Description

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 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

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.
