetic so it can get popped out without causing damage if someone trips over the cord
  • I love how the battery looks and appreciate the foam sticker underneath to prevent chips and scrapes but struggled to get the pack on and off since it seats up into the frame vs. down from the top, it’s not something you want to drop and it doesn’t have any handles or good gripping points like some other packs
  • I’m getting pretty used to dropper seat posts on full suspension e-bikes but I guess in the cross country world, you don’t need it as much? Still, with 120 mm travel vs. 80 to 100 I could see trail riding with this and think a dropper could be worth having, consider the 30.9 mm Magura Vyron wireless dropper post for easy install and swapping between ebikes
  • I like how simple the display is and feel that it shows the most important menus such as speed, battery capacity, and assist level… but it doesn’t show range, odometer, trip distance, clock, or any other useful stats like the larger displays do

Hey! Looking to buy a bike to commute to work/trail fun and was wondering if this would be a good option or should I just stick with the Haibike urban plus 2017 I dont see the review for that bike on here just yet to I am hesitant on buying that one. This bike does look like a great bike and I like the design of it. Just want to make sure it would be a good option for commuting to work 20 miles roundtrip every day. Thanks for your hard work!

Hi Bob! Sorry for the delayed reply here. Have you already chosen an e-bike? I love the full suspension setup of this and other bikes because it offers great comfort and allows for some trail and mountain riding between commuting. Adding a rack for transporting gear to and from work won’t be as easy since it’s not a hardtail but wearing a backpack would work fine. Haibike makes awesome electric bikes but the Urban Plus is way different from the Bulls E-Stream EVO, it has no suspension so it will be more efficient but probably less comfortable. Both of these electric bikes should have no problem with your 20 mile round trip commute and both have removable batteries so you could charge half way if necessary (though I think you’d be fine doing the whole trip on a single charge).

I recently purchase this bike and I confirm it is an absolute pleasure to ride. The folks from Bulls helped me answer a number of technical questions and their USA team was incredibly responsive. I wanted a full suspension e-bike with a large concealed battery, and a relatively comfortable geometry. The Brose motor is smooth, silent and powerful uphill. Although I am petite I got a medium size and replaced the stem with a shorter one. I test rode several e-bikes and this stood out as the best fit for me. Highly recommended.

Awesome! First of all, I love your name Flavia :D and yeah, so glad to hear you got excellent support from Bulls. That has been my experience too, their team is responsive and very positive to help. Good for you, being able to test ride a few models, I love how quiet the Brose motor is and agree that this is a stealthy looking ebike. Thanks again for chiming in here, have a blast out there!

I recently purchased this e-bike and I am having a blast with it. It is a great all rounder. Comfortable for the relatively flat beach trails and enough suspension for medium difficulty trails. This video review was very helpful in helping me make a decision. The bike is so beautiful that it gets heads to turn. When I took it to the shop to have the dropper post installed many were asking about it. I tried a few e-bikes and I enjoyed the smooth support of the Brose motor. I do have range anxiety so the large battery was a win for me. What made me choose this bike is the geometry: it has a short reach and tall stack even in the medium size. It also has a 70mm stem which can be replaced with a shorter or longer one according to how you like to ride. Overall it was a great fit for me. I was able to add a water bottle holder and a kickstand that I can eventually remove when going to more challenging trails. I love that I can keep my phone charged from the battery since it drains while I am using it to navigate and discover new trails. Bulls is ahead of the game with concealed batteries both with Brose and Bosch motors. If you have more hilly trails then check out the 2018 Bulls Six50 Evo AM3 that is also reviewed on EBR reviews since the Bosch motor is more powerful uphill. The battery is smaller though on the AM3 and the Bosch did not have the same natural feel than the Brose for me. My trails are 70% flat or moderately hilly. The E-Stream EVO FS 2 27.5 Plus has a dual drive train with gearing that will help uphill on a steep climb. The local Bulls shops have been super nice and generous with advice and offering their best prices. I recommend all of them: Myron ebikes in Fullerton, eVeloPros in Santa Ana, LaFlyRides in Hollywood, Bikezz in Santa Monica and OpenTrails EMTB in Altadena. I paid to rent out a few e-bikes before purchase to figure out what worked best for me. I learned something about fit or motor from each of the shops listed. I talked also to a few people at Bulls USA before making a purchase and they have been very responsive and helpful. Bulls is a great ebike company and they have excellent customer support.

