A bicycle for driving downhill with a front wheel region, a rear wheel region, and a support rod which couples the front wheel region and the rear wheel region, the support rod having at least one hinge for unfolding and folding and has a front rod portion between the front wheel region and the hinge and a rear rod portion between the rear wheel region and the hinge, a foot rod is pivotably mounted with a coupling portion to the support rod and has a footrest region for resting feet of a user of the bicycle, and the bicycle includes a tension rope system having a first rope tensioning portion and a second rope tensioning portion, wherein the first rope tensioning portion is coupled to the foot portion and the front rod portion, and the second rope tensioning portion is coupled to the foot portion and the rear rod portion.

A balancing vehicle includes a wheel, a bracket, a frame, a shock absorbing member, pedals, a control rod, and a handle. The bracket is fixed to an axle of the wheel. The frame is slidably connected to the bracket through a slider fixedly connected to the bracket, so as to allow the frame to slide relative to the bracket. The shock absorbing member is disposed between the frame and the bracket, and is configured to cushion relative movement between the frame and the bracket. The pedals are fixed to the frame. The control rod is configured to move back and forth in a direction of travel. The balancing vehicle accelerates when the control rod is pushed forward in the traveling direction, and the balancing vehicle decelerates or retreats when the control rod is pulled backward in the traveling direction. The handle is coupled to a top of the control rod.

A motorcycle brake pedal lever includes a rod connected to a motorcycle and a base is connected to the rod. The base includes a bore. A pivotal member includes a first pivot and a second pivot extending toward different directions. The first pivot is pivotably connected to the bore of the base so that the pivotal member is pivotable about the first pivot. A peg includes a space formed therein, and the second pivot of the pivotal member is pivotably engaged with the space by a pin so that the peg is pivotable about pin and the second pivot. Multiple torsion springs are respectively mounted to the first and second. The torsion springs respectively contact the pivotal member, the base and the peg. The peg is returned relative to the pivotal member, and the pivotal member is returned relative to the base by the torsion springs.

A foldable pedal includes a connection member, a shaft, a pedal body, and an engagement device. The connection member includes a first and a second connection ends along a first axis. The shaft includes a first and a second ends. The first end is pivotally connected with the second connection end along a second axis perpendicular to the first axis, so that the shaft pivots with respect to the connection member. The pedal body includes a shaft bore receiving the second end. The engagement device is on the connection member and switches between engagement and release positions. At the engagement position, the engagement device is engaged with the first end, and the shaft is coaxial with the first axis. At the release position, the pedal body is foldable to the crank, preventing direct effect of pedaling force and reducing distance between the pedal and the crank.

The present invention relates to a coupling-assist device for a bicycle crank arm, comprising: a main body open through upper and lower portions, the main body having a space formed to receive a crank arm to be inserted; a handle member extending from a lower portion of the main body; a support frame including a fixing part formed on a lower portion thereof and coupled with the upper portion of the main body, and a position adjusting hole that is open through to allow a tool to be passed therethrough and connected to the crank arm, wherein the position adjusting hole enables adjustment of position of the tool in up and down directions; and a support means.

A product that may include a first axle assembly that may have a lock shaft extendable from the first axle assembly. The lock shaft may be retractable into the first axle assembly. A second axle assembly may have a lock receiver into which the lock shaft may extend when the first and second axle assemblies may be aligned adjacent to one another

Disclosed herein is a folding bicycle comprising a handlepost joint and two joints in the mainbeam forward of the seat tube, wherein the pins of the hinges in the two mainbeam joints (i) are located on opposite sides of the mainbeam when viewed in a top view, and (ii) when the bicycle in folded, place the front wheel parallel to rear wheel and the wheel axles inline on the same lateral axis or on parallel lateral axes, wherein the wheels roll in parallel track.

A turning mechanism and a handle. The turning mechanism comprises: a first connecting rod (201) and a second connecting rod (202); the first connecting rod (201) is provided with a first bevel end, the second connecting rod (202) is provided with a second bevel end, and the second bevel end matches with the first bevel end, so that the second connecting rod (202) rotates along the end face of the first bevel end; in the rotating process, the first bevel can be attached to the second bevel, so that no gap exists between the first connecting rod (201) and the second connecting rod (202).

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.

A quick-mount crank-pedal mechanism for a children bicycle is provided. The quick-mount crank-pedal mechanism is composed of the following two parts including a crank rod and a crank bearing. The crank rod and the crank bearing are fitted with each other. With the mechanism, a pedal is enabled to be in a usable state quickly without using any tools, and a tip of the crank is effectively protected from puncturing through a carton, thereby reducing potential safety hazards.
