Sly RR 2025

Mondraker's Sly is a light-weight, aluminium framed, all-mountain electric mountain bike that ticks all the boxes.

Taking design inspiration from the incredible NEAT carbon framed e-mtb, the Sly shares the same travel, geometry and kinematics. This frame platform has been much loved for it's engaging ride, grip levels and agility.

Fitted to the Sly is the reliable Bosch SX performance motor, pushing out 55nm of torque with a peak power of 600W, paired with an integrated 400wh battery. An optional 250wh range extender is also available.

The RR spec ups the component level if you want some extra performance from your Sly. FOX suspension provides the 160mm Fox 36 29 Float Performance GRIP fork and a Fox Float X Performance EVOL shock.
SRAM Code Bronze Stealth 4 piston brakes with 200mm rotors keep things from getting out of hand on the steeps, and Mavic E-CrossTrail SL 30mm wheels offer the best balance of compliance / rigidity out there. ONOFF have you covered with a selection of components from the all new S6 range and include a carbon fibre bar, a stem, grips and the Pija seatpost with lengths varying from 140mm to 210mm depending on frame size
