Should you buy one?
Buy the XF900 if about 90% of your riding is dirt and gravel. That’s the rider I said it’s for (7:23 to 7:52). It has rear suspension plus a big dirt-bike-style air fork you can inflate and deflate (4:29 to 4:46), 4 in tires (6:36 to 6:40), and a range I called pretty impressive for its size (5:20 to 5:28).
Skip it if you ride mostly on the road. I said plainly it’s not the one for you (7:40 to 7:52). Also skip it if you want strong acceleration. The 750W motor felt lackluster on a bike this heavy (4:46 to 4:57, 5:30 to 6:11).
The deciding factor: suspension versus power. You get a lot of suspension, but the motor doesn’t feel like the dirt bike the bike looks like (5:47 to 6:01).
I rode this bike for a three-bike comparison, not a full solo review. You can read the Sinch ST vs Cyrusher XF900 vs Wallke F1 comparison for the full head-to-head.
See the current XF900 Pro at Cyrusher ($1,199, down from $1,399, on cyrusher.com as of Oct 23, 2026. That’s the newer Pro version, not the bike I rode.)

Source note: times in parentheses are from my comparison video. Everything marked (Cyrusher) is from Cyrusher’s XF900 spec listings for the original XF900 (its XF900 vs Aventure comparison post and its spec page). Cyrusher’s height range varies by page, so I’ve left it out. The XF900 Pro sold today is a different spec: 624Wh battery, 71.2 lb, 350 lb max load and hydraulic brakes, per cyrusher.com on Oct 23, 2026.
What I didn’t test
I didn’t run a range test, a top-speed test, or a braking test. I didn’t weigh the bike either. The 50 to 62 mile range and the 74 lb weight are Cyrusher’s numbers. My range comment (5:20 to 5:28) is an impression, not a measured ride.
Who it’s for
- Riders on dirt and gravel trails most of the time (7:23 to 7:52).
- Riders who want rear suspension and a fork they can tune with air (4:29 to 4:46).
- Riders who want lights, a horn, fenders and a rack included (4:57 to 6:30).
Who should look elsewhere
- Road commuters (7:40 to 7:52).
- Riders who want punch. A smaller 500W bike felt stronger to me (9:10 to 9:20).
- Anyone who needs to lift the bike often (5:14 to 5:20).

Rival specs are from the brands, as listed on my review pages for those bikes.
All four are full-suspension fat-tire bikes. The XF900 has the smallest battery of the four that list capacity, and the Obsidian and Adventurer list more torque.
