  • Patent number: 5426997
    Abstract: A drive assembly is provided for a multi-speed pedal drive bicycle that allows the bicycle's gears to be shifted even when the pedals are not being trod upon. This advance in multi-speed bicycles is accomplished through a new front chain ring that is capable of freewheeling with respect to a crank axle in combination with the employment of a friction plate between the rear wheel hub and the rear freewheel cassette allowing 1:1 transmission of the rotation of the rear wheel to the rear freewheel cassette which continuously moves the chain of the bicycle provided the bicycle is moving.
