A toy vehicle for children, comprising a vehicle frame (1), a steering rod (4) extending in the vertical direction, and a front wheel component (2) provided at the bottom of the steering rod (4). The vehicle frame (1) comprises a main vehicle frame (1) provided with a seat mechanism (7), a left frame (12) provided at the rear with a left rear wheel component (31), and a right frame (13) provided at the rear with a right rear wheel component (32). The left frame (12) and the right frame (13) respectively are rotatably connected to the rear part of the main vehicle frame (1). The left rear wheel component (31) and the right rear wheel component (32) are omnidirectional wheels. Also provided on the vehicle frame (1) are a driving mechanism used for driving the left frame (12) and the right frame (13) to rotate respectively relative to the main vehicle frame (1) so as to allow the left rear wheel component (31) and the right rear wheel component (32) to approach each other or to move away from each other, and an operating mechanism used for driving the movement of the driving mechanism.

A ride-on toy includes a handle unit; a front leg unit including a front leg and a front wheel mounted to the front leg; a rear leg unit including a rear leg and a rear wheel mounted to the rear leg; a pedal unit; a saddle unit; and a chassis. In a first state, in response to a first downward force applied to the saddle unit and a forward force applied to the handle unit, the front leg moves with the front wheel forward and away from the rear leg, and the rear leg stays still. In a second state, in response to a second downward force applied to the pedal unit and a rearward force applied to the handle unit, the rear leg moves with the rear wheel forward and toward the front leg, and the front leg stays still.

Adjustable speed effort-saving bicycle, comprising a front wheel assembly, a rear wheel assembly, and a frame, the front wheel assembly and the rear wheel assembly mounted on either front or rear end of the frame, also comprising quad-connecting rod mechanism, a chain wheel, chain A, and a transmission mechanism converting rider weight into a rocking force. The quad-connecting rod mechanism is mounted on the frame. The chain wheel is on the frame and meshes with middle part of chain A. The chain wheel is connected to the rear wheel assembly via transmission apparatus. One end of chain A is connected to an output frame-connecting rod of the quad-connecting rod mechanism. A bent part extends from where the output frame-connecting rod joins the frame. Another end of chain A is connected to the bent part. A tensioner for tensioning chain A is between the bent part and the output frame-connecting rod.

Extreme labor-saving bicycle, comprising a front wheel assembly, a rear wheel assembly, a handle, a pedal, a frame, a connecting rod, a swinging rod, a seat and a transmission mechanism for transferring force of the swinging rod to the rear wheel assembly, wherein, the front wheel assembly and the rear wheel assembly are mounted at front end and rear end of the frame, the pedal is rotatably mounted at lower end of the middle of the frame, the swinging rod and the pedal are hinged to two ends of the connecting rod, the seat is fixed at a hinging end of the connecting rod and the swinging rod, and one end of the swinging rod away from the seat, is hinged to=front end of the frame and=connected with the rear wheel assembly through the transmission mechanism.

A squat bicycle provides a squat bicycle in which a power transmission means and a frame are driven in a linked manner. The frame is configured to include a top tube, a down tube, a seat stay, and a chain stay. The front end of the top tube is hinge-coupled to the down tube, and the rear end is hinge-coupled to the seat stay. The seat stay is divided into a first member in which the front end is hinge-coupled to the top tube and a second member in which the rear end is hinge-coupled to the rear end of the chain stay, and a rear end of the first member is hinge-coupled to a front end of the second member.

A leg and arm powered vehicle incorporating a frame; a seat rollably mounted upon the frame for reciprocating motion; a wheel and propulsion sprocket combination mounted upon the frame for vehicle propulsions; a chain operatively engaging the propulsion sprocket, the chain having a pair of flights; a sprocket support member fixedly attached to the seat; rearward and forward drive sprockets, the rearward drive sprocket engaging one of the chain's flights; first rotatable mountable means attaching the rearward drive sprocket to the sprocket support member and being adapted for alternatively resisting counter-rotation of the rearward drive sprocket and permitting rotation of the rearward drive sprocket; second rotatable mounting means attaching the forward drive sprocket to the sprocket support member and being adapted for alternatively resisting counter-rotation of the forward drive sprocket and permitting rotation of the forward drive sprocket; and hand and foot engaging members fixedly mounted to the frame.

The present invention relates to a self-power generation-type electric bike, and particularly, to a self-power generation-type electric bike which can be applied to an electric bike (an electric bicycle, an electric motorcycle, an electric kick scooter, etc.) to generate air during travel, and use the air to produce electricity and travel for long periods of time without being charged.

A ride-on toy includes a handle unit; a front leg unit including a front leg and a front wheel mounted to the front leg; a rear leg unit including a rear leg and a rear wheel mounted to the rear leg; a pedal unit; a saddle unit; and a chassis. In a first state, in response to a first downward force applied to the saddle unit and a forward force applied to the handle unit, the front leg moves with the front wheel forward and away from the rear leg, and the rear leg stays still. In a second state, in response to a second downward force applied to the pedal unit and a rearward force applied to the handle unit, the rear leg moves with the rear wheel forward and toward the front leg, and the front leg stays still.
