摘要： A bicycle suspension system includes a control unit, a velocity sensor, and a cadence sensor. The control unit is configured to obtain gear ratio information of a bicycle to control an operating state of a suspension of the bicycle based on the gear ratio information. The velocity sensor is configured to detect a forward velocity of the bicycle and output a signal indicative of the forward velocity to the control unit. The cadence sensor is configured to detect a cadence of the bicycle crank and output a signal indicative of the cadence to the control unit. The control unit is configured to obtain the gear ratio information based on the forward velocity and the cadence.

摘要： A bicycle crank assembly includes a crank arm and at least one sprocket. The sprocket includes a set of regular teeth and a set of first and second teeth. The first teeth have a first chain engaging tooth width for engaging outer links of a bicycle chain. The second teeth have a second chain engaging tooth width for engaging inner links of the bicycle chain. The first chain engaging tooth width is greater than the second chain engaging tooth width. The regular teeth have a third chain engaging tooth width being smaller than the first chain engaging tooth width. The regular teeth are disposed along at least one of top and bottom dead center areas with respect to the crank arm. The first and second teeth are disposed along at least between the top and bottom dead center areas with respect to the crank arm.
