Fat tire electric bikes offer a perfect blend of technology and adventure in my opinion… an unpowered fat bike is fun, sure, but the added weight and drag of larger wheels and tires means that most people are limited in how far and long they can actually enjoy the ride. Furthermore, if you actually do seek out the snowy fields and sandy beaches that those fat tires yearn for (as I did in this video review), they can become uncomfortable because the terrain isn’t always smooth! And once you’ve added suspension there’s increased weight and often some bob as you pedal along. So that’s where this whole full suspension fat tire electric bicycle concept fits in… In many ways, it isn’t that surprising right? We see full suspension motocross bikes all the time, in fact I think most motorcycles (even road bikes) offer full suspension. But they’re loud, heavy and usually illegal on bike paths, mountain trails and beaches. The Monster E FS delivers something special in this domain, an ebike that’s both capable of handling a wide variety of terrain and usually well accepted there. It’s made with some of the best consumer/performance level hardware on the market as of this review (Magura brakes, Shimano Deore XT derailleur) and is driven by one of my favorite motor systems around, the Performance Line CX from Bosch.

With internally routed cabling, a sporty paint job and some additional metal shields in place, the battery pack truly blends in on this bike. And despite offering about 25% larger battery capacity than the previous Powerpack 400, the battery form factor is exactly the same and it weighs less than a half a pound more! You can still charge it on or off the bike and it’s even backwards compatible so if you already own a Bosch powered electric bike from the 2014-2016 timeframe you can swap them out or carry an extra along for increased range. Having tested and reviewed some of the other BULLS electric bike models recently, those with the more tightly integrated Brose battery/motor system, I gained renewed appreciation for how beautifully and simply the Bosch pack clicks in and locks. You don’t have to worry so much about bumping the key if you accidentally leave it in and you don’t have to physically twist the key to lock the pack… just when you unlock it, and this increases security. Going from there, the control panel and button pad that let you interact with the battery and motor are both very well done. You can switch assist levels on the fly without lifting your left hand and compromising your grip… just a bit of thumb work. And you can also cycle through display readouts this way. One of my favorite menus is range approximation because it dynamically updates depending on how you’re riding, what assist level you’ve selected and how much battery capacity remains in the pack. This is the sort of feedback that ensures you won’t get stuck way out in the backcountry with a depleted pack. This is especially relevant because the battery indicator only shows five bars vs. 10 on some other bike displays. That’s one of my minor gripes.

If you do get stranded on this ebike, no worries because it has a wide range of 11 gears for pedaling. And in the electric bicycle world, that’s quite a few! I found that the bike was operable on human power alone (especially on pavement) and enjoyed the rolling momentum that the tires offered once up to speed. It was easy to handle the bike on all terrain types we tested thanks to longer mountain bike style bars with locking Ergon grips and I appreciated the remote lockout on the Bluto suspension fork. Many of the hardware components chosen for this bike are of a higher build quality and designed to be light weight. At just under 56 lbs… this is what I would consider very light given how large it looks and the fact that it’s a fat bike with full suspension. It is missing a few things though, no kickstand means it could tip into your fancy car in the garage more easily and no bottle cages mean you’ll need a hydration pack. Part of me yearned for throttle on demand operation in addition to pedal assist but I recognize that this would change the class of the bike, exhaust the battery much faster and ad clutter to the cockpit. It might also delay how quickly the motor cut out resulting in sketchy performance on difficult technical terrain. Yes, this is a hard core capable bike that would handle serious riding. Bosch offers one of the most responsive, zippy feeling drive systems around and if you’re in the highest level of assist (there are four to choose from) it works very well, almost responding like a throttle without requiring exhaustive pedaling force. Almost as soon as you’ve stopped pedaling, the motor also stops and that’s a great feeling… but it works the other way too, responding especially fast as your cadence increases (ie. shifting to lower gears for climbing or maneuvering through an obstacle course of rocks, ice or fauna).

I honestly don’t have many complaints to share about this ebiket. Its great that given just how custom and unique a build it is, BULLS was able and willing to manufacture two sizes. Their two year comprehensive warranty is excellent and despite the perceived higher price point, I actually think you’re getting a good deal relative to what other companies charge for similarly specced builds using less interesting drive systems. Consider their hardtail Monster E model if you’re looking to save $1,000 and don’t mind a stiffer rear… In that case you could always add a seatpost suspension as a compromise. As someone with limited storage space, I tend to choose one high quality bike to “do it all” and that’s exactly what this offers. You get comfort, longer lasting parts and a bike that won’t quite. In a world with more and more 3″ tires it’s great to see an actual full sized 4″ wide fat tire bike that’s done so well. Powerful hydraulic disc brakes, thru axles, a tapered head tube and a custom replaceable metal skid plate make this bike extra tuff. Not to mention the chain tensioner with fully surrounding guide and narrow wide teeth. I love that you can easily and quickly take both wheels off for compact storage and transport and am glad that BULLS opted for the four bar rear suspension design to optimize traction, reduce bob and lower as much weight as possible. It’s a great bike, lots of fun and easy to use. Compared with some other full suspension fat ebikes I’ve tested, it offered a wider range of pedaling speeds while still supporting me with motor power. The motor is just more capable at high RPM and that’s how I prefer to pedal, it happens naturally as I shift down approaching hills, I don’t feel like the motor quits on me. As someone with sensitive knees, this has been one of my favorite fat bikes so far and I’m optimistic about how it could be used on so many terrain types and in so many seasons. Big thanks to Bulls for partnering with me for this review.

