Enviolo TR Trekking Hub – Stepless shifting for trekking and hybrid bikes
 The Enviolo TR Trekking hub is specifically designed for longer rides, versatile use, and e-bikes with powerful mid-drive motors. Thanks to its innovative Continuously Variable Planetary (CVP) technology, you can shift seamlessly without fixed gears, even under load or while stationary. With a 380% gear range and a maximum torque of 85-90 Nm, this hub is ideal for trekking bikes, hybrid bikes, and powerful electric bikes. The hub is low-maintenance, quiet, and suitable for both manual and automatic (Automatiq) operation.

 The difference from the previous TR Trekking model is that the housing has been modified to be completely symmetrical. This means the spoke length is the same on both sides with a symmetrical rim. It also features a newer freehub body that secures the sprocket with a lockring instead of a snapring.

 Key Features:

 
 Infinitely variable shifting with 380% range (0.5–1.9)
 
 Maximum vehicle weight: 180 kg
 
 Maximum torque: 85-90 Nm, suitable for powerful e-bike motors such as Bosch Performance Line CX
