The crossbar includes a first folding arm and a second folding arm; the first folding arm is movably connected to the front folding wheel frame by means of the first pivot portion; the front folding wheel frame rotates about the first pivot portion and can move relative to the first folding arm; the second folding arm is movably connected to the rear folding wheel frame by means of the second pivot portion.

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 quick-release structure includes a fork, a clamping unit, and a quick-release unit. The fork has a receiving space. The clamping unit includes a base, a plurality of arc-shaped clamping members, an elastic ring, and a shaft cover. The base is fixed in the receiving space. The base has a circular cavity. The circular cavity is provided with a plurality of elongated grooves. The arc-shaped clamping members each have a first axle to slide in a corresponding one of the elongated grooves and a second axle. A center of the arc-shaped clamping members is formed with an adjustable clamping opening. The shaft cover is formed with a plurality of axle grooves arranged annularly. The second axles of the arc-shaped clamping members are pivotally connected to the respective axle grooves. The quick-release unit has a shaft. After the shaft passes through the adjustable clamping opening, the adjustable clamping opening subjected to the elastic force of the elastic ring is retracted to clamp the shaft.

A crank preload collar assembly is disclosed. The crank preload collar assembly includes a preload collar body having an axial opening therein to fit around a spindle of a crank assembly. The crank preload collar assembly also includes a clampable opening formed in a portion of the preload collar body. A cam lever is coupled with both sides of the clampable opening, wherein the cam lever provides a clamping force to the preload collar body with respect to the spindle.

In an aspect, a pivot joint for a collapsing foot-deck-based vehicle is described, comprising a foot deck, at least two wheels coupled to the foot deck, and a handlebar assembly coupled to the foot deck via a locking pivot joint, also referred to as a locking swivel joint, the handlebar assembly comprising at least one handle, the locking pivot joint having a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels, the handlebar assembly being selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck and a collapsed configuration in which the handle is generally proximal to the foot deck.

A bicycle wheel quick release device capable of being combined with a tool has a quick release assembly and a handle. The quick release assembly has a shaft, an axial hole, and a cap. The cap has a receiving groove communicating with the axial hole. The handle is capable of being received in the axial hole and the receiving groove and has at least two tool portions. Any one of the at least two tool portions is capable of being combined with a threaded component to screw or unscrew the threaded component onto or from an object. Thereby, the handle is a multifunctional tool that can be used not only as a wrench for detaching or mounting the quick release assembly from or onto a bicycle frame but also as a wrench for other threaded components.

A quick-release device for a bicycle includes a shaft having a locking assembly at one end and an inner sleeve in another end. The inner sleeve is kept a distance apart from an end edge of a through hole of the shaft to form an inner annular trough portion at an outer end of the through hole. A threaded cylinder is insertedly connected to the inner annular trough portion. A perforation is defined in the threaded cylinder. One axial end of the threaded cylinder has a cylindrical flange. The cylindrical flange is insertedly connected to the inner annular trough portion of the shaft. A bolt is insertedly disposed in the perforation of the threaded cylinder. The bolt passes through the perforation and is inserted into the shaft to be screwed to the inner sleeve, so that the bolt presses and locks the threaded cylinder and the shaft.

An axle assembly, including: an axle sleeve having first end face; a second end face axially spaced from said first end face and an axially extending opening therethrough;a control shaft assembly including: a control shaft and an engagement element having an engagement surface. The engagement element is axially retained to the control shaft. The control shaft assembly extends within the opening to be axially overlapping the axle sleeve. The engagement element has a restraining engagement with the axle sleeve at an engagement interface between the engagement surface and opening; the restraining engagement providing a restraining resistance to restrain axial displacement between the control shaft and axle sleeve. The engagement element fully circumscribes the control shaft about the axial axis and is radially self-supporting.

A quick-release clamp for a vehicular mount or rack having a rigid stationary first jaw with a clamping surface, and a rigid second jaw opposite with a clamping surface oriented to face the first jaw clamping surface. The second jaw is movable between an open and a closed position relative to the first jaw, where the closed position is capable of retaining one or more objects to be clamped transversely between said jaws. A lever, attached to a variable tensioning system operates to open and close the jaws when sufficient force is applied to overcome the tension of the tensioning system.
