Trek Rail 9 Gen 3 Full Suspension Electric Mountain Bike 2023

The Rail 9 is Trek's 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 Bosch drive system will get you back up the mountain faster than you ever thought possible. It comes decked out with a wireless SRAM AXS drivetrain for reliable shifting and an ultra-tidy cockpit.

It's right for you if...

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.

The tech you get

A burly alloy frame with a 625 Wh Removable Integrated 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, the latest from Bosch with smart system Performance Line CX capable of speeds up to 20 mph (25 km/h in Europe), including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app. A SRAM GX Eagle drivetrain with an extra-low 52-tooth climbing gear, and Bontrager Line Comp 30 29er wheels with robust Bontrager SE5 Team Issue tyres that come completely tubeless-ready, including sealant.

Why you'll love it

• 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 Bosch motor gives you plenty of power for tackling steep climbs with the efficiency to keep exploring all day
• Bosch's new smart system gives you all the same power and responsiveness with a new Bluetooth-connected LED remote and eBike Flow app that puts even more control and customisation at your fingertips
• 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 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)

The final word

Trek's top-shelf alloy Rail features major upgrades to the suspension, drivetrain, 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.
