Abstract

Claims (20)

1. A method for controlling electronic shifting of a bicycle, the method comprising:

identifying, by a processor, an average torque over a period of time;

comparing, by the processor, the average torque to a threshold torque level;

enabling, by the processor, automatic shifting of the bicycle based on the comparison and the average torque exceeding the threshold torque level; and

initiating, by the processor, electronic shifting of the bicycle, the initiating of the electronic shifting of the bicycle comprising actuating an assist motor of the bicycle for electronic shifting of the bicycle.

2. The method of claim 1 , wherein identifying the average torque comprises:

receiving, by the processor, torque data.

3. The method of claim 2 , wherein the torque data comes from torque sensors on a crank assembly.

4. The method of claim 1 , wherein the period of time is five seconds.

5. The method of claim 1 , wherein the period of time is less than five seconds.

6. The method of claim 1 , further comprising:

disabling, by the processor, automatic shifting when a wheel speed of the bicycle is zero.

7. The method of claim 1 , wherein electronic shifting of the bicycle is initiated without a user input.

8. The method of claim 1 , further comprising:

maintaining, by the processor, automatic shifting once automatic shifting is enabled until a wheel speed of the bicycle is zero.

9. The method of claim 1 , further comprising:

receiving, by the processor, a first wheel speed of a first wheel;

receiving, by the processor, a second wheel speed of a second wheel;

comparing, by the processor, the first wheel speed and the second wheel speed;

disabling, by the processor, automatic shifting of the bicycle based on the comparison and the first wheel speed not being within 0.1 revolutions per minute (RPM) of the second wheel speed.
