Zusammenfassung:	The utility model provides a speed-change rickshaw with a front and back pedal. The utility model is composed of a frame, a front wheel, a back wheel, a guiding mechanism and a driving mechanism. The driving mechanism thereof comprises a driving gear connected with a pedal crank, a big driven gear and a small driven gear arranged on the back axle, a guide wheel and a driving chain. When the rickshaw is pedaled forward, the small driven gear is stressed and is in the high speed state. When the rickshaw is pedaled backward, the big driven gear is stressed and is in the low speed state. The utility model has the advantage of simple speed-change structure which can ease the feeling of riding fatigue.
