Trek Rail 9 7 Bike
Rail 9.7 is a long-travel carbon electric mountain bike that gets you to the fun stuff faster. It’s feels and rides just like our rowdiest trail bikes, and it’s built with the same trail-specific tech. The difference is that the powerful new Bosch drive system zips up climbs so you can spend less time grinding and more time getting rad.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
