The 90T motor has a patented helical gear structure for low noise, smooth and powerful riding. This allows for better handling and stability, especially for riders who prefer a more natural feel when riding. With threads for both a flywheel and a belt, the e-bike belt motor offers a low-maintenance, durable, quiet and efficient alternative to traditional chain drives. It is ideal for commuters, city riders and those seeking a smooth, clean, reliable ride with minimal maintenance.
