Trek Rail 9.9 Electric Mountain Bike 2021
Explore off the beaten track with the Trek Rail 9.9 Electric Mountain Bike, crafted from lightweight OCLV Mountain Carbon and kitted out with all the goods for optimal off-road adventuring. This is a top-end e-MTB hungry for trails, complete with RockShox's ZEB Ultimate fork with chunky 38mm stanchions, and loaded with 160mm of travel to tackle all-mountain terrain. The Bosch Performance CX motor provides up to 250W of assistance to aid tough climbs, and ticks up to 25 km/h should speed be needed.
This motor is compact, efficient and light to encourage a natural sensation when pedalling and minimal drag when not, and the Bosch PowerTube 625 battery is entirely charged in under 5 hours with a standard charger should you wish to plan for a ride in advance. Trek's Removable Integrated Battery system is intuitive for easy, tool-free removal when a charge is needed, and well hidden within the frame during use - leaving space for a bottle cage to be mounted too. Should angles and geometry need refining, the Mino Link enables these to be fine tuned to to best fit rider preference.
SRAM X01 12-speed components make quiet, clean shifting a cinch, with a multitude of gearing options to suit flowing undulations and steep gradients, and they're tough enough to tackle no-holds-barred trail use. SRAM Code RSC hydraulic disc brakes are responsive for rapid stopping so descents can be handled with improved confidence, making this bike good clean fun on every ride. Seriously good components elevate this bike to new, off-road conquering heights.
