The Rail 5 625Wh is an electric mountain bike built for ripping the big stuff. It features the same high-end trail tech as Trek's analogue trail bikes, plus a powerful Bosch drive system that's basically like having your own shuttle.

It's right for you if...

You’re looking for an e-MTB that’s just as ready to shred as non-electric trail bikes. You want a powerful Bosch drive system that’ll propel you up climbs so you can hit lap after lap.

The tech you get

A burly alloy frame with 150mm of rear travel and a 625Wh Removable Integrated Battery, an e-MTB optimised 160mm RockShox 35 Gold RL fork, the smart system Performance Line CX motor from Bosch which is capable of speeds up to 20mph (25km/h in Europe), including a Bluetooth LED remote for easy connectivity and activity tracking through the eBike Flow app. Plus, a 1x12 drive train with a wide gear range so you can always find the ideal cadence for the motor, a dropper post, powerful 4-piston brakes for more downhill confidence and 29er wheels with nimble yet grippy 2.6" tyres.

Why you'll love it

• The Rail Gen 3 is built for big adventures, with Bosch's smart system that packs in all the power you need, and a Bluetooth-connected LED remote that's sleek and intuitive
• 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 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)
• The bigger battery means you can adventure for longer between charges

Removable Integrated Battery

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.

Bosch Performance Line CX motor

The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Bosch LED Remote

The Bosch smart system LED remote lets you easily change assist modes, activate walk mode or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.

Bosch Smart System

The Bosch smart system gives you an eMTB that's more connected than ever. The LED remote connects with Bosch eBike Flow app so you can get ride stats, adjust settings and perform system updates. Plus, Bluetooth connectivity makes it easy to add a display if you want to make it easier to see your ride data.

Bosch eBike Flow app

The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.

Active Braking Pivot

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.

Shimano Deore

Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff and the fun. With smooth riding, improved chain stability and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.

The final word

The Rail 5 625Wh is Trek's best-value long-travel e-MTB. It's equally as capable as their regular long-travel trail bikes, it just gets you back to the top in a flash. Plus, the bigger battery means more time on the trail.
