Taiyo Yuden Feremo: The 1,000-Kilometer Electric Bicycle

Japan's Taiyo Yuden developed the Feremo system, enabling e-bikes to travel up to 1,000 km on one charge. Using a front-hub motor and smart controller, it maximizes energy regeneration during braking and descents. This high efficiency improves safety and battery range.The FEREMO™ (Future Energy REcycling system for MObility) technology achieves its 1,000 km range primarily through a highly efficient regenerative electric assist system that recovers and reuses kinetic energy.Key elements that enable this performance include:• Regenerative Braking and Coasting: When the rider brakes, coasts, or stops pedaling, the front-wheel hub motor generates electricity to recharge the battery. This system is claimed to be 30% more powerful in its regenerative capacity than existing market competitors.• Intelligent Energy Management: The system relies on an energy-saving controller that manages the motor and the charging/discharging process. It can maintain a set speed on downhills autonomously, acting as an engine brake while generating high levels of energy.
