Scooter without foot board has two forward foot supports and optimum seat position for both legs to propel scooter forward and rest in the ground when required

摘要

The scooter has two front foot supports, esp. pedal shafts, and a frame with handlebars, saddle, and two or more wheels. An optimum ergonomic pedal-seat-position is determined by a combination of the following factors:- A user sitting upright on the saddle can just about touch a forward foot support (2R,L) with his heel, when his leg is fully stretched. The hip joint is positioned above the ground at a height of approx. 0,75 to 1,05 of the outer length of that leg. When seen from the side, a geometric center (1) of the handlebar grips (1) is located approx. above the foot support. The scooter may have an additional auxiliary drive, esp. an electric drive.
