A mini scooter includes a wheel member, a wheel support member, a steering rod, a steering rod support, a wheel cover plate, and a pedal. The wheel member includes a wheel with a transmission ring in the center, and a unidirectional rotary bearing, a pivot shaft of which serves as a wheel axle. Two ends of the wheel axle are respectively provided with cover plates. The cover plates are connected to the transmission ring. The wheel support member includes a wheel support with a top portion having a through hole and having an inverted U-shaped cross section. Securing bolts extend through through holes in the wheel support and engage with nuts. Two ends of the bearing pivot shaft are provided with axle bearings. Two sides of the wheel support respectively form circular holes for receiving the axle bearings. The wheel cover plate is disposed on and secured to the securing bolts in the through holes in the wheel support. The wheel cover plate has a top portion provided with front and rear stop blocks. A rear end of the wheel cover plate is connected to the pedal. The steering rod support includes a steering rod upper support and two steering rod side supports connected to two ends of the wheel axle and disposed on outer sides of the wheel support. Two steering rod side supports are respectively connected to the steering rod upper support. The steering rod is secured on a top portion of the steering rod upper support at a middle position such that when the steering rod swings forward and rearward, the swinging angles are limited within a range defined by the front and rear stop blocks.
