Apache gear sensor Gearsensor GS1-F-Z309AG for BBS
The gear sensor briefly cuts the motor when you shift to an easier or harder gear, so shifting never happens under full load. This better protects all drivetrain components.
The sensor is installed on the rear derailleur shift cable. It is compatible with all types of BBS mid-drive motors and plugs into the EB-BUS cable in place of a brake lever. Cable length 350 mm.
A gear sensor is a recommended add-on for a mid-drive motor with an external derailleur, and an essential part when using an internal hub gear in the rear wheel.
