Abstract: A scooter includes a connecting seat and a connecting bar extending rearward of the connecting seat, at least one rotatable front wheel and at least one rear wheel; a handle bar to control turning of front wheel; and a foot pedal connected to the connecting bar, the foot pedal having a left foot pedal portion and a right foot pedal portion; each of the left and right foot pedal portions being configured to support a rider's left foot and right foot, respectively, to lie substantially parallel to the connecting bar. The front wheel has a diameter, and the front and rear wheels are spaced apart a lateral distance, and wherein a ratio of the diameter to the lateral distance is selected to allow a rider to propel the scooter along flat ground without pushing the feet along the ground. The front wheel may have a rounded shape as seen from front view to establish substantially tangential line contact with a rolling surface.

Abstract: A scooter comprises a main frame, a handle bar arranged in front of the main frame and extending upward, a handle mounted at the upper end of the handle bar, and a front wheel and a rear wheel arranged below the main frame, the main frame including a connecting seat in the front thereof used for connecting with the handle bar, and a connecting bar extending backward from the connecting seat, with the connecting bar provided on the left and right sides with a left pedal and a right pedal extending outward, respectively. While pedaling, a pedaler alternatively pedals on the left and right pedals with both feet, which changes the traditional way of pedaling with one foot in the front and the other in the rear, and has better stability and higher pedaling speed.
