Description

The all-new Rail+ 8 is a super capable alloy Enduro e-bike for big adventures. Kitted out with a Bosch Performance Line CX system and  800 Wh Removable Integrated Battery 2.0, you will be powered up steep climbs, kept cool for the descents and can explore for longer. It is engineered with an Alpha Platinum Aluminium frame and RockShox ZEB Select fork with a DebonAir spring that delivers 160mm of front and rear travel, making the Rail+ 8 a powerhouse in the rough and rowdy. The mixed wheel set-up means you've got the best of both worlds: a 29" front wheel for riding stable and steady over technical singletracks and a 27.5" rear wheel to ensure you maintain nimble agility in turns and corners.

Experience the smooth-sailing performance from the Shimano XT drivetrain and efficient stopping power with SRAM's DB 8 4-piston brakes. You can tweak your geometry and suspension leverage rate, allowing you to customise for how and where you ride. The Rail+ 8 Gen 5 from Trek is the ideal choice if you are looking for an enduro e-MTB that is up for hammering down gnarly rides and never backs out.
