This is the scooter that requires riders to step--instead of pedal--up and down on a pair of pedals for smooth forward motion. The scooter uses an innovative pedal recovery and drive system to transfer the force from each pedal downstroke into rear axle rotation. Two parallel offset crank shafts engage a pair of gears to produce the reciprocal pedal recovery, providing riders with smooth, comfortable downward strokes. A brake lever controls the front wheel's disc brake for confident stops. The three pneumatic tires provide grip on concrete, asphalt, or other hard surfaces. The handle bar extends to a maximum height of 45" using the locking pin adjustment. The scooter folds to 35" L x 16" W x 13" H for storage or commuting on a train. Sturdy aluminum alloy construction. Supports riders up to 180 lbs. 40" L x 16" W x 45" H. (27 lbs.)
