US 2026/0048814 A1 · PROPULSION SYSTEM FOR USER-PROPELLED VEHICLES

Abstract

The present invention discloses a propulsion system that could be retrofitted to a user-propelled vehicle, such as a bicycle or kick scooter vehicle, primarily powered by the user's physical effort. The system is designed to capture and convert kinetic energy generated by the user's movements into electrical energy, which is used to assist in propelling the vehicle. The propulsion system comprises a first motor located near a wheel axle of a first wheel assembly at a front portion of the vehicle. The first motor captures and converts kinetic energy into low-voltage electrical energy. The low-voltage electrical energy is then boosted by a transducer and converted to alternating current (AC) by an inverter. The AC power is sent to a throttle module, which enables to control a second motor that assists in propelling the vehicle. The propulsion system enhances the vehicle's efficiency, providing additional propulsion based on the user's input.
