Abstract
An e-bike interface is a hybrid wired/wireless e-bike control system that integrates wireless bicycle components into operation of an e-bike. The e-bike interface provides a frame-mounted control and display that is wired to, for example, an assist motor and a battery, and provides a wireless communication bridge between wireless bicycle components and corresponding wireless controls located on a handlebar.
Claims22
An interface comprising:
- a housing attachable to a first frame part of a bicycle having an e-bike motor system;
- a processor supported by the housing;
- a first communication interface and a second communication interface in communication with the processor, wherein the first communication interface is a wired communication interface, and the second communication interface is a wireless communication interface;
- and
- an input in communication with the processor and supported by the housing, the input being configured to generate a first control signal based on a first user input,
- wherein the processor is configured to:
- receive a second control signal via the second communication interface, the second control signal being generated by a control device attached to a second frame part of the bicycle based on a second user input;
- and
- control the e-bike motor system via the first communication interface, based on the first control signal and the received second control signal, the first control signal and the second control signal causing the e-bike motor system to perform different operations.

A bicycle communication apparatus for an e-bike, the bicycle communication apparatus comprising:
- a housing attachable to a top tube of a frame of a bicycle;
- a processor supported by the housing;
- a wired communication interface in communication with the processor, the wired communication interface being wiredly connectable to an e-bike motor system, the e-bike motor system including a drive motor;
- a wireless communication interface in communication with the processor, the wireless communication interface being wirelessly connectable to a control device attached to a handlebar of the bicycle;
- an input supported by the housing and in communication with the processor, the input being configured to generate a first control signal based on a first user input;
- wherein the processor is configured to:
- receive a second control signal from the control device attached to the handlebar of the bicycle via the wireless communication interface, the second control signal being for the e-bike motor system and being generated by the control device based on a second user input;
- and
- control the drive motor of the e-bike motor system via the wired communication interface, based on the first control signal or the received second control signal, the first control signal and the second control signal cause the drive motor to perform different operations.
