TREK RAIL+ 8 GEN 5 FULL SUSPENSION eMTB BIKE 2025 POWER SURGE

eBikes by their very nature can require aftermarket updates and support. This cannot be supplied by All Terrain Cycles at distance; if required the work would have to be obtained from your local Brand Dealership, possibly at extra cost to yourself.

Your eBike will be delivered built, set up and updated in two boxes.

Minimum personal assembly is required.

The Rail+ 8 is an alloy enduro e-bike that packs in what you want most for big adventures. It comes equipped with a Bosch Performance CX drive system with full power for crushing laps and big climbs while its massive battery takes you the distance. 160 mm of front and rear travel make Rail+ super capable in the rough and rowdy, and adjustable geometry lets you customise it for how and where you ride.
