The Cyrusher XF900 Pro is a full suspension fat tire e-bike with a motorcycle stance: a dual crown air fork with hydraulic lockout, an oil and spring rear shock on a linkage frame, 26 x 4 Chaoyang tires and a 48V 750W rear hub with 85 N.m. Cyrusher rates it at 28 MPH and up to 50 miles from the 48V 13Ah battery.
HD-E500 hydraulic disc brakes on 180mm rotors stop it, a Shimano 7 speed covers the climbs and the rear light carries running, brake and turn signal functions. It weighs 71.2 lb, carries 350 lb and fits riders from 5'7" to 6'6". Want a step through? That is the Kommoda Pro.
Built to be lived with
A 26 x 4 linkage full suspension frame, an XR-3 dual crown air fork with hydraulic lockout, a 210mm oil and spring rear shock, Shimano 7 speed gearing, 180mm hydraulic discs with sintered pads and Chaoyang 26 x 4 tires on 36 hole rims.
A smart display with turn signal indicators, a headlight, a rear light with brake and turn signals, a kickstand and a memory foam saddle come on the bike. Cyrusher covers the frame for two years, the battery and parts for one.
The XR-3 dual crown fork has adjustment and a hydraulic lockout, so it soaks up a rutted trail and firms up for the ride home on pavement. At the back a 210mm oil and spring shock on the redesigned linkage frame takes the edge off broken road and gravel.
Chaoyang 26 x 4 tires put a wide footprint on the ground. Cyrusher calls it mixed surface riding: city streets, gravel roads and dirt paths, not downhill.

The rear light runs as a running light, a brake light and left and right turn signals, with the indicators on the handlebar display. Cyrusher added it for riders who share the road with cars.
The 48V 750W rear hub puts out 85 N.m through a 22A controller and a Shimano 7 speed. A cadence sensor and a throttle run the assist. Cyrusher sells it as Class 2 or 3, so where you ride at 28 MPH depends on local rules.

Cyrusher quotes up to 50 miles from the 48V 13Ah, 624Wh battery and calls that a best case figure at low assist on easy ground. Rider weight, hills, wind and throttle use all bring it down. It is the smallest battery in the Cyrusher fat bike line, so plan rides around that.
Cyrusher lists the XF900 Pro as Class 2 or 3, with 28 MPH in pedal assist. In most US states that is legal on roads and many bike lanes, but paths and trails set their own limits. Check your state and local rules.
One size, step over. Cyrusher lists riders from 5'7" to 6'6". The standover is 29.1 inches, the saddle sets from 34.8 to 44.3 inches, reach is 26.6 inches, the wheelbase is 48.8 inches and the bike is 77.6 inches long. Shorter riders should look at the step through Kommoda Pro.
No. Cyrusher says the Pro keeps the XF900 look but has an updated linkage frame, the dual crown lockout fork, the oil and spring rear shock, hydraulic brakes and the rear turn signal lighting. Reviews of the original XF900 online describe the earlier bike.
Mostly. You fit the front wheel, handlebar, pedals and saddle with the tools in the box, then check every bolt and the tire pressure before the first ride. Cyrusher posts an assembly video.
Cyrusher covers the frame for two years and the battery and other parts for one year against manufacturing defects, for the original owner, by replacing the defective part. Crashes, water damage, modifications and normal wear are excluded. We are an authorized dealer, so it applies.
