Trek Rail+ 8 Gen 5 E-Mountain Bike In Dark Star

Season:2025

Brand:Trek

Code:48470BLK

The Rail+ 8 is an alloy enduro e-bike that packs in what you want most for big adventures.

It comes equipped with a Bosch Performance CX drive system with full power for crushing laps and big climbs while its massive battery takes you the distance. 160 mm of front and rear travel make Rail+ super capable in the rough and rowdy, and adjustable geometry lets you customise it for how and where you ride.

It's right for you if...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

The tech you get - 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 Domain RC 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 - 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.

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
  • The massive 800 Wh RIB 2.0 battery supports you for big miles and can be easily removed for travel or storage
  • It's compatible with the Bosch PowerMore booster battery for going even further on epic adventures
