Mondraker SLY RR — Lightweight Power, Full-Trail Control

The Mondraker SLY RR redefines what a lightweight e-mountain bike can be. Built around Mondraker’s Stealth Evo aluminum frame and powered by the ultra-compact Bosch Performance Line SX motor, the SLY RR delivers natural trail feel with just the right amount of assist. It’s the perfect choice for riders who want the handling of a modern trail bike with the efficiency and range of a next-generation e-MTB.

With 150mm of rear travel paired to a 160mm Fox 36 fork, the SLY RR is designed to charge technical descents while staying nimble and efficient on climbs. Mondraker’s Forward Geometry keeps the bike planted and confident at speed, while the lightweight Bosch SX system maintains a responsive, analog-like ride feel that disappears beneath you once you’re moving

Bosch Performance Line SX — Lightweight Assist That Feels Natural

At the heart of the Mondraker SLY RR is the Bosch Performance Line SX motor, a game-changer for lightweight e-bikes. Weighing just 4.4 lb (2.0 kg), the SX motor delivers up to 600 watts of peak power and 55 Nm of torque, perfectly tuned for trail riding rather than overpowering it.

The compact SX motor provides smooth, quiet assistance up to 20 mph, enhancing your pedaling without masking trail feedback. Paired with the Bosch Compact PowerTube 400Wh battery, the system strikes an ideal balance between range, weight, and agility—making the SLY RR one of the most capable lightweight e-MTBs available.

Built for Riders Who Want Less Weight and More Trail Feel

Weighing in at approximately 45.6 lb, the Mondraker SLY RR sits firmly in the lightweight e-MTB category. Compared to traditional full-power e-bikes, it’s easier to maneuver, quicker to accelerate, and more engaging on tight, technical trails.

High-end components—including SRAM GX Eagle AXS T-Type wireless shifting, SRAM Code 4-piston brakes, and Maxxis Minion tires—round out a build that’s ready for aggressive trail and all-mountain riding right out of the box.
