A gearing system for a vehicle comprises a first rotational input (12), a second rotational input (16) and a rotational output. The first rotational input and second rotational input transmit a rotation to the rotational output, wherein one of the first rotational input and second rotational input is connected to the rotational output through a one way clutch (60), and wherein the other of the first rotational input and second rotational input may be connected to the rotational output through an overrunning clutch (48), wherein said one way clutch and said overrunning clutch are coupled. The one way clutch is housed with a cylindrical housing (52f) of a bracket (52) comprising a first cylindrical section (52a) and a second cylindrical section (52b), wherein the second cylindrical section has a greater diameter than the first cylindrical section. The one way clutch may be a sprag clutch and the overrunning clutch may be a freewheel assembly. The vehicle may be an electric bicycle, but may also be another dual propulsion vehicle such as a hybrid car.
