An apparatus and a method for bicycle anti-theft are provided. When a biometric feature of a user matches a preset biological feature, a brake lever is fixed at a preset position to lock the bicycle.

Aspects of the disclosure relate to saddle type vehicles having at least one seat and at least two wheels, at least one electric motor, and a rechargeable electric energy storage system, such as a battery and battery management system. A vehicle seat may be mounted on an adjustable inner seat post, where the adjustable movement may be vertical, substantially vertical, or at least partially vertical. Vehicle handlebars may be mounted on an inner shaft which allows movement parallel to the steering axis and is indexed to an outer steering stem that allows the handlebars, a chassis fork and front wheel to be steered together. In some examples, the inner seat post and handlebar inner shaft are electronically raised and lowered, for example by one or more electrical stepper motors, such that position of handlebars and seat may be selected by rider.

A handle to be installed on an upper bracket that connects upper end sides of a pair of front forks is provided. The handle includes a handle bar and a handle holder. The handle bar includes a base portion installed on an upper surface of the upper bracket. The handle holder extends from a center of the upper surface of the upper bracket toward the pair of front forks. The base portion and the handle holder are fixed to the upper bracket by a fixing member.

The present disclosure provides a scooter. The scooter includes a scooter body and a photographing portion; the photographing portion is mounted on the scooter body; and the scooter body is provided with an avoidance space for avoiding a photographing view angle of the photographing portion, so that the photographing portion photographs a road condition around the scooter body.

Examples of the present disclosure relate to a bicycle configured to easily and efficiently adapt for riders of different sizes while providing both balance bike and pedal bike functionality. An exemplary bicycle is a children's bicycle designed and developed to grow with a child. An exemplary bicycle is configured to enable utility adjustments to a front assembly, among other components, which creates a setup that comfortably accommodates either smaller riders or larger-sized riders. The bicycle is adjustable with minimal effort and without tools, enabling re-configuration on the fly. Further disclosed is an exemplary training wheel device that is attachable to an exemplary bicycle. An exemplary training wheel device extends functionality of the bicycle and assist with training a young child to ride the bicycle.

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 leaning vehicle including a braking mechanism, a linkage mechanism configured to cause a body frame of the leaning vehicle to lean leftward or rightward, a lean lock mechanism configured to restrict leftward leaning and rightward leaning of the vehicle body frame, and an interlocking mechanism configured to actuate the braking mechanism and the lean lock mechanism. The interlocking mechanism includes an operation input section configured to input a first operating force, a brake-operation-input section configured to input a second operating force, an operating force distributor configured to distribute the first operating force input by the operation input section to the lean lock mechanism and the braking mechanism, and a brake actuator configured to actuate the braking mechanism by the first operating force distributed to the braking mechanism by the operating force distributor, or by the second operating force input by the brake-operation-input section.
