Trek Rail 9.8 GX AXS Electric Mountain Bike 2022

The Rail 9.8 GX AXS Electric Mountain Bike by Trek is at home on the trails and pairs a solid but lightweight carbon shell with high-performance power-assisted technology for that extra kick up more challenging climbs. Steep technical hills are handled easily with the 85Nm of torque provided by the Bosch Performance Line CX motor. At the same time, the various power modes allow instant control via the onboard Bosch Kiox computer.

The battery offers an incredible 750Wh that will last on long adventure days, and it sits within the downtube for a neat integrated look. The battery can be removed easily using a unique key for charging and provides an additional level of security. A small but mighty Mino Link features in the frame's seatstay to allow the option to change the geometry by simply switching the link from a steeper seat tube angle to a slacker one to suit different trails.

RockShox provides the suspension, with 160mm from the Zeb Select+ on the front and 150mm of plush Super Deluxe Ultimate RT3 on the rear, making this bike ready to conquer all-mountain riding with force-absorbing capability.

SRAM's Eagle 12-speed groupset extends the level of support with a large 10-52 cassette ratio that is operated wirelessly. With an app, Bluetooth connectivity is easily achieved and links to the cockpit computer for on-demand control. SRAM Avid Code R supplies hydraulic braking with a 4-piston caliper offering a natural and reliable feel.
