Why is it so light?The Frame MaterialsHeat treated aluminum and high strength glass fibre reinforced engineering polymer constitute the majority of the frame. The Twin Chain The twin chain gearing system specifically uses small drive axles, often one of the heaviest parts of a traditional bicycle. Pedal cadence remains the same as a normal bicycle. The WheelsEach weighs only 350g and this includes the pneumatic tyres which give such a smooth and comfortable ride. The BrakesDesigned specifically for the A-bike, the semi circular band brakes fit the wheel perfectly providing a lightweight and robust alternative to traditional shoe brakes.
