The Mondraker Sly RR Bike makes a confident argument for aluminum in the light e-MTB segment. Built on a hydroformed 6061 Alloy Stealth EVO frame with Mondraker's signature Forward Geometry, the Sly RR delivers legitimate trail performance — slack enough to inspire confidence on technical descents, efficient enough to climb all day — without the carbon-fiber pricing that typically accompanies this level of suspension and component spec. At $7,999, this is a serious electric mountain bike positioned for riders who want real capability, not just assisted pedaling.

The motor at the heart of the Sly RR is the Bosch Performance Line SX, a compact, trail-optimized unit producing 55Nm of torque. It's the lightest Bosch motor available for trail riding, and it shows in how the bike handles: the assistance feels natural and intuitive rather than intrusive. Power delivery responds to your input and cadence rather than overwhelming it, making the Sly RR feel more like a very capable mountain bike than a machine that happens to have a motor. The Bosch Compact Powertube 400Wh battery is integrated into the downtube, and the system is compatible with Bosch's 250Wh bottle-cage-mounted range extender for riders who want to push deeper into the backcountry without watching the gauge drop.
Geometry is where Mondraker has always stood apart. Forward Geometry — the brand's philosophy of designing around reach and rider position — results in a 64.5° head angle across all sizes, slack enough to handle fast, technical terrain without requiring aggressive counter-input, paired with a 74° seat tube angle that keeps you in a powerful pedaling position on extended climbs. Rear suspension uses Mondraker's Updated Zero Suspension System, a two-link co-rotating design with 150mm of travel, driven by a Fox Float X Performance EVOL shock. Up front, a Fox 36 Float Performance GRIP fork handles 160mm of travel with a three-position compression adjustment for tuning to the trail. Chainstays hold at…
