The Cube Reaction Hybrid Pro 400 Electric Mountain Bike is built to take the road less travelled with advanced e-bike technology and design to take some of the hard work out of riding on the trails. Cube’s High Performance Aluminium Frame carries the Bosch PowerTube 400 Battery which is seamlessly integrated for a balanced ride that feels as good as it looks. Paired with a Gen 4 Bosch Performance Drive Unit (250 Watt) for a smooth ride that climbs with ease so that you can enjoy the best parts of mountain biking. The SR Suntour XCM34 Coil Fork with 100mm travel and lockout allows you to tackle the trails with confidence and capability.

The Reaction Hybrid Pro is equipped with a high-quality 1x12 speed SRAM SX Eagle drivetrain which is suitable given the support of the Bosch drive unit, the 1x setup is clean, efficient and minimises any hassle while you're riding. While the Shimano MT200 Hydraulic Disc Brakes with 180mm rotors will give you reliable stopping power and control in all conditions and surfaces. Control is further improved by the 29 inch Schwalbe Smart Sam Tyres which are paired with Cube's own EX30 tubeless ready rims. If you like everything you see here but want a better battery, simply step up to the Cube Reaction Hybrid Pro 500 which has almost the same spec, just the with PowerTube 500 instead of the 400.
