An electric transformable scooter that can transform between a stand-on configuration and a ride-on configuration. The scooter has a fixed frame member at the front to which the front wheel and handlebar are mounted, and movable frame member that extends between the rear wheel and the fixed frame member. The front end of the movable frame member slides or otherwise adjusts to either a lower position or an upper position on the fixed frame member. When the movable frame member is at the lower position and locked thereat, it is generally horizontal, and its top surface defines a stand-on floorboard for stand-on operation. When the movable frame member is slid to its upper position and locked thereat, it is inclined from front to rear, and portion rotates away and locks thereat to become a seat for ride-on operation.

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 traveling apparatus includes: an operation member configured to be displaced to a first range and a second range; an adjusting mechanism configured to adjust a wheel base length between a front wheel and a rear wheel in such a way that the wheel base length is increased when the user displaces the operation member in a direction away from a reference position in the first range; and a controller configured to control, when the user manipulates the operation member in the first range, a driving unit in such a way that the traveling apparatus travels forward based on a forward movement target speed that has been made to become larger as the wheel base length increases, in which the controller controls the driving unit in such a way that the traveling apparatus travels backward when the user manipulates the operation member in the second range.

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.

The invention relates to a tightening and adjusting assembly for a steering system of a bicycle. The steering system generally includes a head tube, a steering tube rotatably mounted within the head tube by means of upper and lower headsets, and a handlebar stem tube mounted around the steering tube. The tightening and adjusting assembly has a preload member, an anchoring member and a tightening and adjusting set. The preload member is engaged with a top end of the handlebar stem tube. The anchoring member is abutted against a bottom end of the steering tube. The tightening and adjusting set is disposed in the interior of the steering tube and between the preload member and the anchoring member to draw the preload and anchoring members together and thus preload the upper and lower headsets of the steering system.
