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 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.

Our 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.
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- The full-colour Kiox controller displays ride info, connects with your Bluetooth® enabled devices and has a built-in theft prevention feature
- The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you're pedalling, and has less drag when you're not
- 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)
- 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

New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It's also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.

Custom eMTB Lite mode
Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.

Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It's the most convenient way to remove your battery for transport, security or just easier charging.

Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Knock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
