Cosmosworks × BAFANG
Cosmosworks is working closely with BAFANG to develop a pedal-assist conversion kit built around a hub-drive motor and a bottle-style battery. It is designed to upgrade a conventional road bike to a high-performance e-bike without damaging the bike. The motor uses a robotics-derived core and is intended to raise the bar for e-bike hub-drive motors. Development updates will be shared on our social channels. — Cosmosworks Product Team
