Phase gear and lever mechanism converts reciprocating power to rotary power with phase gear providing power stroke of greater duration than travel stroke so as to develop efficient power through a power stroke. A modified lever and gear mechanism converts reciprocating power to rotary power at variable out power ratio. Both converting mechanisms are applied as bicycle drive mechanisms. Both mechanisms are applied together in a bicycle one as a drive mechanism, the other for synchronizing the drive mechanism. |
