Trek Rail 7 Gen 2 Electric Mountain Bike
With its long-travel frame and burly components, the Trek Rail 7 Electric Mountain Bike delivers epic descending performance, all with the power needed to rally your way back to the top. The ABP suspension system mirrors of the brand’s much-lauded analogue offerings, providing 150mm of supple, traction-rich suspension, encouraging grip on loose, unpredictable terrain. This is paired with a high-capacity 625Wh battery and powerful Bosch Performance Line CX motor system to flow your way through undulating trails at a maximum assisted speed of 15.5 mph / 25 km/h, delivering the performance you need to crush singletrack all day long.
This model is loaded with tech, including an all-new RockShox Domain RC fork with a Motion Control damper and oversized eMTB-optimised crown for composure through rocks, roots and jumps. A 12-speed Shimano SLX drivetrain complements the motor, providing a wide range of usable gears, whilst the short, 165mm crank arms improve clearance to prevent pedal strikes. A TransX dropper quickly improves standover when the need arises, and strong, 29” Bontrager Line Comp 30 wheels ensure burly long-lasting performance.
