It's right for you if...
You want more than just the added confidence of electric-assist. You also want the performance of quality mountain bike parts, and you're willing spend some extra cash to get them because you know they make a difference on the trail.
The tech you get
A durable Alpha Platinum Aluminium frame with 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 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. It can make the steep climbs, hard-to-find trails and epic rides of your dreams a reality.
favorite_borderWhy you'll love it
- 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
- It actually makes climbs as enjoyable as descents
- 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
- The long-life battery is secured within the downtube and is easily removed for charging
Batteries integrated into the downtube provide a sleek look and keep weight low for a stable ride. They are easily removable without additional tools for charging or safe keeping.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone else's.
This unique protection shield made of lightweight but robust aluminium protects the motor against stones.
Going for a long ride? Rack mounts make carrying accessories a breeze.
