+As part of the product development course at UC Berkeley, the team developed HyperVaal, a cost-effective, universal e-bike conversion kit that transforms any standard bicycle into a pedal-assist electric bike. The system directly powers the crankset to leverage a bike’s existing gearing, using a compact drivetrain module that includes a 750W BLDC motor, custom reduction gearing, and a user-tunable mobile app. Key innovations include a modular mounting system compatible with over 95% of commuter bikes and a structural design that combines laser-cut steel and 3D-printed components for manufacturability and affordability
