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 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
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 150 mm of rear travel and a 625 Wh Removable Integrated Battery, an e-MTB optimised 160 mm RockShox 35 Gold RL fork, the latest from Bosch with smart system Performance Line CX capable of speeds up to 20 mph (25 km/h in Europe), including a Bluetooth® LED remote for easy connectivity and activity tracking through the eBike Flow app. Plus, a 1×12 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.
The final word
The Rail 5 625 is our best-value long-travel e-MTB. It’s equally as capable as our 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.
