It's right for you if...

You prefer the fit and feel of a bike made for women and want more than just the added confidence of electric-assist. You also want performance mountain bike parts, and you're willing spend some extra cash to get them because you know that they make a difference on the trail.

The tech you get

A durable Alpha Platinum Aluminium frame with a lower standover height for added confidence, a Bosch Performance CX 250-watt motor that assists up to 20 mph, an ergonomic Bosch Purion controller and an integrated, long-range 500 wH battery that's secure while you're riding, but easy to remove for charging. Plus, a Shimano SLX/XT 1x11 drivetrain, a saddle designed for women, a RockShox Recon RL 100 mm suspension fork and a dropper post.

The final word

This is where performance electric-assist and performance mountain bike parts meet. Take it up the steep climbs that you've only seen in pictures and dreams, then descend down the other side like a true mountain biker.

favorite_borderWhy you'll love it

  1. It rides like a mountain bike because it is one: it has the same frame and suspension tech that we've refined in our decades-long trail heritage
  2. It actually makes climbs as enjoyable as descents
  3. It's more than a mountain bike: pedal-assist means you can ride to the trail-head, then hit the single-track without having to shuttle your bike there by car
  4.  The unique women's frame has a lower standover height for extra confidence
