The Bike Cave Verdict
Ben's Take
The X9 Ultra is the performance halo of the range — a 60V dual-motor MTB peaking at 4000W and 240 Nm, with a claimed 43 mph and 0–31 in eight seconds. Unlike the touring-focused X-series, this one trades ultimate range (a still-healthy 120 mi claim) for pace and a genuine full-suspension, 26-inch big-wheel chassis, and the Samsung-celled pack and NFC lock are nice touches at $1,899. It's very fast on paper — well past Class 3 — so it's really an off-road/private-land machine, and I haven't put those numbers to the test on camera yet.
👍 What stands out
- 60V dual-motor with 4000W peak and 240 Nm
- Full-suspension 26×4.0 big-wheel MTB chassis
- Samsung-celled 60V battery with NFC lock
- Four colourways including Orange and Camo
👎 What to know
- Not yet reviewed on camera — figures are Tesway's claims
- 43 mph is well beyond Class 3 — off-road/private use
- Shorter range than the touring X5/X7 (120 mi claim)
- Fast, heavy and powerful — not a beginner's bike
