Plus, a new smart e-MTB mode that manages the assist level automatically, a Shimano Deore 10-speed drivetrain, a saddle designed for women, hydraulic disc brakes, and a RockShox Judy Silver TK fork with 100mm of travel.

The final word

A fully capable women's e-MTB with durable parts and the best Bosch mountain bike electric assist system available. The drivetrain, suspension, and components deliver solid all-around performance, so you can commute to the trailhead and then spend all day riding.

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 Trek retailer.
