Definitions

  • Figure 9 is a side elevational view of a second type of bicycle upon which has been mounted the power assist apparatus of the present invention which incorporates a belt drive arrangement;
  • the clutch plate 162 connects together in rotative movement the driven pulley 1 60 and the rear wheel 136 when the driven pulley 160 is being rotated at the same speed (rpm) as the rear wheel 136. However, as was previously discussed, when the rotation of the rear wheel 1 36 is at a greater rpm than the driven pulley 160, the clutch will permit the rear wheel 136 to rotate freely relative to the driven pulley 160.
