A belt drive pulley system termed a “flip drive” is configured to provide at least two belt drive pulleys that are co-axially and integrally arranged and share common axle/bearing and mounting components. By being co-axially disposed, the belt drive pulleys will operate in separate and distinct planes. The flip drive is adapted for use in various applications so that power received on its first pulley from a first belt drive is transferred from its second pulley to a second belt drive (where the first and second belt drives are not co-planar).
