Unicycle roller skate

Abstract

A unicycle roller skate includes a wheel frame, a wheel assembly, a shoe seat and a stabilization protective device. The wheel frame has a connection seat and at least one support section disposed under the connection seat, a connection hole/notch being formed at a bottom end of the support section. The wheel assembly includes a wheel body and a shaft member. The shaft member is passed through a center of the wheel body and locked at the connection hole/notch with a locking member. The shoe seat is fixedly connected with the connection seat. The wheel body has a rubber/plastic tire with an enlarged diameter. Therefore, the wheel body is more tolerant of bumpy road face. Accordingly, a user can easily and smoothly skate on a common bicycle lane without limitation to specifically treated site. The stabilization protective device serves to provide lateral support force and protection for a wearer's ankle.
