A bicycle includes a frame, a charging circuit carried by the frame and configured to capture energy associated with movement of the bicycle, a power module carried by the frame, and a switch disposed electrically between the charging circuit and power module. The power module, in response to an indication that the bicycle is being braked or travelling downhill, closes the switch to enable energy transfer between the charging circuit and power module. The charging circuit may also be connected to the power module if it is detected that power is demanded, or if the rate of pedalling falls below a threshold value. In an embodiment, the charging circuit employs rim-mounted magnets (195, figure 2) and frame mounted coils (185, figure 2) to generate current. |
