Written Review

For this review I got some extra help from a young lady named Carla who knew how to ride a bicycle but had never tried an electric bike before. You can see here, her older sister Paula, and her father Victor in the video review above. My big takeaway from this experience was that young kids can have a blast with electric bikes but it’s worth spending some time on the control systems and shifting before setting out. While Carla picked things up extremely quickly and had a blast riding with the lightweight, smoother operating, Bosch Active Plus line motor on the BULLS TWENTY4 E, her older sister required a bit more practice and support to master the Bosch Performance Line CX motor, which feels zippier and can “surge” depending on how you pedal because it’s made for trail and mountain riding. With the TWENTY4 E, a young person can hop on and click the + or – buttons to add and subtract power in order to climb easier, keep up with their older siblings and parents, and feel empowered. This is one of the more premium kid’s electric bikes, and as such, it comes with a higher price tag. For $2.9k, you get one of the highest quality motors, a well-protected battery, integrated lights for safety, and a frame that was custom built for a smaller rider, complete with smaller 24″ wheels vs. 26″+ on adult sized bikes. The stand over height of the frame is roughly 24″ and this is what you can try to match to the inseam of your child. Will they be able to stand over this ~45.3 lb ebike easily? Carla had no issue, and the saddle height is adjustable so as your kid grows, you can keep their leg extension comfortable, even if they start to be more upright vs. leaned forward. One thing you cannot change however, is the limited 15.5 mph top assisted speed. Most full sized adult e-bikes can hit and maintain 20 mph or even 28 mph for Class 3 speed pedelecs. I do wish that you or your dealer could raise the top speed because that could make it easier for young riders to keep up with the rest of the family once they and you feel comfortable. Still, in Europe, almost all electric bikes are limeted to 15.5 mph, so it’s not a big trade-off. And there are some competing youth-oriented models that can only reach ~12 mph such as the Haibike HardFour 4.0 priced at $2.6k.

Driving the BULLS TWENTY4 E is the brand new Bosch Active Line Plus mid-motor. Compared to the older Bosch Active Line, this new motor weighs ~1.5 lbs less, is more compact in size, and offers a full-sized chainring vs. a reduction gear that spins 2.5 times for each crank revolution. In short, there’s a touch less drag when pedaling but chain retention might be slightly lower and response time may also be just slightly slower. I noticed and appreciated the Aluminum alloy chainring guard, which will keep pant legs and dresses snag-free while simultaneously keeping the chain on track. The motor is smooth and quiet but responds near-instantly so there’s no problem with unexpected starts or delayed overpower when it’s time to slow down and stop. Stopping is handled very well on this bike because Bulls opted for 160 mm hydraulic disc brakes with smaller levers that kids can easily grab and pull. Carla seemed to have no issue stopping during our ride and was regularly leading the pack with a huge smile on her face. She also handled gear shifting extremely well, easily going from low gears to start up to the higher gears in order to keep up with the pack. This electric bike is outfitted with a Shimano Altus 8-speed drivetrain and traditional trigger shifters near the left grip. The big button shifts to easier gears (for slow riding or climbing) while the small button shifts to harder gears (for faster riding and descending). One thing that I have always appreciated about the Bosch mid-motors is that they have fancy control systems that can detect user shifting and tell the motor to ease off, which reduces wear on the drivetrain. Considering that many young riders are new at shifting, and may be paying attention to balance and stopping, it’s great that the Bosch system can sort of protect itself and keep the bike from getting worn out prematurely. The motor casing-surround is made from black plastic which blends in with the bike frame. In my opinion, the bike is a bit more masculine in color, but Carla didn’t seem bothered at all by this (never mentioning it) and the fluorescent blue and green accents keep young riders visible to cars. Again, the lights, bright frame color accents, and white accents on the Schwalbe tires are all designed for safety because kids tend to be shorter and more difficult to spot by automobiles.

Powering this “kids” bike is an adult sized battery pack. The Bosch Powerpack 500 offers 36 volts and 13.4 amp hours for a total of ~482.4 watt hours of capacity. It’s enough to go probably 40 to 70+ miles on a single charge depending on how the bike is ridden, how much the rider weighs, and what level of assist is used. This battery can be charged on or off the bike and is filled by a quick 4 Amp charger that weighs ~1.7 lbs. I appreciate that Bosch has stuck with the same battery design since 2013 in the US because it means that many parents might be able to share their own batteries with their kids’ bikes… same goes for the charger. The battery casing has a big open loop at the top, making it easier and safer to carry around. It has an LED charge level indicator built into the left side, so you can tell how full it is when unmounted. And, it uses an ABUS locking core to be secured to the bike frame. ABUS makes high-quality locks and sells a whole range of security locks like u-locks, folding locks, and chains which can be “keyed alike” by using the code printed on the card that comes with your ebike keys. Okay, so one of the few question marks or complaints I have about this electric bicycle is that it’s expensive, which could make it difficult for many parents to justify if they expect their kids to outgrow it. One area where BULLS might have been able to save a couple hundred dollars and also reduce weight by ~0.5 lbs is to utilize the older Bosch Powerpack 400 battery. I think that it would have offered enough range for kids to match parents due to the lower top speed and lighter weight of this bike.

