Abstract

The utility model provides a heavy scooter, which consists of a scooter frame, a handle, a central framework, a front wheel, more than one rear wheel, two pedals, two racks, two ratchet flywheels, a transmission mechanism, and two sliding connecting rod sets. The transmission mechanism comprises a drive gear, an idle gear, and a driven pinion. The two sliding connecting rod sets comprise a pair of four-connecting rod mechanisms, four pedal-supported slide rods and four groups of pulley components. With the utility model, a rider can step on the pedals alternately according to the weight of the rider himself or herself, and then the racks transfers the torque to the ratchet flywheels to rotate a drive shaft. Moreover, the torque is transferred to the components of the rear wheel via the transmission mechanism to move the motorbike forwards. As a rider steps vertically on the pedals up and down repeatedly, the riders can stand on the motorbike for stable operation, which is both relaxing and funny. Moreover, the safety for the rider is promoted compared with riding a single bicycle. In addition, the utility model can be mass-produced and commercialized easily.
