It's right for you if...
You’re looking for a super capable long-travel e-MTB that’s built to conquer techy runs and big drops just as cleanly as analog trail bikes. You want the light weight and responsive ride of an OCLV Mountain Carbon frame.
The tech you get
A light and durable OCLV Mountain Carbon main frame with carbon stays that fully encases a 625Wh battery for sleek looks and protection on the trail, a 160mm RockShox Yari RC fork, 150mm of rear travel with a RockShox Deluxe RL shock, a powerful new Bosch Performance Line CX 250W motor that assists up to 20 mph, and a Purion controller. A 1x12 SRAM NX Eagle drivetrain, Bontrager Line dropper post, Shimano 4-piston brakes, and Bontrager Line Comp 30 29er wheels.
The final word
Rail 9.7 hits the sweet spot of carbon performance and amazing value. It’s spec'd with quality trail-specific parts and a powerful Bosch drive system so you can send it through the rough stuff and motor right back up for another run.
favorite_borderWhy you'll love it
- The new, better-than-ever Bosch motor is smaller, lighter, and more efficient. It feels more natural while you’re pedaling, and has less drag when you’re not
- Rail shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain—no shuttle or lift necessary
- 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
- It's equipped with an external charging port for easy charging on or off the bike
- 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)
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 farther 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.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.
