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 new Bosch drive system will get you back up the mountain faster than you ever thought possible.

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.

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, 85 Nm) motor that assists up to 20 mph (25 km/h in Europe) and a Kiox controller.

Why you'll love it

1. RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
2. The full-colour Kiox display shows ride info, connects with your Bluetooth® enabled devices and has a built-in theft prevention feature
3. The Bosch motor gives you plenty of power for tackling steep climbs with the efficiency to keep exploring all day. Rider-friendly features, like Walk Assist and eMTB mode, help you make the most of every ride
4. Made with the same exclusive frame tech as Remedy and Slash, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness and Active Braking Pivot (ABP)
5. Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
