The Cube Reaction Hybrid HPA Pro 400 combines the day-to-day practicality of a performance hardtail with the latest Bosh Drive technology and a hand-picked selection of quality components. The result is a highly capable e-Bike that is as comfortable out on the trails as it is on a daily commute.

The aluminium superlite frame has been updated for 2017 to meet the requirements of Bosch’s latest drive system and to offer the maximum possible versatility. The frame includes internal cable routing to protect gear and brake cables and to keep the bike looking tidy, and has room to mount mudguards to help keep you clean when you cycle to work. Cube have perfectly combined an optimal drive position with agile ride geometry and a carefully sited battery to create a bike that is both efficient and incredibly fun to ride. With seven different frame sizes it’s easy to find your perfect fit, the 14, 16 and 18inch bikes come with 27.5inch wheels and the 17, 19, 21, and 23inch bikes come with 29inch wheels to perfectly match the frame size with the wheel size. 

The highlight of the Reaction Hybrid HPA Pro 400 is the new Bosch CX Drive system. With up to 75Nm power assist the motor packs plenty of punch - perfect for long, technical climbs, and the high capacity 400Wh battery will keep you going all day long. Combined with the Bosch Purion display, the CX Drive System is easy to use and offers exceptional performance. 

If you want an e-Bike that can blast around the trails on the weekend and get you to work throughout the week, the Cube Reaction Hybrid HPA Pro 400 is the perfect bike for you.

About Cube

Cube is a brand that has been experiencing continuous growth since their inception in 1993. In fact, expansion work at their HQ and production facility in Waldershof, Germany has been ongoing constantly for over 15 years. Cube even purchased their own construction company to reduce the costs associated with a 6-fold increase in size, German efficiency at its finest!

Cube’s success can be attributed to a mix of innovation, premium quality materials, state of the art technology and a Teutonic obsession with product testing. They take a highly technical approach to building bicycles, with each model being designed and tuned using CAD software before being transferred into aluminium, carbon fibre or titanium for extensive ride testing.
