Trek Rail 7 Deore/XT Gen 3 Electric Mountain Bike
With a burly alloy frame, 160mm and 150mm of travel front and rear respectively, and a powerful Bosch motor and battery system, the Trek Rail 7 Deore/XT Gen 3 Electric Mountain Bike is ready to hit the big stuff, and propels you back up too. More power and a bigger battery mean more fun on the trails (adding a pedalling assisted boost up to 15.5mph / 25kph), and the latest smart system with Bluetooth-connected LED remote maximises control and customisation of the system via the eBike Flow app. The Removable Integrated Battery (RIB) system is well hidden within the frame while being easy to remove for charging.
The frame itself incorporates Mino Link adjustable geometry, a stiff Straight Shot downtube and Active Braking Pivot (ABP), the latter keeping the rear suspension working as you brake to reduce chatter and unintentional skids.
A Shimano XT and Deore-mix 12-speed drivetrain brings effective, precise shifting and a wide gear range, while SRAM Code R powerful 4-piston hydraulic disc brakes stop you fast in all conditions. 29" wheels are fitted with nimble, grippy Bontrager XR4 Comp tyres for bump absorption and fast, confident cornering. A dropper post means you'll quickly be able to move the saddle out of the way for big drops and descents.
