Title:
POWER-ASSISTED BICYCLE WITH PHYSICAL STRENGTH BUILDUP FUNCTION
Document Type and Number:
WIPO Patent Application WO/2005/100144
Kind Code:
A1
Abstract:
A power-assisted bicycle, wherein the rotor shaft (61a) of a generator-motor (61) is connected to a transmission device (M) between a crankshaft (17) and rear wheels (10r), an arbitrarily disengageable and engageable clutch (46) is interposed in a transmission route between the generator-motor (61) and the rear wheels (10r), and a mode selector means (91, 92, 99) is installed to arbitrarily switch an operation mode between a power-assist mode for generating power in the generator-motor (61) and a charging mode for charging, to a battery (90), a power generated in the generator-motor (61) due to a back load to the rotor shaft (61a) to a battery (90). Thus, when the mode selector means is switched to the charging mode with the clutch (46) disengaged, a physical strength buildup training can be performed while a charging from the generator-motor (61) to the battery (90) is performed in a stationary state. Namely, the power-assisted bicycle with physical strength buildup function thus provided can be used not only for the light movement of a rider but also as a stationary training appliance for building up the physical strength of the rider by applying a load on the pedals thereof in a stopped state.
