A shock absorption device includes first and second assemblies, at least one pivot component and a buffering component. The first assembly is adapted to be connected to a first component of a bicycle and has at least one conical hole. The second assembly is adapted to be connected to a second component of the bicycle. The pivot component is fastened on the second assembly and has a conical portion. The conical portion is inserted into the conical hole such that the first and second assemblies are pivoted to each other. The conical portion is leaned against and fitted on the conical hole. The buffering component is disposed between the first and second assemblies. When the first and second assemblies rotate relatively to each other by taking a central axis of the conical hole as a rotation axis, force between the first and second assemblies is buffered by the buffering component.

The invention relates to a bicycle, with a bicycle seat assembly rotatably connected to the bicycle. Rotation movement of the bicycle seat assembly is possible, seen in the driving direction, to the left and to the right side and is independent of the steering movement of the bicycle. The axis of rotation of the bicycle seat assembly is arranged in front of the axis of the bottom bracket, seen in the driving direction, and the seating surface of the bicycle seat is arranged behind the axis of the bottom bracket, seen in the driving direction. The rotatable bicycle seat assembly enables an upright riding position by dodging the cyclist's leg pedaling downwards through a rotational movement. At the same time it supports the hip side of the other leg. The driver is supported by the bicycle seat even in the upright riding position.

A foldable vehicle includes a front wheel frame having a front wheel pivotably connected thereto, the front wheel frame having a front circular opening for receiving the front wheel. The vehicle also has a rear wheel frame having a rear wheel pivotably connected thereto, the rear wheel frame having a rear circular opening for receiving the rear wheel. A pivot joint connects the front wheel frame and the rear wheel frame, with the front wheel frame and the rear wheel frame being pivotable against each other via the pivot joint. A front vertical support extends from the front wheel frame and has a handlebar assembly pivotably secured to the front vertical support, and a rear vertical support extends from the rear wheel frame and has a seat assembly removably secured to the rear vertical support.

The present invention provides a means for powered, programmable transformation of a bicycle to fit a given cyclist for a given condition while riding. It comprises a computer/app and actuators to perform all adjustments while riding, that is programmable to recall fit information and/or to follow a fit algorithm that will transform a bicycle to match a particular rider's best fit for a particular condition such as climbing, descending, sprinting, etc. It also may adjust fit in response to on-the-fly rider commands, sensor inputs, and/or data from other devices.
