It's right for you if...

You’re looking for a trail-specific e-MTB that’s designed to tackle the same tough terrain as regular trail bikes. You already know just how amazing e-MTBs are on the mountain, and want to invest in better components.

The tech you get

A burly alloy frame with 150 mm of rear travel that fully encases a 625 Wh battery, a 160 mm RockShox Yari RC fork, a powerful new Bosch Performance Line CX 250 W motor that assists up to 32 km/h and a Purion controller. A smooth-shifting 1x12 Shimano SLX/XT drive train, dropper post, powerful Shimano 4-piston brakes for confident descents and Bontrager Line Comp 30 29er wheels that are already completely tubeless-ready, including sealant.

The final word

The Rail 7 features loads of upgraded parts, including the drive train, fork and wheels. But the biggest deal is that it comes with the longest-range Bosch battery you can get. That means more runs and more fun.

favorite_borderWhy you'll love it

  1. 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
  2. Rail shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain – no shuttle or lift necessary
  3. The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
  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


Features

New Bosch Performance Line CX

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

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.
