A vehicle for infants includes a footboard, a chassis with front and rear chassis supports, two front wheels, at least one rear wheel, a bar extending vertically from the front chassis support, a handle extending from the bar to be gripped by the vehicle's user, and optionally a removable seat. The vehicle is steered by the user's particular application of weight applied to the footboard in which the application of more weight to one side of the footboard (or the shifting of weight) causes the front wheels of the vehicle to steer the vehicle in the direction of that side.

An apparatus including an upper post, a main post, a control tube, a tension spring, and a hydraulic reset. The upper post can include a compression spring. The main post can be configured to telescopically mate with the upper post. The control tube can be rotably coupled to the main post. The tension spring can be configured to pull the upper post to the main post. The hydraulic reset can be configured to compress the compression spring. The upper post and the control tube can be configured to selectively lock the upper post to the control tube at at least two positions. In a first position of the control tube, the control tube can be configured to engage the compression spring. In a second position of the control tube, the control tube can be configured to disengage the compression spring.

Bicycle frames having rear stays that extend past the seat region and connect directly to the top region without being rigidly connected to the seat region. Some bicycle frames according to the present disclosure have a greater vertical compliance than comparably sized standard diamond frames having seat stays that are connected directly and rigidly to a seat tube.

A shock-absorbing seat stay for a bicycle includes a seat tube connecting mount having a first coupling portion with a first through hole, an extension member, a shock-absorbing member and a fastening unit. The extension member has a second coupling portion with two connecting lugs each having a second through hole in alignment with the first through hole. The shock-absorbing member is made of elastic material and clamped between the first and second coupling portions. The shock-absorbing member is a U-shaped member having two arms each having a third through hole. The fastening unit is inserted in the first through hole, the second though holes and the third through holes to connect the first coupling portion, the second coupling portion and the shock-absorbing member together. The seat stay is light weight and has a proper shock-absorbing function.

A stabilizing device for a handcycle has an axle including an inner shaft and an outer shaft. A first stabilizing component is coupled to the inner shaft. A second stabilizing component is coupled to the outer shaft in proximity to the first stabilizing component. A locking component is configured to engage the first and second stabilizing components to reversibly reduce rotation of the inner shaft with respect to the outer shaft. Alternatively, a stabilizing device for a handcycle has a frame including first and second stabilizing members affixed to the frame. A locking member is configured to engage the first and second stabilizing members to stabilize the frame. The stabilizing components or members include receptacles, teeth, or a friction component. The locking component or member includes a pin or knob configured to adjust the first or second stabilizing member into a locked position.

A bicycle assembly can include a bicycle frame that can have a main frame, a sub-frame and a shock absorber. The sub-frame can move in relation to the main frame and the shock can be used to regulate that relationship. A extension body can be used to establish a rear pivot point of the shock absorber. In some embodiments, the extension body can also be used to adjust the length of the combined shock absorber and extension body.