Operating this bike requires a few memorized steps to turn on and adjust power levels using the Bosch Purion compact display panel. This display cannot be removed like it’s bigger brother, the Intuvia, and it doesn’t have a micro-USB charging port built in, but maybe that’s for the best? It means that it’s tougher and less likely to get lost. The four buttons on this display are the power button along the top edge, a plus and minus key on the front left side, and a walk-mode button on the bottom. When you press the power button, the display comes to life very quickly and is faintly backlit so as not to distract but also stay useful when it gets dark outside. Once it’s on, there’s a battery infographic with five bars to designate fill at the top, a speedometer in the middle, a listing of assist levels that change as you press + and – and a couple of sub menus that can be accessed by holding the minus key (trip distance, total distance, and range). The range menu is neat because it updates as you select different levels of power. Other secrets include holding minus and tapping the power button to switch from metric to standard units and light activation which is done by holding the plus key for a few seconds. Considering that this is a kids bike and they nerfed the top speed, I think it would have been cool to make the lights auto-on and constantly on… just to increase safety. The final lower-edge button is for walk mode and you have to tap it and then hold + in order for it to work. This can be a very useful feature for pushing up hills, through grass, or getting home with a flat tire. You can change gears to increase or decrease walk-mode speed. All things considered, once this electric bike has been charged and turned on, it’s easy to use the different levels of pedal assist and reaching the button pad isn’t too much of a stretch, even for small hands. I feel that the plus and minus buttons could be improved by Bosch, to be easier to click near the lower edge and center (because they pivot at an angle) but Carla figured it out and did just fine. For those who wish to upgrade to the larger Bosch Intuvia display, many authorized dealers do offer a replacement/upgrade option which would make the display removable and just bigger (easier to see) with more responsive buttons and more complex menu options to explore.

For families that love cycling together, or kids who are excited to explore town, ride to school, and gain some independence… the BULLS TWENTY4 E offers a balanced, high-quality design with premium components and drive system hardware that should hold up very well. My guess would be that this bike will outlive individual kids as they grow and would maintain resale value or could be passed along to siblings. It’s not quite as bright as the Haibike SDURO HardFour 4.0 model mentioned earlier but the integrated lights and bright accents aren’t bad. I have a preference for Bosch motor systems over Yamaha (which the Haibike uses) but the Active Line Plus is very similar in operation and performance, it just allows the bike to go a bit faster. I love the adjustable kickstand, puncture resistant tires, and simple flick-bell that come standard, and appreciate that Bulls sells through a wide network of dealers who could help with fitting and post-purchase maintenance as well as accessorizing (helmets are important!) I’d like to thank Bulls for partnering with me on this post and the family who agreed to share their experience realtime on camera. Carla and her sister Paula did an amazing job and really let their personalities shine through. It made me smile and I hope that this review and the accompanying specs can help guide you towards the right choice of e-bike or regular bicycle for your special young ones.

Pros:

