2026 TREK Rail+ 8 Gen5

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+ 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.

You want a bike that maximises the fun and is up for gnarly rides that get you off the grid or just hammering in an extra lap or two. You need the capability of an enduro bike for pointing it down the rough and rowdy, and love the feeling of full assist taking the sweat out of the climb back to the top for more

An Alpha Platinum Aluminium frame with a Bosch Performance CX system (85 Nm, 250 W) and 800 Wh Removable Integrated Battery 2.0. A 160 mm RockShox ZEB Select fork with DebonAir spring, Motion Control damper and lockout and a RockShox Deluxe Select+ RT shock. All topped off with a Shimano XT and SLX blended 12-speed drivetrain, dropper post, Bontrager Line Comp 30 Tubeless Ready wheels and 4-piston Shimano hydraulic disc brakes.

The Rail + 8 is an enduro e-MTB dialled for big adventures. It packs in capable, adjustable geometry, a massive battery and a powerful motor to get you wherever you want to go. An upgraded drivetrain balances price and performance for a ride that's ready for anything.

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
