Bicycle transmission control device

A bicycle transmission control device comprising:

• a controller configured to control an operating speed of a bicycle derailleur based on a running speed of a bicycle and a gear ratio of the bicycle, wherein
• the operating speed includes a first operating speed and a second operating speed that is different from the first operating speed;
• the controller is configured to control the operating speed so that the operating speed is the first operating speed in a state where the running speed is a first running speed and the gear ratio is a first gear ratio;
• and
• the controller is configured to control the operating speed so that the operating speed is the second operating speed in a state where the running speed is a second running speed and the gear ratio is a second gear ratio.

A bicycle transmission control device comprising:

• a controller configured to control an operating speed of a bicycle derailleur based on a running speed of a bicycle and a gear ratio of the bicycle;
• and
• a memory configured to store a related information with respect to the running speed of the bicycle and the gear ratio of the bicycle, wherein
• the related information includes a table;
• the table includes a first region and a second region that is delimited from the first region by a boundary;
• the operating speed is a first operating speed in the first region;
• the operating speed is a second operating speed in the second region;
• and
• the controller is configured to change the boundary depending on a cadence of a crank arm of the bicycle.

A bicycle transmission control device comprising:

• a controller configured to control an operating speed of a bicycle derailleur based on a running speed of a bicycle and a gear ratio of the bicycle, wherein
• the operating speed includes a first operating speed and a second operating speed that is different from the first operating speed;
• the controller is configured to control the operating speed so that the operating speed is the first operating speed in a state where the running speed is a predetermined running speed and the gear ratio is a predetermined gear ratio while a cadence of a crank arm of the bicycle is a first cadence;
• and
• the controller is configured to control the operating speed so that the operating speed is the second operating speed in a state where the running speed is the predetermined running speed and the gear ratio is the predetermined gear ratio while the cadence of a crank arm of the bicycle is a second cadence that is different from the first cadence.

A bicycle transmission control device comprising:

• a controller configured to control an operating speed of a bicycle derailleur based on a running speed of a bicycle and a gear ratio of the bicycle, wherein
• the operating speed includes a first operating speed, a second operating speed and a third operating speed;
• each of the first operating speed and the third operating speed is different from the second operating speed;
• the controller is configured to control the operating speed so that the operating speed is the first operating speed in a state where the running speed is a first running speed and the gear ratio is a first gear ratio;
• the controller is configured to control the operating speed so that the operating speed is the second operating speed in a state where the running speed is a second running speed and the gear ratio is a second gear ratio;
• and
• the controller is configured to control the operating speed so that the operating speed is the third operating speed in a state where the running speed is a third running speed and the gear ratio is a third gear ratio.
