I’ve examined just a few totally different Cyrusher electrical fats tire bikes over time, and so they all have the identical fundamental qualities: The match and end won’t match the professionals, however the bikes supply a enjoyable serving to of ridiculous excessiveness. The Cyrusher XF900 full-suspension fats tire e-bike may simply be probably the most extreme but, in all one of the best methods.
The Cyrusher XF900 launched late final 12 months and is even bigger in individual than I had anticipated from the images. It doesn’t simply look large – it is large.
It’s overbuilt so as to take it nearly wherever and throw it at nearly any terrain.
Between the fats tires and full-suspension, the Cyrusher is principally begging you to lastly go away the asphalt behind and do some actual exploring.
Whereas I examined it with a good quantity of commuting-style using, plenty of my adventures didn’t simply head for the paths – they left the paths behind fully.
Check out how the bike fared in my video overview beneath, then hold studying for my full overview!

An additional serving to of elements
The Cyrusher XF900 comes just about totally loaded.
The rear hub motor is nominally 750W, however they’ve overloaded it to tug 1.5 kW of peak energy. On a lighter e-bike that’d be loopy excessive, although on the heavy XF900 it’s simply fairly excessive. It’s not going to throw you off the saddle, however you’ll wish to ensure you’re holding on tight if you blip the throttle or have interaction the pedal help.
A cool characteristic that I don’t see fairly often is that the throttle’s energy stage is definitely tied to the pedal help stage selector. With 5 ranges of pedal help, when you begin in stage 1 and mash the throttle to 100%, you’ll expertise a delicate takeoff. In pedal help stage 5, the throttle provides you that jolt of energy that many riders are on the lookout for. Any quantity in between offers an more and more extra enthusiastic throttle response.
With a strong e-bike like this, with the ability to tone down the throttle is a pleasant characteristic. It’s helpful if you wish to do low-speed maneuvering in addition to when letting a pal strive the bike if you aren’t so positive how acquainted they’re with highly effective e-bikes. I can go away it in stage 1 or 2 till I see that they aren’t going to whiskey throttle their means right into a brick wall.
On the battery aspect of issues, the corporate doesn’t fiddle with puny 48V 10Ah batteries and so they don’t even waste time with a 14Ah pack. They go straight to the 48V 17Ah pack to provide one of the best vary. That’s the type of huge battery you want if you’ve received a strong motor and controller. They nonetheless promote the foolish vary of 100 km (62 miles), however that might solely be doable on pedal help stage 1 and with a tailwind. Count on a throttle-only vary of a 3rd of that, and a pedal help stage 3-ish vary of perhaps simply over half the max said vary. This can be a heavy bike with plenty of rolling resistance, so it’s not going to be terribly environment friendly.
Off-road using prepared
As I discussed within the opening, this e-bike is admittedly designed for exploring the unexplored.
The enormous fats tires and suspension make it straightforward to hit obstacles you’d by no means think about on a hardtail e-bike with 2″ tires.
Each the entrance and rear suspension are center shelf; they aren’t prime notch elements like we discover on e-bikes that value practically twice this a lot. However they’re adequate for leisure using, which is strictly what I used to be on the lookout for.
When the using received significantly rutted out or technical, I undoubtedly needed to come out of the saddle. The suspension simply isn’t plush sufficient for the actually tough stuff. However by and huge I might keep planted and have a terrific journey via grime, gravel, excessive grass, and a few mild sand.
The highly effective motor and the tires’ skill to just about float over something means you aren’t restricted to trails. I did loads of using via tall grass fields the place I had no thought what I used to be using over, however apparently it didn’t matter. I couldn’t see the bottom however I might nonetheless roll proper over every part.
The one factor getting in my means was the pair of derailleurs to snag grass and weeds. That is considered one of only a few e-bikes to sport a number of entrance chainrings. The 21-speed setup is attention-grabbing, however it feels pointless.
The benefit of all of these gears is totally on the low finish, the place you’ll be able to drop into decrease gears for extra torque throughout hill climbing. However with a strong motor like this, you don’t actually need to drop so low because you’ll be climbing at sooner speeds anyhow.
The elevated granularity additionally makes it straightforward to seek out the right cadence. However once more, that simply feels pointless on such a strong e-bike. Possibly the purists will benefit from the elevated gears, however I just about left the bike in a single gear the entire time: the best one.
That’s as a result of the Cyrusher XF900 is simply so rattling quick. It tops out at 28-ish mph (45 km/h), and it will get there on throttle-only using or with pedal help. Technically it’s not a category 3 e-bike if it may well surpass 20 mph on throttle, however nobody stopped me to ask and I didn’t volunteer that information to anybody.
At these speeds, the bike is an equally succesful highway warrior and path tackler. I don’t usually hit prime pace on the path, however the open highway provides me the room I must run quick. Again on the paths, if I hit the mid-20s of mph, I think about that fairly darn quick.
Any complaints?
Nothing is ideal, and I’ve just a few gripes concerning the Cyrusher XF900.
The fenders are as low cost as they arrive, although I get that fats tire fenders for a full-suspension e-bike are a tough nut to crack. The excellent news is the rear doesn’t flop an excessive amount of as a result of the rear rack holds it in place. The entrance will get a bit floppy, however what are you able to do? That’s low cost plastic for you.
Subsequent, the entrance headlight is okay however the rear tail mild frustrates me. It isn’t a typical e-bike mild that runs off the primary battery. As an alternative, its a saddle mild that has its personal battery. Meaning two major downsides: the battery will want considerably frequent changing when you journey at night time usually, and it will likely be blocked when you put stuff on the rear rack. I additionally discovered myself generally clicking the button once I moved the bike by lifting beneath the saddle. If I didn’t discover that I by chance clicked on the sunshine, it might run for hours in the course of the day and drain the battery by the point I would like it at night time.
A torque sensor additionally would have been good. The cadence-based pedal help sensor is okay, however if you’re enjoying within the huge leagues you begin to wish to see these nicer elements that make the using expertise only a bit extra snug and responsive. At this worth, a torque sensor would have been a pleasant contact.
Lastly, I’d say the value is a troublesome promote. At $2,799, that is one costly e-bike. You actually get loads: excessive energy, larger-than-average battery, quick speeds, full-suspension, hydraulic disc brakes, included rack and fenders, and so forth. But it surely doesn’t come low cost.
It’s truly evenly priced towards a number of different full-suspension fats tire e-bikes in its class, however it’s important to actually need all of those options to write down a test that huge.
From my time on the bike although, I can undoubtedly say that that is one hell of a journey. Having the ability to discover every part from the concrete jungle to an precise jungle, and doing it for greater than just some miles, is an expertise that I hope everybody can have sooner or later.
