The Rail 9 is our 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 Bosch drive system will get you back up the mountain faster than you ever thought possible. It comes decked out with a wireless SRAM AXS drivetrain for reliable shifting and an ultra-tidy cockpit.

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 cash on a plush suspension set-up with killer wireless SRAM AXS drivetrain than on a frame.

The tech you get

A burly alloy frame with a 625 Wh Removable Integrated Battery, a super-responsive RockShox ZEB fork with extra-beefy 38 mm stanchions and loads of adjustability, a RockShox Super Deluxe Select+ shock, the latest from Bosch with smart system Performance Line CX capable of speeds up to 20 mph (25 km/h in Europe), including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app. A SRAM GX Eagle drivetrain with an extra-low 52-tooth climbing gear, and Bontrager Line Comp 30 29er wheels with robust Bontrager SE5 Team Issue tyres that come completely tubeless-ready, including sealant.

The final word

Our top-shelf alloy Rail features major upgrades to the suspension, drivetrain, 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.
