Summary

  • A tough, sporty looking, high-quality, kids electric bike that can reach ~15.5 mph with four levels of pedal assist, smaller wheels keep the frame low and approachable
  • Premium accessories including tires from Schwalbe, a Shimano Altus 8-speed drivetrain, and Tektro hydraulic disc brakes that are easy to pull for small hands
  • Excellent weight distribution for improved handling and balance, the motor and battery pack are well protected and come with a fantastic two year warranty
  • Integrated lights can keep small riders seen by cars day or night but it would be nice if they automatically activated and stayed on, the top speed cannot be raised, it's expensive

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

1 option to reduce lifting weight is to put the battery in a back pack. That's almost 6 pounds off the weight of the Bulls bike. I'd feel better about the security of the battery with this as well.

I have been zeroing in on getting a BULLS SIX50 E2 Street bike which uses the Bosch performance line motor. One concern I have is the weight as I take the bike on mass transit and you have to lift it up onto a hook and this bike I believe is 55 pounds (based on EBR review and my test ride)

Another bike that I am interested is the FLK roadster which claims to weigh 46 pounds and uses the Bafang Max Drive.

Im trying to understand how these two motors compare from real rider experience and not comparing their specs. Court reviewed the Bulls bike and Brent reviewed the FLX. said: "Its not weak, ... it gives you enough power to get up modest hills". This statement seems to be in context of the Blade. And I have read one other motor review that wasn't impressed with the Max drive.

Court/Brent or anyone that has tried these two bikes: Are you able to give me your feeling about how these two motors compare from actual riding.

Thanks,

Rex

Battery capacity and weight have more to do with range than motor. Brose also makes nice (quiet) mid-motors.

Check out Bulls' lineup. You're likely interested in their eSpeed or urban bikes http://www.bullsebikes.com/ebikes/ Some come with 650wh batteries, which should get you the range you want

Things that we want to know from you on the things that you prefer;
1. Price bracket.
2. Drop bars or not. If you want drop bars then the list is limited to about 5 ebikes.
3. If non drop bars, do you prefer hub drive vs mid drive. The drive train on hub drives tend to last a long long time (shorter life than normal for mid drives), If you get Bulls that has Bosch power with chain ring having 22 teeth count (equivalent to 56 teeth) then the drivetrain may have longer life compared to other mid drives.

For a road style e-bike, I would look at the Trek CrossRip+, Bulls Dail-e Grinder, and the Giant Road-E+ 1. These will do 50-62 miles as long as you aren't only using the highest level of assist. The Trek and Bulls come with a rear rack, and the Bulls has fenders and front suspension as well.

I read zero reviews when I bought my first ebike. Just bought a Sondors fat bike for $500 off Craigslist. It has over 1,700 miles on it now. Second ebike purchase, I drove 3 1/2 hours to a dealer that only sells ebikes. Intent was to buy a Bulls mountain bike. Rode 4 bikes, liked them all, but bought a demo Haibike, over 2,000 miles on it. Recently bought a tad pole e-recumbent trike, sight unseen, unridden, only based on reviews. After riding it for the first 3 to 4 times, I still hated it. Certain I would have to sell it on Craigslist. But I'm stubborn when I spend $3,500 for something. I made new seat mounts for a better position, bought shorter cranks, changed a couple options in the controller, and built up some new muscles for that style of trike. I have almost 400 miles on it now, and do enjoy it for crushed stone rail trails. Still don't enjoy it a lot on road travel. So with these miles and experience, I'm a strong advocate for LBS. NOTHING will replace demo time in the saddle. Secondly, sounds like you will be fine as a bike mechanic. Not that common for ebike riders. Most on-line purchases require the owner to do the wrenching when a failure occurs.

Can someone explain to me how Bulls gets a fatbike-compatible chainline on the Bosch motor? I imagine there's some serious hackery going on because, unlike Yamaha, it's far from obvious how to get a suitable (e.g., 75mm) chainline on a Bosch motor.

I'm doing a 36 mile round trip on a Bulls Lacuba e45 speed pedelec. I only have about 2.5 miles of open road before I have to drop my speed and mix with congested traffic. With a tail wind I can average 18mph and use 50-60% of my 650 wh battery. If I have a headwind I use even more battery. Based on your new commute I'd think you'd need a 1000 wh battery, I've heard that it's easier to get up to the magical 28mph with a rear hub motor with my mid drive 23-24 is the sweet spot after that you have to really work.

I don't believe I have met your 'old' wife so how would she know .;)

No this sudden outburst from me was prompted by reading a review which claimed to be "a useful analysis of hub vs mid drive setups". There was a number of long paragraphs extolling the virtues of the hub drives and very little on the mid drives. It mentioned a problem of breaking chains which got me thinking. (dangerous)

( for the last 15 months I have ridden a Bulls MTB)

You make it sound like 1kWh is enough... I'm not sure it is. If I had to estimate the amount of 18650 cells you could stick into the triangle of a typical frame, I'd estimate available space to be worth 2.5-3kWh (@36V of course) if we were to incorporate dual powertube-style batteries (R&M Supercharger-style). If I had to guess how many cells I could stick into my Salsa Blackborow, the answer is 'a huge amount'. And without the price distortion that Bosch, Yamaha and others introduce to the battery market. Charging $700 for 500Wh (basicaly a bunch of 18650 cells and a proprietary magical BMS) is weird.

And BTW the battery you link to is just a bespoke battery, it will not clip into your frame. There are Yamaha-compatible aftermarket batteries but https://www.ks-bikes.de/Beltrona_f%C3%BCr_Yamaha_36V_612Wh_17Ah_Sduro_Rahmen_Akku_E-Bike_Pedelec_1.html -- I'm not sure it's worth it.

@Dmitri Thank you for all that info. So for aftermarket batteries it pretty much comes down to where you can carry it.

I found this while searching for Yamaha batteries: https://ebikemarketplace.com/products/sea-lion-36v-battery?variant=30491286533&_vsrefdom=adwords&gclid=EAIaIQobChMIrpiv1IzJ2wIVzSWBCh0f0A30EAQYASABEgLHl_D_BwE

It has a key but not sure if it’s designed to click in to the Haibike frame. 756 Wh would be very nice.

Since the technology is already available I don’t understand why manufacturers keep producing underpowered ebikes. Stromer gets it. Juiced gets it. Bulls is getting there.

And I just bought an underpowered Haibike FullNine 6 (Yamaha), since I was able to get a great deal on a 2017 closeout. But I would have preferred a Bulls with the 650 Wh battery.

ElectricBikeReview.com

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

ForbinColossus sun tour might be cheaper but they make some decent shocks, I still have one of their rear shocks on my Harbike Fullseven S RX, it’s outstanding, at least for the terrain where I live at, but I have heard horrible stuff about the Magura shocks, but they do make the best brakes in the business

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?

I think the Bosch Active Line Plus offers 50 Nm of torque and the standard Active Line is 45 Nm. Mid-drive motors tend to offer more torque than hub motors because you can switch gears... can, but if you don't actually shift properly it can result in less effective torque ;)
