No trail is too long, no mountain too high for the Reaction Hybrid HPA Race. Whether it's a ride with the family or a flat out blast on your favourite trails with your riding buddies, you'll discover a new appreciation for mountain biking with this bike. Combining human power with the Bosch CX motor - delivered to the rear wheel via an aluminium Superlite frame and a Shimano XT 11-speed transmission - results in a riding experience in a class of its own. Available as a 29er or with 27.5in wheels for the perfect fit, whatever your height.

Frame: The double butted aluminium Superlite frame was developed specifically to match the requirements of the new Bosch system, and we've upgraded it for 2017 to include clean-looking, low-maintenance internal cable routing. The frame is extremely stiff despite being very light - and that means fantastic drivetrain efficiency and superb steering precision. That's a good start, but it's really the combination of our in-house Agile Ride Geometry (ARG) and the optimal positioning of the Bosch system (ODP) that transforms the Reaction Hybrid Race into a fleet-footed, fast-accelerating trail rocket with the kind of handling that most e-bikes can only dream of.

Features: Bosch's new CX drive, with up to 75Nm of torque, sets the standards for MTB drive systems. It gives you the ultimate motor-driven support for longer rides, while taking you to impressive heights in exchance for relatively little effort. The standard battery is an impressive 500Wh for the best possible range. Shimano's 11-speed XT transmission - with XT ShadowPlus rear derailleur - has an exceptionally wide gear range, making it the perfect setup for an e-bike. It's the same story with the brakes, Shimano's BR-M315 hydraulic discs are powerful and providing reliable stopping in all weathers via 180mm rotors at both front and rear. Light, stiff wheels are built around Shimano XT hubs. The Rock Shox Recon Silver suspension fork features 100mm of smooth, controllable travel, stiff 32mm stanchions and adjustable rebound damping with remote lockout - perfect for clearing the path ahead and embarking on new trail adventures.
