Rail + 8 Jan 5

Trek Rail+ 8: the aluminum e-enduro ready for anything

The Trek Rail+ 8 is an aluminum enduro e-MTB designed for riders who want to push hard in any condition. The Alpha Platinum Aluminum frame houses RockShox suspension with 160mm of front and rear travel: the Lyrik Select fork and Super Deluxe+ shock work together to let you float over rock gardens, roots, and bike-park rock sections.

The heart of the Rail+ 8 is the Bosch Performance Line CX Smart System motor: 85Nm of torque as standard, upgradeable up to 100Nm and 750W via the Bosch eBike Flow app. The eMTB mode with Extended Boost automatically meters assistance based on the terrain, giving you traction, control, and power when you really need it.

The SRAM Eagle 12-speed drivetrain ensures precise shifting even under load, while the Shimano M620 4-piston brakes deliver consistent stopping power on the longest and steepest descents. The Bontrager Line dropper post and Bontrager Line TLR 30 wheels round out a build made for aggressive electric enduro riding.

If you’re looking for a powerful, reliable, and fun enduro e-bike , the Trek Rail+ 8 is your ideal companion for technical trails, alpine rides, and epic backcountry adventures.
