Abstract

A wireless control system for a bicycle may include a base part attachable to a bicycle and a movable part. The control system may also include an electric motor disposed on the electromechanical component and a control unit disposed on the electromechanical component for operating the electric motor to operate the electromechanical component, the control unit including a wireless receiver. The control system includes a wake sensor connected to the control unit, the wake sensor configured to communicate a wake signal to the control unit.

First claim

The invention claimed is:

1. A control system for a bicycle, comprising:
a shift actuator;
a modifier actuator; and
a first control unit configured to generate a first signal responsive to actuation of the shift actuator, to generate no signal responsive to the actuation of the modifier actuator, and to generate a second signal responsive to actuation of the shift actuator and the modifier actuator concurrently.

2. The control system of claim 1 , further comprising:
a second control unit located in a first bicycle component, wherein the first signal is transmitted wirelessly by the first control unit to the second control unit.

3. The control system of claim 2 , wherein the first bicycle component is at least one of a rear gear changer and a front gear changer.

4. The control system of claim 3 , wherein the first signal is a shift signal.

5. The control system of claim 4 , wherein the first signal causes a shift of at least one of the rear gear changer and the front gear changer.

6. The control system of claim 1 , wherein the second signal is a different type of signal than the first signal.

7. The control system of claim 6 , wherein the second signal is at least one of a shift alignment signal and a trim command.

8. The control system of claim 7 , further comprising:
a second control unit located in a first bicycle component, wherein the second signal is transmitted wirelessly by the first control unit to the second control unit.

9. The control system of claim 8 , wherein the first bicycle component is at least one of a rear gear changer and a front gear changer.

10. The control system of claim 9 , wherein the first control unit is configured to transmit the second signal by at least one of ANT and BLTE protocols.

11. A control system for a bicycle, comprising:
a shift actuator having a pressed and released state;
a modifier actuator having a pressed and released state; and
a first bicycle component configured to perform a first action responsive to the pressed and released state of the shift actuator, no action responsive to the pressed and released state of the modifier actuator, and a second action responsive to the pressed and released state of the shift actuator and the modifier concurrently.

12. The control system of claim 11 , wherein the first bicycle component is at least one of a rear gear changer and a front gear changer.

13. The control system of claim 12 , wherein the first action is a shift and the second action is not a shift.