My Bulls FS3 eMTB has a Brose motor, same as your Turbo Levo, Jim. Sure, Specialized "custom-programmed" the motor's software, but it's still cranking the same 90Nm of extra torque through the drivetrain. I also own a Haibike Sduro Allmtn+ with a Yamaha (80Nm), and a Motobecane w/Shimano (75Nm). My friends and I have put hundreds of trail miles on all three, and we've broken a few chains.

We've all been mountain biking since the early '90s, and consider ourselves to be experienced riders who know how and when to shift. eMTBs, however, are a different story. I find that they're far more susceptible than unassisted MTBs to bending chain links when shifting under any kind of load and/or the slightest cross-chaining, and are totally intolerant of standstill shifts (especially when caked in dried mud, which makes everything stickier). Of these three ebikes, the Bulls w/Brose has been the most prone to chain breaks, even when freshly cleaned and properly lubed. I suspect it's because of the motor's higher torque (it's also the heaviest of the three).

My 2002 Stumpjumper could go indefinitely without lubing its chain, and did 15 years ago when I first got it. One of my buds now wants to buy his own eMTB, which is great, but he only cleans his current MTB semi-annually, and maintenance is not something he does frequently, either. I told him what I'm saying to you - if you expect to treat an eMTB just like a mountain bike, you'll likely be disappointed. For me, pedal assist amplifies the fun factor by at least 10, but also requires three times the maintenance.

That's a trade-off I'm willing to make.

Hi Scott,

It's converting the front crank, either a 2 or 3 chain ring to a single ring. You can check out my post in the Bulls forum here:

https://electricbikereview.com/forum/threads/my-unintentional-1x11-conversion.15912/

You only need post adapters to increase the rotor size. I'll take some photos and post them back here.

Nice photos.

Curious what "converting to a 1X" means?

What all is involved in increasing the rotor diameter- is it necessary to custom weld the caliper mounts into a new position?

Riding an ebike at night is fantastic.

HI All,

Just roaming around the site and found this thread. I've posted in other threads but never really took the opportunity to introduce myself. My name is Dan and I reside in a suburb of SLC, UT. I currently own two bikes. The first is a 2015 Cannondale Trigger 4. It's my "analog" bike and the one I ride in areas where I can't legally ride my eBike, like Ski resort riding, MTB only trails in Moab, forest and BLM land.

My regular ride is a 2016 Bulls EVO E-Stream FS3 and it has been fantastic. Especially since converting it to a 1X, installing a dropper post and increasing the rotors to 203mm. It has allowed me to ride longer, to keep riding with my 23-yr old son and to ride without knee pain.

I recently bought a couple of Bontrager ION 800 R LED lights and have been night riding. Terrifyingly awesome!

@Boca, sorry to hear you are going through these issues. Normally things are really easy where it would take a few days to diagnose the issue and fix it.

I'm very surprised that the box wasn't opened, batteries inspected and charged up fully prior to giving them (one) to you. This is what happens I guess when steps get missed.

But happy that the new battery is up and running and the 2nd one is on it's way to you.

As mentioned above, our expereince with Bulls has very positive and customers love their bikes.

safe riding & best regards,

Hey guys, thanks for the new interest in my issue.

