| 摘要 | The present invention relates to a novel concept bicycle in which both a front wheel (18) and a rear wheel (22) are formed of a wheel and a tyre and is rotatably installed in the respective guide rings (16, 20) fixed at a handle shaft (50) and a frame (12), respectively, and a left pedal (24) and a right pedal (26) make a seesaw movement by an elastic member (68). Fan-shaped gears (28, 30) of left and right pedals (24, 26) are engaged with an internal gear (42) fixed at the wheel of the rear wheel (22) through deceleration gears (32, 34), one-way gears (36, 38) and a spur gear (40) connected to and fixed at a shaft (72) of the one-way gears (36, 38). Thus, the front and rear wheels (18, 22) have no wheel shaft and no spoke, and the pedals (24, 26) make a seesaw movement to provide the rear wheel (22) with rotating force. | ||||||
