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.
