ABSTRACT:
A three-wheeled scooter includes a reciprocating treadle drive which a rider may use to propel the scooter in either the forward or rearward direction. The treadle drive includes a pair of treadles having their rear ends mounted to crank portions of a rear crank drive axle and their forward ends supported by rollers from a bar track having a generally flattened portion therein along with an inclined portion. Movement is achieved by a rider's shifting of his weight alternately from one treadle to the other as each treadle rotates into a driving orientation. The treadle drive is characterized by maintaining a driving relationship between at least one treadle and the crank axle at all times to thereby eliminate any "dead spots".
