Go fast, go fun
Confidence at every turn
When you feel good, you ride good - which is why Karve RSX benefits from proportional sizing throughout the range, with specifically tuned dimensions, geometry, and front- and rear-centres designed to deliver balanced handling and uncompromised trail performance for every rider. By refining fit, weight distribution and ride dynamics for each frame size, Karve RSX stays planted, stable and predictable when trails get steep, rough and fast — delivering greater control, more confidence and a composed ride feel whether charging bike park laps, technical descents or full-gas enduro stages.
Avinox inside
Karve RSX has the power of Avinox's M2S motor system inside. Combining high peak power (up to 1300W) and torque (155Nm) with smooth, responsive delivery, the Avinox system gives you instant drive alongside high-fidelity control to ensure power arrives precisely when you need it, maintaining traction and composure on technical terrain. The internal 800Wh battery delivers the range for longer rides and repeat runs, while its compact, low-weight design preserves agile handling. Fully connected and highly customisable, it lets you fine-tune support to suit your riding – delivering consistent, dependable performance that works seamlessly with you on every trail.
Switch it up
Our Shape.It Link flip-chip lets you fine-tune the Karve RSX to match your riding style and terrain. Switch between the high and low settings to adjust geometry, slackening the head angle by 0.6 degrees and lowering the bottom bracket by 8mm in the low position. For maximum stability and a planted feel on steep, fast bike park laps and technical descents, run it low. Want a more responsive, efficient set-up for longer rides and big days in the hills? Keep it in the higher position for improved pedal clearance and all-day versatility.