My bikes have been in a shop near Miami at the request of Bulls for evaluation. Communication with the shop has been difficult due to a language barrier, but they are sincere. Communications with Bulls has been on and off, but also sincere. The tech guy at Bulls in California is probably covering the whole country and has limited time to communicate, but here's the deal:

Bulls wanted the batteries hooked up and tested according to their protocol. The shop did that but one came back "incomplete and timed out." Bulls had a hard time getting the shop to finish that one, but Bulls finally decided to replace both batteries. The shop earlier said they tested fine, but they, like me, were unable to charge them with my chargers or theirs. Nobody is telling me what the problem is, but I finally pried some info out of the shop. They said there was a manufacturer lot of bad batteries wherein a case screw was grounding out one of the cells. So, my theory had been that my chargers were tripping out. I could hear them click when hooked up to the battery. So, I guess the batteries were shorted. The mystery is why two batteries would short out at the same time. I had had problems with one of the batteries from day one. It would never charge over 80 %, but both were chargeable until I ran them down to 20% and 40%.

The shop told me the new batteries had come in. It is an hour's drive for me. I got there and the box contained only one battery. The shop felt bad about it and said they would have the second battery delivered to me when it comes in. When I got home I charged the battery. It went to full charge and the charger acted normal. Looks like the chargers are OK - just a bad battery. Now if I can get the second battery I'll be good to go. UPS says the battery has been at their facility In Jacksonville since Feb 4 with no updates. Geez...what's going on?

Scooteretti
1 week ago

@Boca indeed would love to hear to outcome. Sounds like a BMS issue within the battery. Multiple known chargers that are know to work that don't work when put on a battery would indicate a poor internal connection or a bad BMS. My guess is BMS.

Keep us posted on the outcome.

I am a big fan of the Bulls bikes and they are reliable. Liek anything nothing is 100% perfect but you at least have a brand that offers great support and a strong customer service attitude. They will get you back up an running.

Will

Jeffb,
My Levo is an aluminum hard tail so the handling of a full suspension Levo I can't really speak to. The Brose motor is great and is very quiet. This new Shimano e8000 motor is just about as quiet and I hardly notice its on. Both motors are really smooth and responsive. The Shimano motor is smaller and lighter and the Focus has a smaller battery in the down tube which is done on purpose to keep the bike lighter. Its in the neighborhood of 5 pounds lighter than the Levo and that weight is noticeable to me. Right now I'm loving the new firmware update that has the trail mode constantly sense torque from your pedaling and apply more power when you provide more power. Very cool.

Hi J I am currently looking at both the carbon Levo expert and Jam2 C plus pro and the fact that you have both was wondering which one do you like the best. I currently ride a Bulls e stream evo 45 fs and I really like the brose motor mainly for how quiet and smooth it is the main problem with the bulls is it weighs 56lbs. What is your impression of the brose vs the shimano e8000. Keep us posted as you ride the Jam2.

I bought a Bulls Green Mover E45 this year. Very good and decent bike with 1 mayor flaw: It only supports to 45 km/h - 28 mph in the highest support setting.

Sport: 45 km/h - 28 mph
Climb: 35 km/h - 20 mph
Tour: 35 km/h - 20 mph
Eco: 35 km/h - 20 mph

This bike contains the same hardware as the Bulls Outlaw. (Battery from BMZ, Engine from SR Suntour etc....)
I have been in contact with the following parties:

- My local bike shop says that Bulls does not provide any software updates
- Manufacturer (ZEG / Bulls) says that an update is not needed
- SR Suntour says that applying an update is possibly with a writing device that you plug on the controller and that it is really easy.

In this thread i noticed that the issue was resolved by applying a software update on a Bulls Outlaw:
https://electricbikereview.com/forum/threads/bulls-outlaw-e45-green-mover.4997/

I am looking and looking but can not find any way to update the software on my bike. It is really frustrating since the bike consumes a HUGE amount of battery in the highest Sport mode. But if i go down a level it only supports to 20Mph which is too slow.

What is even more frustrating is that the Hercules Alassio E45 supports all times to 32 mph. This is the sister model of my Bulls Green Mover and nearly the same.

Hope that somebody has the answer or can give some explanation for my dealer how this can be done. The bike would be perfect if this flaw could be removed.

Thanks and kind regards from the Netherlands.

