One embodiment of a hands free bicycle maintenance pedaler provides means to the operator to have both hands free for adjusting, cleaning, lubricating, inspecting or locking the drive train components of a supported bicycle. One embodiment has a motor (1600) communicating with a power enclosure (1210) and a speed pedal (1205) to variably power said motor. Said motor frictionally engages with a motor plate (1500) through which an output shaft (1620) passes and frictionally engages with a crank interface arm (1700). Said crank interface arm contains a temporary connection means to a crank arm (190) using pair of connector rods (1745) along said crank arm. Said motor plate is pivotable and slidable along a carriage (1400). Said carriage is slidable along a tube (1300) or work stand (110) to achieve acceptable orientation between the device and an imaginary line through the center line of a bottom bracket of a bicycle.
