Enviolo hubs use the NuVinci planetary transmission to provide stepless shifting and near silent operation. Shift at any time- while pedaling, coasting or while stopped. Enviolo hubs are designed to withstand the high torque of an eBike while being visually maintenance-free. The Extreme Duty hub is optimized for businesses that bring their heavy cargo load (max. 300kg) to the next level. The perfect sustainable and maintenance-free cargo solution.
