Abstract: A step sporting equipment with a double transmission mechanism, wherein a transmission mechanism and a treading mechanism are located on both sides of a frame body respectively. Each transmission mechanism at least comprises a front wheel disc, a rear wheel disc and a driving piece. Each treading mechanism is connected to the corresponding transmission mechanism. When the user treads on each treading mechanism, each treading mechanism can compel the corresponding transmission mechanism to work. In addition, as the front wheel disc and rear wheel disc are linked by a driving piece, there is higher moving phase. Therefore, with two transmission mechanisms, the dimensional discrepancy of elements resulted from tolerance can be tolerated effectively, and the step sporting equipment can remain in normal operation.

Abstract: A pedal scooter transmission mechanism capable of increasing more motion energy in the pedal scooter, comprising a driving chainring pivotally connected to a proximity of a middle section of the deck, wherein the driving chainring is connected with the driven chainring via a transmission element, whereby the rear wheel and the driven chainring are being driven; two pedal mechanisms, every pedal mechanism comprising a pedal which is horizontally installed on both sides the deck near the middle section, and drives the center axle by a driving connecting rod assembly, wherein the total length of driving connecting rod assemblies is different, so that one of the pedal can generate more torque force and make the pedal scooter produce more motion energy.

Abstract: A pedal-driven scooter includes a frame, a head tube, a driving mechanism and two pedals. The pedals can move alternatingly to power the driving mechanism and making the rear wheels to roll. Therefore, a user can standing on the pedals to operate the scooter without kicking the floor as the conventional scooter.
