I’ve tested a several different Cyrusher electrical extra fat tire bikes above the many years, and they all have the identical standard attributes: The fit and finish could not match the professionals, but the bikes supply a fun helping of absurd excessiveness. The Cyrusher XF900 comprehensive-suspension fat tire e-bicycle may well just be the most too much nonetheless, in all the finest methods.
The Cyrusher XF900 launched late last year and is even larger sized in particular person than I had envisioned from the images. It does not just seem substantial – it is massive.
It’s overbuilt so that you can consider it just about anywhere and toss it at just about any terrain.
Concerning the excess fat tires and full-suspension, the Cyrusher is in essence begging you to at last leave the asphalt driving and do some serious discovering.
Though I examined it with a honest sum of commuting-type driving, a large amount of my adventures did not just head for the trails – they remaining the trails behind wholly.
Consider a glance at how the bicycle fared in my video overview underneath, then continue to keep looking through for my full evaluation!

The Cyrusher XF900 arrives very a great deal entirely loaded.
The rear hub motor is nominally 750W, but they’ve overloaded it to pull 1.5 kW of peak power. On a lighter e-bicycle that’d be outrageous high, although on the major XF900 it’s just pretty superior. It’s not going to throw you off the saddle, but you are going to want to make certain you are keeping on restricted when you blip the throttle or engage the pedal assist.
A amazing feature that I never see quite frequently is that the throttle’s ability level is truly tied to the pedal assist amount selector. With five concentrations of pedal aid, if you commence in degree 1 and mash the throttle to 100%, you are going to encounter a gentle takeoff. In pedal guide amount 5, the throttle provides you that jolt of electric power that quite a few riders are on the lookout for. Any number in concerning delivers an ever more far more enthusiastic throttle reaction.
With a highly effective e-bike like this, staying equipped to tone down the throttle is a awesome characteristic. It is practical when you want to do small-speed maneuvering as nicely as when allowing a good friend test the bike when you are not so confident how familiar they are with effective e-bikes. I can depart it in stage 1 or 2 right until I see that they aren’t likely to whiskey throttle their way into a brick wall.
On the battery side of points, the enterprise does not mess all-around with puny 48V 10Ah batteries and they never even squander time with a 14Ah pack. They go straight to the 48V 17Ah pack to give the best variety. Which is the form of significant battery you will need when you’ve obtained a powerful motor and controller. They even now promote the silly vary of 100 km (62 miles), but that would only be probable on pedal aid stage 1 and with a tailwind. Anticipate a throttle-only variety of a 3rd of that, and a pedal aid amount 3-ish variety of perhaps just above fifty percent the max mentioned variety. This is a hefty bicycle with heaps of rolling resistance, so it is not likely to be terribly efficient.
Off-highway driving completely ready
As I stated in the opening, this e-bike is really built for discovering the unexplored.
The huge fat tires and suspension make it straightforward to hit hurdles you’d hardly ever think about on a hardtail e-bicycle with 2″ tires.
Both of those the entrance and rear suspension are center shelf they are not prime notch pieces like we obtain on e-bikes that expense approximately 2 times this substantially. But they are excellent sufficient for recreational riding, which is exactly what I was on the lookout for.
When the driving got critically rutted out or technical, I undoubtedly experienced to come out of the saddle. The suspension just isn’t plush enough for the truly tough stuff. But by and big I could remain planted and have a terrific ride by way of filth, gravel, superior grass, and some gentle sand.
The impressive motor and the tires’ means to very a lot float more than anything implies you aren’t constrained to trails. I did a great deal of using through tall grass fields where by I had no thought what I was riding more than, but evidently it didn’t subject. I couldn’t see the ground but I could still roll appropriate over anything.
The only matter getting in my way was the pair of derailleurs to snag grass and weeds. This is 1 of quite few e-bikes to sport several entrance chainrings. The 21-velocity set up is intriguing, but it feels unnecessary.
The advantage of all of those gears is mainly on the small conclude, exactly where you can drop into decreased gears for additional torque for the duration of hill climbing. But with a potent motor like this, you really do not genuinely require to fall so small due to the fact you’ll be climbing at more rapidly speeds anyhow.
The improved granularity also can make it effortless to find the fantastic cadence. But all over again, that just feels unnecessary on this kind of a impressive e-bike. Possibly the purists will get pleasure from the increased gears, but I quite significantly remaining the bike in a solitary equipment the whole time: the optimum just one.
Which is since the Cyrusher XF900 is just so damn speedy. It tops out at 28-ish mph (45 km/h), and it receives there on throttle-only driving or with pedal assist. Technically it is not a class 3 e-bicycle if it can surpass 20 mph on throttle, but no one particular stopped me to ask and I didn’t volunteer that information to any person.
At individuals speeds, the bicycle is an similarly able street warrior and trail tackler. I do not usually hit top speed on the trail, but the open street presents me the home I need to run rapidly. Again on the trails, if I hit the mid-20s of mph, I look at that really darn fast.
Almost nothing is perfect, and I have a couple gripes about the Cyrusher XF900.
The fenders are as low-priced as they appear, nevertheless I get that extra fat tire fenders for a total-suspension e-bicycle are a tough nut to crack. The great information is the rear does not flop too substantially since the rear rack retains it in put. The entrance will get a little bit floppy, but what can you do? Which is low-cost plastic for you.
Upcoming, the entrance headlight is fine but the rear tail gentle frustrates me. It isn’t a usual e-bicycle gentle that operates off the key battery. Rather, its a saddle mild that has its personal battery. That means two most important downsides: the battery will require to some degree repeated replacing if you ride at evening generally, and it will be blocked if you place things on the rear rack. I also identified myself often clicking the button when I moved the bike by lifting under the saddle. If I did not detect that I unintentionally clicked on the light, it could operate for several hours during the working day and drain the battery by the time I have to have it at evening.
A torque sensor also would have been great. The cadence-dependent pedal guide sensor is good, but when you are playing in the large leagues you begin to want to see all those nicer components that make the riding working experience just a little bit far more at ease and responsive. At this cost, a torque sensor would have been a wonderful contact.
Lastly, I’d say the cost is a difficult provide. At $2,799, this is one high-priced e-bicycle. You definitely get a whole lot: higher electric power, greater-than-common battery, quickly speeds, whole-suspension, hydraulic disc brakes, provided rack and fenders, etc. But it does not arrive inexpensive.
It is really evenly priced towards several other comprehensive-suspension excess fat tire e-bikes in its class, but you have to actually want all of these functions to produce a examine that massive.
From my time on the bike although, I can undoubtedly say that this is 1 hell of a trip. Remaining ready to examine every thing from the concrete jungle to an precise jungle, and undertaking it for far more than just a couple of miles, is an encounter that I hope everyone can have at some point.
