In a bicycle with an internal combustion engine having a frame, a front wheel, a rear wheel, a pedal crank shaft connected to the rear wheel for manual drive thereof, the engine being connected to the rear wheel for power drive thereof, an improvement comprising first means for producing an output related to drive speed imparted to the rear wheel by the pedal crank shaft, second means for producing an output related to drive torque imparted to the rear wheel by the pedal crank shaft, and third means responsive to the outputs of said first and second means for controlling a throttle member of the engine.
Claim 3
Dependent Claim
31 words
The improvement as claimed in claim 1 comprising a gear train between said pedal crank shaft and said rear wheel, said first and second means being coupled to said gear train.
Claim 4
Dependent Claim
86 words
The improvement as claimed in claim 2 wherein said gear train comprises an input gear coupled to said pedal crank shaft, an output gear coupled to said rear wheel, and an intermediate gear coupling said input and output gears, said second means comprising a rotatable support shaft for said intermediate gear which turns in proportion to the torque applied through the intermediate gear, said first means comprising a rotary shaft coupled for rotation with the intermediate gear to be turned in correspondence with the rotation thereof.