Thanks for the info. I really want a Riiese &Muller (R&M) ebike with the Nuvinci hub & the carbon belt(Charger or Delite)! Why? I already own a Trek Single Speed with a carbon belt. The lack of constant maintenance required when compared to a chain and derailleur has been a godsend. However I am concerned because the ability to cruise comfortably between 25-28mph seems to be limited. I am a power rider who prefers spin at a moderate 60-80rpm in a higher/harder gear. The bike I buy, if it is a R&M, will have two batteries. I also don't plan to use it for commuting either. What I want most is a recreational, fun, fast, ride that will easily provide the opportunity to go off the designated bike path or road. With two batteries I plan to not be limited by distance and/or concern about the mode I'm in - be it Sport or Turbo! Even, if I buy the Bulls EVO TR Street, I plan purchase an extra battery.
The final factor will be test rides of both bikes. Hopefully the Nuvinci will have a larger gear range. Listening to Court very closely has caused me to infer that 28mph Speed Pedelcs from Bosch probably should have the 22 teeth front sprocket to counteract the decrease in torque, 75-60.
PS: There is a local Trek dealer within five minutes of my home that I trust to provide any services necessary. The shop sells Trek. Bosch, ebikes also, so I am not worried

Unfortunately I can't provide much advice because I have no experience with Bulls nor do I have experience with full suspension bikes. It could be a superb bike easily competitive with the R&M in which case I would say you might want to stay with the almost local Bulls dealer.

I do own the R&M Charger with the Nuvinci (28 mph bike). In the Detroit area, when I started shopping there was very little in the way of e-bike inventory available for test riding (still pretty much the case). After trying a bunch of bikes at an e-bike expo in Wash D.C. (not including Bulls or R&M) I opted to order the R&M as I knew the Bosch system and style of bike would meet my needs. I trusted in the R&M reputation. I ordered from Propel in Brooklyn but when it arrived from Germany I flew to Brooklyn to try it out (ensure the sizing and that I liked the bike). For me, ordering from a distant dealer (Propel) has worked out well for two reasons: 1). Propel is a good/honest outfit and is customer service focused - so everything with the sale and shipping was as-promised and they have been responsive to my follow-up questions; 2). I have an LBS that is mostly a Trek shop but which is Bosch certified - they are really receptive to servicing bikes that were not purchased from them and in fact they carry a large banner on the front of their store that says "we service all makes and models". So while sometimes it is a lottery there as to whether you'll get a tech with little or much experience, I know I have service available and they can figure out most issues. I suppose if I had a warranty issue with the R&M (and not the Bosch system) I might have to go through Propel but I am confident they would be helpful. Since I am a very bad bike mechanic, having an LBS nearby that is happy to service bikes they didn't sell took a lot of the risk out of my transaction.

In your case: Have you talked to the Bulls dealer and did they say they might get some demo bikes in soon? Again I think the bike will be available soon because Court showed it in his recent Urban Evo video. And I'd expect Court's review on the TR Street to hit this website any day now. So maybe the Bulls would be the way to go because you have a dealer fairly close. Of course the ideal is that you can try both bikes but I understand that will require some waiting and some logistical and perhaps expense issues. If you decide to have a bike shipped to you and if you aren't a great mechanic then I'd try to be sure that you have an LBS available that can provide basic bike service (wheel truing, brake bleeding etc). And for Bosch service, you'll have to go through a Bosch dealer regardless of where you buy. I would imagine that in the Chicago area it shouldn't be a problem to find a Bosch servicer. Some folks on this forum have said that some dealers will charge for firmware updates and such. I haven't had to perform service on the Bosch system yet so I can't speak to this.

