Wheel Aluminium double walled and reinforced, 13G spokes with Kenda Puncture resistant tyres, 700C Best features We wanted to produce a lightweight but powerful electric bike, that's comfortable to ride. To achieve all of that some very special components came together to create Roller: Roller's motor is a high torque Aikema producing over 50NM and is virtually silent with some very nicely engineered internal gearing that produces an amazing amount of power from such a small unit weighing just 2.1Kgs. Roller's responsiveness is a result of specially tweaked software configured within a sinusoidal controller. The front LED light is powered from the main battery. Roller's rear light is self-powered, just in case the main battery gets all used up during the day. Roller has a standard LED display to control the bike or an optional LCD Display, fully integrated with bike power functions and which has 5 levels of assistance, odometer and speed. We've selected wide, comfortable handlebars which have our snazzy, quick adjust mechanism and are swept to provide a wide range of arm and wrist positions, quickly. Roller's lightweight RST aluminium forks use a single shock absorber with 35mm travel and weigh just 1.4Kgs.
