Trek Rail+ 8 Gen 5 2025 Electric Mountain 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.

Key Features

• The Rail+ delivers adventure with plenty of travel and power for getting after epic rides that take you peak to peak or chasing endless enduro laps


• The powerful Bosch Performance CX system goes full gas up steep climbs and keeps you cool for the descents


• You can tweak your geometry and suspension leverage rate for how you ride, and add in adjustable angle headset cups (sold separately) for even more adjustability


• Want even more boost? With the Bosch e-Bike Flow app, you can increase torque to 100 Nm and peak power up to 750W.


• The massive 800 Wh RIB 2.0 battery supports you for big miles and can be easily removed for travel or storage, and is compatible with PowerMore for even bigger rides
