You’re looking for a long-travel carbon e-MTB with high-performance parts. You crave the responsiveness of carbon, the plush feel of high-end suspension, and would rather get all the good stuff now than have to upgrade down the line.
An OCLV Mountain Carbon frame that fully encases a 625 Wh battery, a super responsive RockShox ZEB Select+ fork with extra-burly 38 mm stanchions and loads of adjustability, a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a Bosch Performance Line CX 250 W motor that assists up to 20 mph (25 km/h in Europe) and a Kiox controller. A smooth-shifting Shimano XT drive train, 4-piston brakes for confident descents and Bontrager Line Comp 30 29er wheels with robust SE5 Team Issue tyres that come completely tubeless-ready, including sealant.
This bike features across-the-board upgrades that make it a serious ripper – especially the suspension package. It’s built for hammering gnarly descents, then flying right back up again thanks to the powerful Bosch drive system.
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.
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.
Trek’s mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek’s advanced engineering, and a higher standard of testing.
With the all-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most refined shock on the market, with an updated air spring and an exclusive Thru Shaft damper that gives you tenacious grip, plush control and the support you need for ripping rough descents all day.
