A steering assembly for a vehicle includes a track pivotable about a steering axis, a slider slidably connected to the track, a handlebar connected to the slider, a lock actuator movable between a locked position and an unlocked position, and a rocker operatively connected to the lock actuator. The rocker is pivotable about a rocking axis relative to the slider. The handlebar, the slider, the lock actuator and the rocker are pivotable about the steering axis with the track. In the unlocked position of the lock actuator, the rocker and the handlebar are slidable along the track with the slider. In the locked position of the lock actuator, the rocker presses the slider against the track and thereby locks the slider, the rocker and the handlebar in position relative to the track.

A bicycle hub assembly comprises a sprocket support body. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

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.

The main structure of the present invention comprises: a carrying-frame set with a cargo-carrying structure, direction-guiding wheels, and a connection component comprising a sleeving-connection element and a quick-dismantling component; wherein the connection component is provided for connecting a power-providing frame set with an adjustment component comprising an assembly-connection element and a connection portion, and a steering component is set at the side of the connection component. Thereby, the user can adjust the distance between the carrying-frame and the power-providing frame to achieve the advantage of saving the accommodation space through the steering component.

In an aspect, a collapsing foot-deck-based vehicle is provided and includes a foot deck, at least two wheels coupled to the foot deck, and a handle structure coupled to the foot deck via a locking pivot joint. The handle structure includes at least one handle. The locking pivot joint has a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels. The handle structure is selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck for gripping by a rider of the foot-deck-based vehicle, and a collapsed configuration in which the handle is generally proximal to the foot deck.

In traditional bicycle pedals, the mechanism that maintains a pedal's rocking synchronicity with the rotating crank consists of a spindle that extends in the interior of the pedal's cylindrical housing that is typically furnished with ball bearings, a washer, and a nut at the endmost part of the pedal to secure all of its axle components in place. To attach to the crank arm, the right side pedal spindle typically has a right-hand thread and removes counterclockwise while installs clockwise, and the left side pedal spindle has a left-hand thread that removes clockwise and installs counterclockwise. The present invention facilitates the mounting of bicycle pedals by using a square end (i.e. the four flat sides to the mounting end of the spindle) and a ball-lock mechanism to secure the pedal to the crank arm.

A bicycle apparatus with interchangeable front fork is disclosed. The bicycle comprises a frame and a quick release assembly for securing the removable front fork attachment assembly to the bicycle frame's head tube. The interchangeable front fork attachment assembly and quick release assembly allows for the quick interchanging of front fork with varying attachments which utilize different methods to achieve motion.

A suspension for a two-wheeled vehicle includes first and second fork legs. Each fork leg includes a dropout. Each dropout has an opening therethrough. At least a portion of one of the openings is threaded. Each of the dropouts includes a split-damp pinch bearing defining the opening and operable between an open position and a locked position, and a hand operable actuator pivoted to the bearing for operation thereof. The suspension further includes a one-piece axle. The axle is disposed through the openings. The axle has a threaded first end engaged with the threaded portion. The axle has an ergonomic grip formed at a second end. The bearing tightly engages an outer surface of the axle in the locked position, thereby rotationally coupling the axle to the dropout.

A bicycle wheel securing device comprises a shaft, an axial abutment structure, a bicycle-body engaging structure, a manual actuator, and a shaft-end retaining structure. The shaft has a first shaft end, a second shaft end, and a longitudinal center axis. The manual actuator is operatively connected to the axial abutment structure to bias the axial abutment structure against a first wheel attachment part of a bicycle body in response to operation of the manual actuator in a securing state where the bicycle-body engaging structure is engaged with a second wheel attachment part of the bicycle body. The shaft-end retaining structure is at least partly disposed at the second shaft end to retain the second shaft end in the first wheel attachment part in a maintenance state where the second shaft end is positioned in the first wheel attachment part of the bicycle body.

A quick-release clamping mechanism secures two objects and rapidly attaches or detaches to secure the objects to one another in a rigid, repeatable manner. The mechanism is formed from two interconnecting contiguous pieces of material, free from hinges or other attachment devices. The first contiguous piece is attached to a first object, and the second contiguous piece is attached to a second object to be secured to the first object. The piece that forms the first profile can be a rail with a male protrusion. The piece that forms the second profile can be a rail with a female cavity that receives the male protrusion. The mechanism also includes a retention channel, a clamp bar, and a tension device that applies tension to the clamp bar to secure the mechanism. A secondary retention mechanism is provided to prevent separation of the components if the primary locking feature is disengaged inadvertently.
