Trek Rail 9 Electric Mountain Bike in Orange




The Rail 9 is the top-of-the-line alloy electric mountain bike with long-travel suspension. It features a suspension set-up and parts worthy of the gnarliest enduro runs, and the powerful new Bosch drive system will get you back up the mountain faster than you ever thought possible.

It's right for you if you're looking for a long-travel e-MTB that gives you a serious power boost without holding you back from hitting the techy terrain and big drops you love. You prefer to drop your upgrade budget on a plush suspension set-up and killer parts than on a frame.

You get A burly alloy frame that fully encases a 625 Wh battery, a super responsive RockShox ZEB fork with extra-beefy 38 mm stanchions and loads of adjustability, a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a Bosch Performance Line CX 250 W motor that assists up to 25 km/h, and a Kiox controller. A SRAM GX Eagle drive train with an extra-low 52-tooth climbing gear, downhill-rated 4-piston brakes for unflinching descents and Bontrager Line Comp 30 29er wheels with robust Bontrager SE5 Team Issue tyres that come completely tubeless-ready, including sealant.

The top-shelf alloy Rail features major upgrades to the suspension, drive train, dropper and more. If you’re looking for an e-MTB that’s spec’d like our best long-travel trail bikes and shreds just as hard, look no further.
