Twin Transmission technology for e-bikes

An e-bike powertrain using Twin Transmission technology to improve technical performance and user safety

The solution is a twin transmission technology (TT) and has reinvented the electric bicycle. It combines a classic chain transmission (right side) that relays efficiently the pedalling effort, and a fully independent electric transmission (left side) that does not offer permanent assistance but rather a "boost" managed manually by a throttle on the handlebar. Lighter and more powerful than traditional e-bikes on the market, WhaTT bikes allow you to reconnect with the pleasure of pedalling, while revolutionising the use of the electric motor in the fields of performance and safety
