Kappstein 2-Speed Hub | Wireless Electronic Shifting

The Kappstein 2-Speed Hub integrates two gear ratios, wireless electronic shifting and an internal mini dynamo into a compact rear-hub architecture. The system provides 1:1 and 1:1.57 ratios while retaining compatibility with standard cassette interfaces.

Shifting is controlled wirelessly and powered by the integrated mini dynamo, eliminating the need for an external battery or charging connection.

A Whisper Tech clutch provides low-noise engagement and low freewheeling resistance, while the internal transmission extends the usable gear range without adding an external gearbox.
