초록

A number of embodiments of an electrically assisted manually powered bicycle that utilizes a control means whereby the operation of the electric power assist is curtailed when the battery voltage drops below a lower threshold value. Means are also provided to gradually reduce the electrical power assist prior to this so as to more smoothly transition to a nonpower assisted operation.