Pros:

Custom paint and decal job that includes the frame, rear swing arm and pivot point, suspension fork and rear suspension housing! EVERYTHING matches and looks awesome
Sturdy 15 mm thru axle on the front with 12 mm at the rear, keeps the larger heavier wheels tight and responsive, both offer quick release which is handy for repairs or simply transporting the bike since it’s so large
In addition to removable wheels, the battery pack and display console are also removable… I love that the battery can be charged on or off the frame and is backwards compatible with the older Bosch Powerpack 400 batteries
Top-end components from Magura, Rock Shox, Schwalbe, Ergon and Shimano that will hold up in off-road conditions and are backed by the BULLS comprehensive two year warranty
I was impressed that even with the larger capacity battery, full suspension setup and fat tires this bike weighs just ~55 lbs and I love that it comes in two sizes for improved rider fit
Most of the weight is positioned low and center across the frame, this improves handling and since it’s a mid-drive, reduces unsprung weight compared to a hub motor
You get 11 gears so pedaling feels comfortable at a wide range of speeds… even if the bike is turned off and the Bosch motor offers shift sensing to reduce wear
I love that they included a chain tensioner with a full hood to act as a guide (clearing debris and mud), it should reduce kickback from the rear swing arm and the narrow wide tooth pattern is designed to reduce chain slip
Punched out rims reduce weight, look cool and might add some cushion to the tires for improved comfort and traction at lower PSI
Sturdy metal motor cover… like a louvered push guard on a truck, designed to protect the sensitive bits but be replaceable if you encounter major damage
This is the only Bosch powered full suspension fat bike I’ve seen to date and is definitely my preference in terms of power, zip and responsiveness compared to Yamaha and other mid-drive systems, the chainring spins fast and is super quick to start and stop which is great for unstable terrain
The Bosch Intuvia display panel is large and easy to read, simple to use and doesn’t require that you reach far while holding the grips to operate, a remote button pad with tactile feedback is mounted very close to the left grip… I also like that the display panels has a Micro USB charging port built into the side for maintaining your portable electronics

Cons:

The bike worked fine in the sand but requires pedaling (Class 1 pedal assist) and there are times when it’s nice to have throttle power just to power through soft terrain or get started again after stopping… the benefit of Class 1 is that it’s allowed on more trails vs. Class 2 throttle powered ebikes
The rear suspension joints and shock take up the space where a bottle cage or other accessory mount might have been fit… you can’t add a rear rack easily (unless you compromise with a beam rack) so you might end up using a hydration pack all the time
The Bosch battery doesn’t blend in with the frame quite as nicely as the Brose battery on some other BULLS ebike models but it is easier to remove and comes in a higher ~500 watt hour capacity here for longer range rides, I like that the built some metal plates around the base to help it blend in… and added those matching yellow stripe stickers
This is an expensive electric bike… you’re getting a lot of high quality hardware but if you ride it near saltwater without rinsing it afterwards or if you’re on other corrosive terrain frequently (salted snow?!) then it will wear out more quickly, there’s a trade-off with bikes like this where you can get one that’s pretty good for half the price and then completely replace it in a year or two vs. one very nice one that you need to care more about to extend

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 caution anyone from getting a proprietary system. I want to be able to fix things myself rather than rely on a dealer.

Thread: frustrated rant: the more i learn…

rich c

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.

Correction. I’m not sure how to amend the post. It should have read.
I zip peak fs 3 and bought a bull evo fs3 plus.
I’m considering a bulls evo 45 ds 3 plus

Generally speaking, low end torque and top end speed are a trade-off. You can have one or the other but not both.

Thanks for stopping at the stop sign unlike the other guy. Once anyway. You can't get angry with cars if YOU don't follow the rules of the road.

I will go for one when they make a dual suspension with a 65 head angle, 160 Forks and a dropperpost .

Great bikes but what's with the random stop signs? In Aus we never have stops signs on the "main" road of a T junction, only for the side roads.

Welcome to America?! I don't know, each state and city is a bit different but we are starting to get more roundabouts because they cause fewer accidents and speed up traffic

Wow, you live in Nepal?! That's awesome, do you enjoy hiking in the mountains? I cannot say whether Bulls will bring this product to Nepal, but perhaps you could hire a company to import one for you?
