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 Heavy Duty hub is engineered for heavier loads over shorter distances with or without Ebike motors. Rated for up to 250 kg permissible vehicle weight and 100Nm nominal torque.
