Description

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

It’s right for you if…

Youre looking for an e-MTB thats just as ready to shred as non-electric trail bikes. You want a powerful Bosch drive system thatll 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.
