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 150mm of rear travel that fully encases a 625 Wh battery, a 160 mm RockShox Domain RC fork, a powerful Bosch Performance Line CX (250 W, 85 Nm) motor that assists up to 20 mph (25 km/h in Europe) and a Purion controller. A smooth-shifting 1x12 Shimano Deore/XT drivetrain, 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 drivetrain, fork and wheels. But the biggest deal is that it comes with a long-range Bosch battery – which means more runs and more fun.

favorite_borderWhy you'll love it
- The Bosch motor gives you plenty of power for tackling steep climbs with the efficiency to keep exploring all day
- Rail shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain – no shuttle or lift necessary
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
- 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
Features
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.
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.
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.

Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.

Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure – no more error codes from mis-aligned sensors.
Bosch Purion Display
Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.
Complete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

ABP
Our patented Active Braking Pivot allows your suspension to work freely whether you’re on the brakes or off. It’s smooth, controlled suspension that’s at its best all the time.