  • One of the few ebikes available, that I have seen in the USA, designed specifically for kids… it uses smaller 24″ wheels that lower the stand-over height, and a gentler motor with limited 15.5 mph top speed for safety
  • Higher quality components that won’t get worn out as easily, note the Schwalbe tires with puncture protection, Shimano Altus derailleur,
    SR Suntour suspension fork, and Tektro hydraulic disc brakes
  • Using hydraulic disc brakes vs. mechanical disc or linear-pull brakes means that kids don’t have to pull as hard to stop, the levers can also be adjusted to actuate closer to the grips so they are more comfortable if you have small hands
  • Excellent weight distribution because of the mid-drive motor and mid-frame battery pack, this improves handling and stability compared to a hub motor design or rear-rack battery
  • The battery pack and motor are well protected if the bike tips, Bosch is known for producing some of the most reliable electric bike systems on the market today and they offer a two-year comprehensive warranty with lots of dealers who can provide service
  • I’m not sure a rear-rack would fit on this frame without some creative tweaking but there are bosses for attaching such a system on the chainstays, I like the kickstand choice and location, and I appreciate the sturdy chainring guard that will keep the chain from dropping easily while simultaneously protecting pants from getting greasy or snagged
  • Very few mountain bikes have integrated lights but I think the reality of this bike is that it’s more of a “go anywhere and be cool” platform which utilizes some mountain design and hardware (such as the suspension fork and knobby tires), so the lights really improve safety and will help to keep smaller riders safe around automobiles
  • The new Active Line Plus motor from Bosch is very compact and lightweight at ~7.05 lbs vs. 8.8 lbs for the Bosch Performance Line motors, this helps to keep the overall bike weight down at ~45.3 lbs, making it easier to maneuver and ride for young people who might not be as strong
  • Normally, I complain about how the Bosch Purion display panel cannot be removed, but in this case that’s probably a good thing! It’s less likely to get lost by younger, possibly distracted, riders
  • I like that the bike comes standard with a little bell and that they used shorter crank arms and a shorter handlebar to really fit the rider and make it feel comfortable
  • Both wheels are connected using quick release and the battery is also easy to remove, this means you could store it without taking so much space, fix flats easily, or just break it into smaller lighter pieces for easier moving
  • The Bosch centerdrive motor system offers shift detection and this helps to reduce mashing and wear on the chain, rear sprockets, and derailleur… which is going to be extra useful if the young person riding isn’t as experienced at riding bikes, basically, it’s designed to protect itself
  • The locking core on the battery interface is from ABUS and it comes with a card which has a code you can use to purchase locks that will match and that way, you can use the same key for everything on your bike :)

Cons:

  • As much as I love the integrated lights, I feel like they should be programmed to turn on automatically and stay on because kids could easily forget how to activate them (hold the + symbol for a few seconds once the bike is on) or just get excited and ride off before taking that step
  • The official Bulls stock image shows the headlight mounted up on the handlebar which means it won’t bounce as much as if it’s connected to the suspension fork bridge and it will be easier to see… but the demo model I actually reviewed did not have the light up there, instead, it was mounted to the suspension fork
  • Very minor gripe here but the suspension fork isn’t very adjustable, you almost need pliers to twist the plastic caps to dial in rebound and both caps need to be adjusted in tandem to get it working perfectly… it’s more of a set it and forget it type of thing
  • Priced at $2,899 USD, this is not the kind of toy that most kids could save up for and buy themselves, it’s a big investment (and will last) but the kids might outgrow it, compared to adult electric bikes with similar hardware it is priced on target, but kids just don’t have as much money and I can see how some parents might be reluctant to pay so much
  • As kids grow up and become more comfortable on their electric bikes, it would be nice if parents or shops could adjust the maximum assisted speed from 15.5 mph to the full 20 mph that most adult Class 1 models can achieve, that way kids won’t be left behind
  • it only comes in one frame size but the 250 mm seat post offers some good fit adjustment, there’s also only one color which leans towards masculine… but the fluorescent colors help it to stand out vs. being all-black, reflective tires and reflective frame stickers would be nice
  • The Bosch Purion control panel uses big buttons that are easy to reach but I have found that they don’t click as reliably if you press near the lower edge or center because they pivot at an angle towards the screen, this could be confusing, distracting, or frustrating for a younger rider… press near the screen for best results
  • As much as I love the high-capacity Bosch Powerpack 500, this pack does cost more, and it feels like they could have saved some money and just a bit of weight by going with the older Powerpack 400 battery

So I have been researching e-bikes for around town commuting and fun on local trails in Bellingham, Washington which is a rather hilly spot. I have taken test rides on 14 bikes from Kalkhof, Rad, EMotion, Bulls (3), Focus (2), Cube (3), Riese & Muller(3). I have read and watched the video reviews on this site for all the above and at least another dozen more. I do have a bias in favor of German engineered vehicles and have been driving a Mercedes wagon for the past 25 years, currently an e500 4matic wagon.

After lots of careful consideration, I put an order in for a Riese & Muller Nevo Nuvinci GH It comes with the Bosch CX they also have an HS (high speed) with a Bosch Performance motor. They are just under $5000. Riese & Muller bikes come very complete as regards accessories (lighting, fenders, locks, racks) as well as really top flight peripherals (brakes, tires, rims, drive systems, grips, saddles, suspensions, etc.). Build quality is outstanding, designs are interesting and well thought out, engineering seems to be thorough and complete.

I tried both the CX and the HS models in both Riese & Muller as well as Bulls. I found that the CX higher torque performance on hills is something I would be making good use of all the time, whereas the HS version while capable of going up to 28mph with power assist, requires a lot more pedal effort past about 22 mph due to exponential increase in wind resistance...enough to make me less eager to go that fast, especially when it means sacrificing hill climbing ability.

