摘要： A device is provided for range adjusting bicycle pedals in a bicycle having a frame with a crank hub, a drive sprocket and drive chain. The device consists of a crank axle extending through the crank hub, with the drive sprocket mounted on the crank axle to operate the drive chain. A pair of crank arms extend in opposite directions from the crank axle. A pair of pedals are provided. A structure is for mounting each pedal in an adjustable manner to each crank arm, so as to change the distance of the pedals to the crank axle. Someone who cannot fit on a standard bicycle properly, such as a child, an adult and an elderly person that has limited knee, hip and ankle movement, can still pedal the bicycle. In addition, status-post surgical patients would also benefit from the range adjusting device. In a modification the crank arms are adjustable to the crank axle instead of the pedals to the crank arms.
