Written Review

The variety and price range of electric bikes has grown significantly since I entered the space in 2012. BULLS is contributing to this diversity of products by offering the Aminga TR 1 in the United States starting in 2018! This is a women’s specific electric mountain bike, designed specifically for cross country and trail riding. It provides plus air suspension that can be sagged (pressure adjusted) for a range of body weights, is featured in two sizes (small and medium), and comes with a shorter stem because ladies tend to have shorter arms than men. Of course, the most obvious nod to the finer sex is the color scheme with teal or turquoise and fuchsia paint. But don’t underestimate this ebike, because it’s very capable and built around some of the latest design fundamentals such as stiff thru-axles, wider “Boost” hubs that offer a sturdy spoke bracing angle, and extra wide plus sized” tires that increase traction, float and comfort. It’s running one of the most widely recognized, highest quality drive systems from Bosch, and it comes with a two year comprehensive warranty and nation-wide dealer support. Of course, all of this contributes to a higher price tag and the $4,299 MSRP is on par with the other bikes from BULLS that seem to be colored and designed more for unisex or male riders. The price might actually be a little on the high side for the Aminga because the volume sold could be lower. I’m just guessing here… check out all of the other BULLS models and my reviews to decide for yourself. The Shimano Deore derailleur is good, but a step below SLX or XT, and the SR Suntour suspension offers open or locked vs. a medium setting as some of the RockShox and Fox models provide.

Driving the bike is a high-powered centerdrive motor from Bosch called the Performance Line CX. It’s a mountain bike specific model with a higher torque rating of 75 Newton meters, a sportier quicker feel, and a special drive mode called eMTB that offers low to high output based purely on pedal power vs. making you click up and down with a control pad. The major trade-offs are that it can burn through battery capacity a bit quicker and produce more noise. A lot of this depends on which level of assist you choose to ride in, and I noticed that Paula (the young female rider in the video review above) was struggling a bit with the higher levels of assist. It was causing her to surge forward a bit and then cutting out because her pedaling wasn’t super consistent and we were on flatter terrain. If you stick to the lower Eco and Tour settings, this motor can deliver outstanding range and feel very smooth, but eMTB mode is also smooth and quiet if you aren’t pedaling hard. The motor is empowered by how you pedal and measures the rear wheel speed, pedal cadence, and pedal torque over 1,000 times per second. It even senses when you’re shifting gears in order to ease back and reduce drivetrain wear. Imagine your leg forces plus a motor that’s rated 250 watts to 500+ watts combined to pull on a chain, through the rear sprockets, and on that derailleur. The Bosch motors are unique in offering this shift detection, and it’s software driven and imperfect in my experience but much better than nothing. For best results, I still ease back on my own pedaling force when shifting gears. The motor can operate at up to 120 RPM (pedal strokes per minute) which is higher than some other mid-drives and this means you can spin faster with support vs. having to shift down to maintain support. It’s great for someone like me with a sensitive knee and road cycling background :)

Powering the Aminga is a Bosch Powerpack 500 which is the premium pack right now, offering 25% more capacity than the older Powerpack 400 with only ~0.5 lb increase in weight. In fact, the battery pack looks the same as the older Powerpack and uses the same mounting interface, so it’s backward compatible. What I really love about this pack is how easy it is to charge, using the included fast 4-Amp battery charger. You can charge it on or off the bike, and I usually remove it to reduce overall weight for lifting, wheel service, and transport. The pack locks securely to the frame but let’s say you’re commuting to work with this bike during the week… you can take the pack off and bring it into the office for a refill before going home. And, if you want to really protect the pack, I suggest storing it in a cool, dry location because extreme heat and cold can degrade Lithium-ion cells. Note the white stickers that have been placed along the battery pack and parts of the motor to help them blend in. I love how BULLS has styled their downtube to bring the battery down while angling the motor to raise ground clearance and help it blend into the frame. This is a beautiful looking e-bike and all of the electrical system weight is positioned low and center, right where you’d want it for optimal handling. There’s enough room for a 120 mm suspension fork and rear suspension, but there wasn’t space for bottle cage bosses or for the seat post to slide down super far. I actually cut the end of the seat post off so the saddle could go lower for Paula. It’s not a huge deal to do, just get a hacksaw and then sand the end when you’ve cut part of it off… be sure to leave enough post so that you can stick some in for a sturdy hold with the seat post collar. As someone who mountain bikes a lot, I have become a fan of seat post droppers (which let you raise and lower saddle height with the press of a button) and Race Face sells a 30.9 mm option that could be installed on this bike. Note that the front shock can be locked out directly from a switch at the handlebar and the rear has two settings for open or closed that are activated by a little blue lever you can reach while riding. The rear suspension is actually pretty nice, with a two-pivot action which keeps the wheel vertical vs. rotational and helps to keep the chain length constant and improve braking consistency.

Operating this electric bike is pretty easy once you’ve charged and mounted the battery pack. Just press the little black power button at the top edge of the Bosch Purion display panel. This display is nice because of how compact and simple it is but you do sacrifice some functionality, removability, and accessory charging options that the larger Bosch Intuvia display offers. For mountain biking models, BULLS has moved almost completely to the Purion and I think it’s partially a cost savings thing. The display is still relatively easy to reach, glows faintly in the dark, and has incorporated walk mode (which some other brands like Trek have disabled). You can activate walk mode by pressing the black button on the bottom of the display and then holding the plus button. It’s a neat feature for climbing steep hills (when you might not feel comfortable trying to ride up or maybe you tried and had to step off to avoid tipping). There are two more buttons on the display, plus and minus, that let you cycle through the four levels of assist, or you can pedal with the motor completely off and use the display to show your speed and activate lights. The Aminga TR 1 is compatible with MonkeyLink front and rear lights and fender options. There are special interfaces on the stem and seat post clamp which are pre-wired to work with these branded accessories… and I love that! But the headlight system isn’t adjustable in terms of angle, so you can’t shine it up or down depending on how you like to ride or where you are at. Anyway, to turn on lights, just hold the plus button on the display for a few seconds and an icon will appear. The minus button has a couple of extra features too, if you hold it down, the display cycles from assist level to trip meter, odometer, and range estimate. I love range estimate because it’s much more interactive and precise than the simple five-bar battery infographic at the top of the display. With range estimate, you can click + or – and cycle through assist with realtime readouts of how far the bike thinks it can go before the battery will completely run out. This range estimator uses your last mile of activity, the battery charge level, and the level of assist in use to dynamically update in realtime. The final secret feature in the display is that if you hold minus and then tap the power button, you can change units from miles to kilometers and back. This was a big hit with the family shown in the video because they are from Spain and were more used to Metric than Imperial.

All things considered, the Aminga is a trail worthy electric mountain bike with a few minor tweaks to make it comfortable and attractive to women. The shorter stem, ergonomic grips, ladies saddle, and color choices all contribute to make it unique but the drivetrain and motor are exactly the same as many of the gender neutral or male models designed for similar use. I had a blast testing it out and Paula eventually got the hang of the dynamic drive options and sensitive torque response in higher levels of assist. We didn’t really do this ebike justice and it’s way more capable than an around town type of bike, I’m not sure Paula could really appreciate the quality full suspension components, plus sized tires, and Boost with thru-axles because the terrain we tested on was so tame… but it still performed well. The bike does have provisions for a rear kickstand but no rack or bottle cage options so I’d suggest getting a hydration pack. The cockpit is clean and in eMTB mode you only need to think about what gear to shift into and how hard to pedal vs. what level the motor should operate at. Again, it’s neat that you can lower the tire pressure (or run tubeless for the lowest pressure options and reduced weight) and sag the suspension to fit your body weight. I’d like to say a big thanks to Paula, her sister Carla, and father Victor for helping out with this review and to BULLS for partnering with me on this post. I got to review many of their models back to back this year which provided more insights and details, which hopefully makes it a richer experience for you. Comments and feedback are always welcome below and in the forums!

Pros:

  • One of the few women’s specific electric mountain bikes I have seen in the USA, and this one offers high quality components and a top-of-the-line drive system from Bosch
  • The Bosch Performance Line CX motor is one of the most responsive, high-torque, and reliable motors on the market right now, it’s perfect for cross country and mountain biking because it can produce up to 75 Newton meters of torque vs. 50 Nm or 63 Nm on the standard Performance Line motor
  • To make their drive system less distracting for trail use, Bosch offers eMTB mode for the CX motor, you get there by arrowing up (between Tour and Turbo) and it offers a full range of power without clicking any buttons, it’s more of a torque sensor response and it works surprisingly well when pedaling gently or hard… it responds
  • The Shimano Deore 10-speed drivetrain offers good range for cross country and trail style mountain riding and I love that it comes with the Shadow Plus clutch for snappier shifting and reduced chain slap
  • With all of the Bosch motors, there’s a shift detection software system built in that can sense that gears are being changed and it tries to ease off of the power to reduce strain on the drivetrain, it’s not perfect but it’s better than nothing, the only other drive systems I know of which do this are some Impulse motors and some customized Bafang systems which are usually installed as kits
  • Battery and motor weight are kept low and center on the frame which improves stability and handling, it also reduces unsprung weight compared to a hub motor since this is a full suspension ebike
  • The Aminga TR 1 comes with wider “Boost” hubs that improve wheel stiffness and strength by widening the spoke bracing angle and the 2.6″ wide tires are considered “Plus Sized” which offer more air volume for comfort and larger contact patch for control
  • Thru-axles on the front and rear wheel provide strength and the front skewer is setup with quick release which makes the bike easier to service or break-down for transport/lifting
  • The battery pack can be charged on or off the bike (for convenience, battery protection, and reduced weight for transport), I recommend storing packs in a cool dry location to keep the cells healthy
  • The locking core used for the battery pack is made by ABUS and comes with a card that has a code written down for you to use when ordering other locks (chains, u-locks, folding locks) so you don’t have to carry multiple different keys
  • Not every electric bicycle company has mastered the design aesthetic of integrating the Bosch motor as well as Bulls in my opinion, look at how it’s angled up and incorporated into the seat tube and downtube to raise ground clearance and just not stand out as much
  • I’ve become a fan of the MonkeyLink magnetic clips for adding a headlight and rear light or fender, it’s cool that this bike comes with some of those parts, even if you don’t use them

Cons:

  • This is the only BULLS electric bike being brought to the US for 2018 and it strikes a balance between affordability and higher-end specs, some people felt that the Deore derailleur should have been SLX or XT but at least it has Shadow Plus clutch, I think it’s pretty good but you could always choose one of the “guys” bikes even though they look more masculine in terms of colors and designs
  • I’m not a huge fan of the Bosch Purion display panel because it cannot be removed, you can’t angle it without tools (to reduce glare while riding), it doesn’t have a smartphone app, you cannot charge accessories with the Micro-USB port on the side (that’s just for diagnostics), and it doesn’t offer as many readouts as the Bosch Intuvia (such as shift recommendation, timer, clock, max speed, average speed), but some shops will help you upgrade if you’re willing to pay ~$150
  • One relatively minor trade-off that Bosch has made with their Performance Line motors is to incorporate a reduction gear so when you turn the crank one time the chainring actually goes around 2.5 times, and this does create some mechanical friction, the upside is improved response, improved efficiency, and improved chain retention, one downside is that it puts the chain very close to the chainstay which could result in contact and chipping of paint
  • Because this frame was designed for full suspension, comes in smaller sizes, and has a downtube-mounted battery pack, there wasn’t room to mount a water bottle cage, consider a saddle adapter like this or maybe just a hydration pack like this
  • Depending on your inseam length and comfort with saddle height, you might have to cut the seatpost (with a hacksaw) to get it low because the rear suspension interrupts the seat tube, I cut it for this review because Paula wasn’t super comfortable with a high saddle
  • Both suspension systems offer locked or unlocked, sometimes it’s nice to have a middle “medium” compression setting… but at least they are both air and can be sagged to a range of rider weights and they also have rebound adjusters

Hi! I believe this bike is actually specced 250 watts for Europe but in the US they advertise 350 watts because it has a range of output power. Were you wondering because you live somewhere that has a legal limit like that?

Hi Court, I heard from a shop that women’s frames (this was about the haibike ‘creamsickle” you reviewed) are preferred by some men seeking a more nimble mountain bike. Did you find the women’s configuration less comfortable for you or perhaps not noticeably different than the unisex/male frames (with the bars and grips farther away)?
Nice update on that family vid!

Thanks Shaggy! I haven’t noticed a drastic difference on women’s bikes that couldn’t be simulated with a shorter stem or saddle slid forward. Yes, a shorter reach can change the geometry and make the bike feel snappier (just like shorter chain stays) but you can also kick the front tire easier. The geometry differences don’t seem that big, and I have seen some companies moving away from women-specific frames in favor of a more unisex color scheme. I guess I’m open to riding any Haibike because they use great parts, and I actually liked the orange Creamsicle colors. I hope this helps, my experience on this topic is somewhat limited and I wasn’t comparing back to back with an eye for ride difference, Bulls has so many mountain models and I felt that each one was a little bit different and unique.

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,

Will

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?

@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.