As for the Nuvinci, I've expressed my opinion in my thread about the Charger. It isn't a bad system and it is working for me but when/if I replace my R&M, I won't select the Nuvinci system. I have mostly flat terrain for my commute and the Nuvinci doesn't quite have the gear range to allow me to cruise under that 28 mph cut-off comfortably. I can cruise maybe at about 23 mph but at that speed I'm spinning pretty fast. I have hit 26-28 mph in short bursts but I'm really spinning and working hard. I have only once surpassed 28 mph on a flat and that was with good pavement and a strong tailwind. I can't help but having the feeling, when I am at the end of the gear range and cruising on a flat, that I am just lacking one more gear. For most of my commute, the top speed isn't so relevant because I have a lot of start/stop city riding. But for the couple of stretches I have where I can do some cruising, I would really like an "extra gear". The system has been reliable so far and as I've learned to use the Bosch assist levels like gears (mostly Eco to Tour sometimes to Sport) then I find I don't have to worry about changing gears that much. This contrasts to my Haibike with derailleur where I'm shifting all the time.

can you please elaborate on your statement? I have never seen a Honda or Yamaha off road motorcycle with pedals and a crank.... Class 1 ebikes are designed for less abled riders or for those who want to ride longer or need help on steep climbs. To me it's like having a more powerful front derailleur with extra gears. Ebikes do not pollute and do not have a throttle. Are some bikers with this negative attitude towards ebikes just jealous or perhaps wanting to protect their strava accomplishments? Public trails are open to everyone -- they are NOT ground for competition on timing and fitness by macho riders on strava .... If you want to compete please keep off public trails and join the Olympic team. I just want to enjoy trails longer and need help on climbs. What entitles you or others to make these kind of statements?

Flavia Sparacino congratulations on your choice. I have ridden a brose powered Evo. I test rode the Bulls Evo E-stream 2 FS (Zebra edition). In comparison to the haibike. The bulls had a 27.5+ tyres and the Haibike 29 because I use the bike for long distance travels 29ers are better because basic physics, larger wheels carry more momentum so they roll smoother. And require less energy to keep moving when already in motion. Aside from that for me personally I don't notice the difference in motor torque. Bulls has 90, Yamaha 80 but in a real world. Don't notice it. I will admit. When you first use the Yamaha it isn't as nice, because of the way the motor algorithm works. Torque goes down above 100 Rpm. But I've come to understand if you're doing 100RPM you need to shift the Yamaha system isn't about spinning. But about power. And because the bike is limited to 15.5 Mph. Going above that reduces the power and it's pretty much like riding in Eco. Thank you for the advice. Good luck with your bike. Enjoy the bike. Zane.

I was going to do the same and then I had a chance to test ride the Bulls and the Haibike fullnine back to back at an ebike store. I ended up liking the Bulls a lot more. It feels more planted (60mm bottom bracket) and it rolls great. I was concerned it would be too big for me in a Medium but it is not: I installed a shorter stem and I will shorten the handlebar width a little. Dropper helps too.

No, I like the geometry of the Stumpjumper and Levo (designed around the same frame) for a bit more all mountain riding vs. cross country. The Bulls display is easier to work with and I love the Micro-USB but I don't need 20 speeds so the cross country setup here just doesn't suit my ride style. Also, the Levo was out a lot earlier so I wouldn't have had the choice. I do appreciate the $2,500 I would have saved getting this vs. the Levo Expert though. Specialized gave me a dealer cost discount because I reviewed it but I still spent what seems like a fortune.

I really like to watch the reviews but lately I have been skipping them at the first mention of the prices. These are breaking into used car territory. A BIKE over $1500 is a very serious purchase for many people. I realize these are very high end, well featured and equipped bikes, but there are those of use that will never be able to get one of these. Your reviews are very comprehensive and thorough and that is very appreciated. Would it be possible to feature some lower end bikes as well, as you pass through the market place? I know they won't be as much fun to test and put through their paces but there has to be more economically priced bikes out there. Thanks as always.

It's not really that hard to find some value e-bikes... you can buy plenty of them from http://www.aliexpress.com or (alibaba.com). You can even just pay $200 for a conversion kit.

I know you may say made in China, but many of these high-end bikes are made in China as well. Shenzen is a higher-end manufacturing center in China (like their silicon valley).

Worth looking at products from there... also I read those with a high number of positive customer reviews:
