Cyrusher XF900

Cyrusher e-bikes are distinct, with unusual frame designs and bright colors, and the XF900 is no exception.

This full-suspension machine sports a dirt bike-inspired look. Cyrusher claims the 750W XF900 is a powerful all-terrain e-bike for challenging terrain. This review will put that claim to the test and see how the bike stacks up against the competition.

What Is the Cyrusher XF900?

The XF900 is a large e-bike with a motocross-inspired look provided by the dual-crown suspension fork and large knobbly tires.

Cyrusher chose a 750W Bafang motor, which can power the XF900 to 28mph with pedal assist or over 20mph using the throttle.

My first impression of the bike was underwhelming. The components are primarily entry-level and offer limited performance and function beyond recreational riding. The XF900 feels similar to other budget full-suspension bikes: clunky and unresponsive.

The bike is fast, and the suspension helps smooth out smaller bumps, but it quickly reaches its limits on rough terrain, and its performance is unrefined.

Pros

750W Motor

The 750W Bafang motor is responsive and capable, with 1000W peak power and 80Nm of torque. This motor easily propels the bike to over 20mph using the throttle and offers more than enough power for climbing hills.

Full Suspension

The XF900 benefits from its 110mm dual-crown suspension fork and rear suspension on light off-road terrain. This suspension is sufficient for smoothing out bumps on dirt and light gravel paths and small curbs and bumps when riding in urban environments.

However, the components lack the adjustability and performance required for proper MTB trails. Given that, we wouldn’t recommend using the XF900 for anything more than recreational riding.

Cons

Clunky

The XF900, with its full-suspension setup, looks like it would thrive off-road. The budget suspension handles mellow terrain well, but as I rode over larger rocks and roots, the suspension rebounded harshly, causing discomfort and making a lot of noise.

The suspension clunks and clacks as the wheels impact obstacles on the trail, and the fenders and chain add to the symphony of noises.

These sounds and vibrations don’t inspire confidence and leave you doubtful of the bike’s durability. Given that, I would limit this bike to light off-roading.

Battery Level Fluctuation

The battery level indicator fluctuates wildly based on motor output. For example, when engaging the throttle during the first range test, the battery level dipped from full charge (five bars) to two. After releasing the throttle, it leaped back to five.

Whether using the throttle or pedal assist, the battery indicator drops significantly, rebounding when the motor isn’t under load.

The bike discharges consistently and provides a low battery warning, functioning at reduced speeds for about 10 minutes after this warning.

However, the fluctuation makes it challenging to gauge the charge level, as you can only reliably read it when the motor isn’t engaged.

Overly Steep Head Tube Angle

The XF900’s ride quality was less enjoyable than I had hoped. The steep head tube angle pulls the rider over the front wheel, making for nervous, uncomfortable descending off-road.

Ghost Pedaling

The limited 7-speed Shimano Tourney drivetrain results in ghost pedaling at higher speeds. So, although this is a 28mph Class 3 e-bike, it’s challenging to reach the top speed.

What Does It Do Best?

The Cyrusher XF900’s unique styling will attract some buyers. The large 750W motor makes for an exciting ride, reaching over 20mph using the throttle alone.

The sizeable rear rack and 330lb payload capacity make it suitable for transporting cargo. Overall, it’s a decent choice for recreational riding on pavement and light trails.

Reasons to Look Elsewhere?

The XF900 is a large e-bike unsuitable for riders below 5’9″, so height is a limiting factor.

Riders who want true off-road performance should also look elsewhere, as the XF900’s noisy, rattling components, clunky suspension, and poor geometry limit its performance.

The bike’s size and weight (84lb) make it hard to lift or move, so ground-level storage is necessary. Finally, the wide tires and length create a wide turning radius, making it challenging to maneuver in smaller spaces.

Conclusion

Those looking for a budget full-suspension e-bike for recreational riding and light off-road fun may find value in the Cyrusher XF900, and its distinct look will turn heads out on the road or trail.

However, the performance is disappointing, especially the clunky suspension and budget Tourney drivetrain, making it hard to recommend.

Motor

The XF900 has a Bafang 750W motor capable of 1000W at peak output, enough power to push you up most hills with minimal effort. The throttle can also power you past 20mph, removing the need to pedal.

The bike is programmed to accelerate slowly, taking 10 seconds (pedal assist) or 12 seconds (throttle) to reach 20mph. This makes it feel more controlled and steady, which many users will enjoy.

The XF900 performed well in the longer, milder hill-climbing test, maintaining a high average speed. However, it struggled more with the shorter, steeper climb, coming in slightly slower than similar competition.

Cockpit and Control

The XF900 has a large centrally mounted backlit display. This monochrome, high-contrast display is easy to read and has additional features, such as a wattmeter. The 5-button control panel is easy to use and has dedicated buttons for the headlight and horn.

Battery

The bike is powered by a 48V 17Ah battery. I was surprised by the results of our range test, as the battery didn’t last as long as expected, given its size. This is likely due to the inefficiency of the full-suspension design and high weight. We covered just 21.5 miles and 922 feet of elevation at an average speed of 14.5mph.

The battery discharged consistently, offering the same amount of assistance until the low battery warning. Once the last bar begins to flash, the motor provides less power and continues to provide power for around ten minutes.

Charger, Battery Removal, Keys

The battery is externally mounted to the bike and recharges using a 54.6V 2A charger that will take at least nine hours to recharge fully.

Charging can be done on or off the bike via a port on the side. The battery is removed by inserting the key into the keyhole, turning, and pulling the battery upwards. We noted that the battery can get stuck, requiring extra force to release.

Drivetrain

The XF900 drivetrain includes a large 52t chainring with a double-sided guard and 7-speed, 14-28t cassette. The limited cassette results in ghost pedaling when approaching the max speed of 28mph. The shifter is a Shimano trigger shifter.

Brakes

The XF900 has Zoom dual-piston hydraulic brakes with 180mm rotors and a motor inhibitor switch. The braking power is good, with an average stopping distance of 19.5 feet, comparable to other bikes in this category.

The brakes are pleasant to use, but we have had issues with Zoom brakes, which need more frequent servicing to maintain performance.

Rims, Tires, and Fenders

The XF900 has a set of 26″ wheels wrapped in knobbly 4″ CHAOYANG tires. The tires have an aggressive mountain bike-style tread, which helps with traction over dirt, gravel, rocks, and roots.

The bike has plastic fenders that work well to block mud and debris. However, they bump and make noise as you ride.

Safety

The XF900 has brake inhibitors to aid with stopping. Additionally, it has an integrated 250-lumen headlight and an externally powered rear light.

Kickstand

The XF900 has the standard single-sided kickstand.

Contact Points

Grips

The grips are integrated with the throttle. They are made with hard plastic and aren’t very comfortable.

Saddle

The saddle has lots of padding and is larger than most. It didn’t inhibit pedaling and was comfortable throughout the 21-mile range test. The saddle also has a battery-operated light.

Pedals

The pedals are flat alloy pedals, similar to Wellgo flat pedals. They have small alloy studs and provide reasonable traction.

As for [the] quality of the parts, definitely we could ask for more, but I think the full combo is not too bad, although in my opinion [it’s] a little overpriced…

… it is an expensive electric bicycle… but it is also far from other models in terms of power and quality. 

You certainly get a lot: high power, larger-than-average battery, fast speeds, full-suspension, hydraulic disc brakes, included rack and fenders, etc. But it doesn’t come cheap.

… it’s pretty good! I mean you got the looks, it looks really nice, it looks badass, it’s long-lasting, it is powerful, [but] it’s not comfortable enough.

If you’re looking to do some exploring in the mountains on a dirt road, or ATV trail or just looking for a comfortable ride throughout the city on some paid trails, that’s where this bike is going to flourish.

The Cyrusher XF900 is a head-turner of an e-bike that is faster than your average fat tire e-bike…
