A child carriage assembly includes a frame structure and a seat assembly secured to the frame structure which comprises four depending tubular legs. The end of each leg has a detent aperture. A wheel and axle assembly includes two large diameter and width hollow plastic wheels for use on sand pinned to an axle at opposite axle ends. A detent latching mechanism is rotatably secured to the axle adjacent each wheel for attachment to a different leg end. The mechanism has a housing with a leg receiving chamber and a spring lever in the chamber with a detent projection which resiliently engages the detent aperture in each leg inserted into the chamber. A locking pin releasably locks the leg to the housing. A brake is secured to the legs via a brace and a brake collar attached to the rear axle. The collar has apertures for receiving a sliding pin attached to the brace for precluding the axle and attached wheels from rotating.
