Motor | The motor on the rear wheel was co-developed with VISION for mountain biking:, - a torque of 42Nm to overcome any slope, - a 150x12mm hub to stand up to rough terrain, - and sealed bearings to withstand the weather, which can often be tough when mountain biking. What if you get a puncture? 8 Mm Allen key a needed to unscrew the wheel nuts. This tool is available in our 900 multi-purpose tool/bike multi-tool. | |

Battery | Our Rockrider mountain bike team has designed a battery that locks in place with a simple lever. Child's play! This locking system stops the battery getting shaken when you go adventuring on rough terrain. There is also a lock in case you want to stop your battery getting stolen. For example, if you park your bike in the street. |
