Carbon fibre
E-bikes that use carbon fiber are a common choice among amateur and professional cyclists. Previously, it was mainly road e-bikes, but today you can enjoy the benefits of carbon on almost any type of e-bike. It remains an ideal choice among lovers of fast driving and off-road driving. The main advantage of e-bikes with a carbon frame is exceptional shock and vibration damping, they resist corrosion and wear very well and, compared to other materials, they excel in their low weight.
