Mondraker Sly R
Mondraker Sly R

The Full Scoop on the Mondraker Sly R
The 2026 Mondraker Sly R redefines what a lightweight eMTB can be. Built around Mondraker's most advanced Stealth Alloy frame with seamless hydroformed tubing, the Sly R pairs the punchy Bosch Performance SX motor (55 Nm, 600W peak) with a compact 400Wh integrated battery for a ride that feels like a traditional trail bike with a hidden superpower.
The Updated Zero Suspension System delivers 150mm of plush rear travel, complemented by a RockShox Psylo Gold RC fork with 160mm up front. SRAM DB8 Stealth 4-piston brakes with 200mm rotors provide confident stopping power, while the wireless SRAM GX Eagle AXS T-Type 12-speed drivetrain keeps shifting crisp and cable-free. Over-the-air updates unlock eMTB+ mode with up to 400% pedal support.
Available in Optic White. One Sly fits all.
