BICYCLE MOTOR CONTROL SYSTEM
First Claim
1. A bicycle motor control system, configured to control a drive motor that outputs drive force to a rear wheel that is provided on a bicycle comprising a crankshaft that outputs manual drive force to the rear wheel via a sprocket and a chain, the bicycle motor control system comprising:
- a controller configured to control the drive motor that is configured to selectively output driving force in accordance with the manual drive force, and cause the drive motor to stop when a detected manual drive force, sensed by a manual drive force sensor, falls below one of a plurality of predetermined force threshold values, which are set stepwise in accordance with a crank angle of the crankshaft, the crank angle being sensed by a crank rotation sensor.
