Mondraker Sly R

Mondraker calls the frame technology Stealth Alloy EVO, and the engineering shows in ways you don't normally see on aluminum. The welds between frame tubes are finished so seamlessly they're nearly invisible — you'd have to knock on the frame to be sure it isn't carbon. Beyond the aesthetics, the frame carries internal cable routing through the headtube HHG (Hidden Cable Guide), a custom rubber chainstay protector, an integrated chain guide, and UDH (Universal Derailleur Hanger) compatibility with Sram's T-Type drivetrain. The geometry is pure Forward Geometry: a 64.5° head tube angle across all sizes, a steep 74° seat tube, a 30mm stem, and reach figures ranging from 440mm on the S to 520mm on the XL. It's long, low, and slack — designed around stability at trail speeds, not around making numbers look approachable on paper.

The motor is the Bosch Performance SX: 55Nm of torque, 600W peak power. This is the key distinction between the Sly and Mondraker's heavier enduro models — the Crafty, Level, and Scree all run the full-power Bosch CX. The SX is physically smaller and lighter, and the power delivery is tuned to feel like a natural extension of your own effort. On flowy trail sections and punchy climbs, you feel the motor responding rather than leading. Via the Bosch eBike Flow app, an over-the-air software update unlocks the eMTB+ riding mode and increases pedalling support…
