TREK RAIL+ 8 GEN 5

Rail+ 8 is an aluminum enduro e-bike with big power and tons of travel for wild, ride-anything adventures. It starts with an Alpha Platinum Aluminum frame paired with a RockShox Super Deluxe+ shock and ZEB Select fork (160mm 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.

It's right for you if...
You want a bike that maximizes 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.

The tech you get
An Alpha Platinum Aluminum frame with a Bosch Performance CX system (85Nm, 250W), and 800Wh Removable Integrated Battery 2.0. A 160mm 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 final word
Rail + 8 is an enduro e-MTB dialed 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.
