A ratchet hub device, which can be quickly meshed to drive a bicycle, includes a hub shell, a ratchet cylinder, and an axle. There are plural tooth sockets and two groups of receiving notches between the hub shell and the ratchet cylinder. The receiving notches of each of the two groups are arranged with an equal interval between each other. Each of the receiving notches of the one group is arranged next to one of the receiving notches of the other group. Two groups of receiving notches receive ratchet members therein and engage with the tooth sockets by turns. Thereby, when a rider re-pedals a bicycle, one group of the ratchet members engage with the near tooth sockets so as to quickly engage with the hub shell and drive the hub shell to rotate.

A child's riding vehicle can be quickly reconfigured between a balance bike configuration and a pedal-powered bicycle configuration, suitable for children of different ages, without removing any parts to be stored separately. The pedal crank arms can be repositioned on the crank and the pedal axles can be pivoted so that in the balance bike configuration: the pedal crank arms are positioned adjacent to one another and generally upward; the pedal axles are pointed mostly rearwardly but also slightly inwardly rather than extending transversely side-to-side; and the crank arms and pedal axles are telescoped in. The result is that in the balance bike configuration the pedals and crank arms are compacted and folded out of the way so as not to interfere with the child riding the vehicle.

The invention provides a horizontal type double-leg exercise rehabilitation machine which comprises a support, the interior of the support is hollow, the bottom of the support can stand on the plane,a driving wheel is installed in the support through a wheel shaft, and the two ends of the wheel shaft of the driving wheel are each connected with a connecting rod assembly through a crank. Each connecting rod assembly structurally comprises a pedal, a shank auxiliary rod, a thigh auxiliary rod and a support connecting rod. Two ends of the pedal are respectively connected with one end of the crank and one end of the shank auxiliary rod, the other end of the shank auxiliary rod is hinged with one end of the thigh auxiliary rod, and the other end of the thigh auxiliary rod is hinged with one end of the support connecting rod; the driving wheel drives the two sets of connecting rod assemblies to move through the crank, and therefore a user is helped to ride the bicycle.
