Trek Rail 9 GX AXS 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 9 GX AXS 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. 

This is Trek's top-of-the-line long-travel alloy electric mountain bike and 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. 

SRAM's GX Eagle AXS wireless electric drivetrain brings precise and instant shifting, and the extra low 52-tooth cog is perfect for getting you up the steepest climbs. SRAM Code R powerful 4-piston hydraulic disc brakes stop you fast in all conditions. Bontrager Line Comp 30 29er wheels fitted with robust Bontrager SE5 Team Issue are a great pairing, made to handle the forces of an electric off-road machine. A dropper post means you'll quickly be able to move the saddle out of the way for big drops and descents.