Right after ordering the Nevo, I ended up getting a smoking hot deal on ebay for a really nice Cube (another German brand) so that is what I'm riding now while I wait for the R&M to be delivered. Then we will have two nice bikes for my wife and me to go riding together.

The Cube is great but the Riese & Muller with the Nuvinci drive and Gates carbon fiber belt drive is a very clean, low maintenance option that has a ton of appeal to me. There is some efficiency loss in the Nuvinci drive so you might want to look at the GT Touring models from them as they have traditional gear cassettes and derailleurs. That will give you less frictional power loss for that extra little bit of oomph.

Count on it taking on month minimum, unless you are lucky enough to find a dealer who has just what you want. They offer lots of options and produce them in Germany to your specs. Add in cross Atlantic shipping, dealer set up and delivery an you have a wait that will try your patience. From all reports well worth it though.

Let us know what your decide on.

DAHON MATRIX 26" folding ELECTRIC mountain bike with super quality, hill climbing BMC 600watt V2 motor, Cycle Analyst 2.1, upgraded controller, Thudbuster, extras. I bought a Bulls full suspension ebike, so it is time to let this go.

Most ebikes are set to 15-20amps of power with a cheap controller. They will not get you up a hill or be very fun on a trail. My bike's electronics are upgraded to give you lots of power....and 26mph.

If the ad is up, it is still available. $850 CASH ONLY, no trades. In Thousand Oaks. Email me your name and phone number and a day and time you want to see it, and I'l get back to you asap. Will update or delete below items if sold.

DAHON MATRIX 2009 med. size 26" folding MTB w/ Thudbuster seat post, front suspension fork, Origin 8 Spacebars for comfortable ride. Rear rack with Topeak MTX bag w/panniers. Heavy duty MTB tires. Quick release front wheel. Folding pedals. Cannondale heavy duty kickstand. Folds easily with included hex wrench tool, I hardly ever folded it.
Converted to ebike. you can easily remove the battery box and still pedal with the 9 lb. motor freewheeling. Disc brakes could use new pads.

Will consider selling bike only (without rear wheel)

BMC V2 speed 600 watt motor purchased from Ilia Brouk (ebikessf.com) w/ 7 sp. freewheel. 2 torque arms on rear motor axle.

Great geared rear hub motor. link on BMC motor: https://endless-sphere.com/forums/viewtopic.php?f=4&t=22103
Battery and controller are mounted in center triangle for optimum, low center of gravity. Much better than a rear rack battery mount like Prodeco.
CRYSTALLYTE 36-72v analog controller, upgraded to 35 amp , CLYTE full Twist Throttle (like a motorcycle)
Cycle Analyst 2.1 battery aHr meter/speed computer w/ limit switch to conserve battery.
Ping 15ah 36v Battery with BMS set to 40amps continuous- mounted in custom box in triangle. Comes with charger.
The battery had a good, long life but now goes only about 4-6 miles, depending on how much you pedal. Will need a new battery to go far. I can recommend this : http://www.ebikes.ca/b3614lim-dt.html# an excellent, matched battery for $485 shipped.

Other good battery options are available too.....Ping still makes very good batteries and will make a high current BMS.

Original cost:
Bike: $750
BMC Motor and controller, throttle, Cycle Analyst 2.1 package: $900
Thudbuster seat post: $120
Spacebars $40
Rack and Topeak bag $125
Cannondale heavy duty kickstand. $40
Ping 15 aHr Battery $450

Sell all for $850 FIRM. Buy the brand new battery for $485 and you have a 26 mph, 30-40 mile range, suspension hill climber for under $1350.

I have a Bulls FS Enduro with the Brose motor for a little over a year and have never broke the chain and am just about to replace it as it is just out of spec. I ride this bike A LOT on rugged mountainous trails. Also have a Haibike for over 2 years and have only broke a non-ebike chain.

I always carry pins & a link, along with patches, replacement tube, inflator, etc, and have never had to use them for myself but have bailed out many others on the trail that where unprepared. It's been sort of like a reverse "Murphy's Law".

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?

Scooteretti
2 weeks 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.

regards,

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.

Yeah, I agree with Larry, Suntour isn't quite as cool as RockShox and neither are as cool as Fox in my book, but they are offering some great quality now... perhaps their reputation is a bit lower because they also sell a lot of the lower-end forks. In my opinion it depends on the hardware you're looking at. This video was shot in Palos Verdes near LA by the way, not Palo Alto, I don't know what Victor does for work

Yeah, she wasn't as comfortable riding so we set the seat height low so she could easily put her feet down for stability. Ideally, the seat would be higher so that she could get full leg extension. This was also her first time riding an ebike, it seemed like her little sister was more comfortable so maybe she rides more frequently?
