About this bike

The Rail+ 8 is an aluminium enduro e-bike with big power and tons of travel for wild, ride-anything adventures. It starts with an Alpha Platinum Aluminium frame paired with a RockShox Super Deluxe Select+ RT shock and ZEB Select fork (160 mm front/rear) for making quick work of chunky backcountry rock gardens. You get the smooth-shifting performance of a Shimano XT/SLX drivetrain, stop-on-a-dime control from SRAM DB 8 4-piston disc brakes, a Bontrager Line dropper post and tubeless-ready Bontrager Line TLR 30 wheels.
