Trek Rail 7 Gen 3

It features the same high-end trail tech as our analogue trail bikes, an upgraded fork, drivetrain, battery and more, plus a powerful Bosch drive system that's basically like having your own shuttle.

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 and a 625 Wh Removable Integrated Battery, a 160 mm RockShox Domain fork, the latest from Bosch with smart system Performance Line CX capable of speeds up to 32 km/h, including a Bluetooth® LED remote for easy connectivity and activity tracking through the eBike Flow app. A smooth-shifting 1x12 Shimano SLX/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.

Why you'll love it

The Alloy Rail Gen 3 features Bosch’s smart system with an LED remote that connects to the Bosch eBike Flow app for over-the-air system updates, customised motor tuning and more
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 to remove the battery without tools and lets you mount a water bottle cage
The Rail keeps your cockpit tidy by skipping a display, but smart system makes it easy to add one
The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
Made with the same hard-charging frame tech as our amazing trail bikes, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness and Active Braking Pivot (ABP)
