An electro-mechanical gyro-balanced unicycle includes a wheel provided with a first motor, a housing provided outside the wheel and hollow pedals respectively provided at both sides of the housing. The pedal is provided with an electro-mechanical gyro assembly, and the electro-mechanical gyro assembly includes a second motor and a rotor capable of being driven by the second motor to rotate at a high speed so as to produce torques in a horizontal plane. The unicycle has a simple structure, can enable a beginner to be capable of quickly getting on the unicycle without any external assistant force, and can still well realize self-balance in left and right directions over time.

A three wheeled stand-up or sit down foldable and portable electric personal mobility vehicle for fulfilling the needs of a broad spectrum of users including the handicapped and recreational users. The personal mobility vehicle has two major parts, including a front wheel frame assembly and a rear frame chassis assembly. These major parts are configured to easily fold into a smaller size so that the vehicle can be easily transportable and more conveniently stored. Furthermore, a versatile seat and seat post are implemented to enable a user to sit or stand, and the seat can be easily removed, without tools, to create more space should a user wish.

A foldable structure of an electric vehicle is disclosed. In the foldable structure, a frame defines a stowing space, and includes a connection base and a rotatable seat. The connection base has a chute and the seat includes a link rod. The wheel part includes two wheel casings, a tire and a driving device, and a containing space is formed between the wheel casings for containing the tire and the driving device. The wheel casings has a rotator cap protruded at tops thereof, and the rotator cap has an axle hole longitudinally cut therethrough, and the rotator cap is pivotally connected with the rotatable seat by the axle hole, whereby the link rod can be slid into the chute, and the two wheel casings and the tire can be laterally rotated into the stowing space, such that the electric vehicle can just occupy smaller space.

A two-wheel, self-balancing vehicle is disclosed. In one aspect, the two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, the first wheel and the second wheel being spaced apart and substantially parallel to one another. The two-wheel, self-balancing vehicle further comprises a foot placement section connecting the first wheel and the second wheel. The two-wheel, self-balancing vehicle further comprises a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle. The two-wheel, self-balancing vehicle further comprises a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

The present invention relates to an electric motorcycle realized so that it can be subjected to a simple maintenance process. Such motorcycle is realized so that all the components at major risk of failure or deterioration are grouped in an unique compact and easily removable block called “block of electric components”. Moreover, the structure of the same motorcycle is conceived so that the extraction of said “block of electric components”, even if it is bulky and heavy, results simple and that it is also reduced at minimum the risk that such operation occurs in an incorrect way, or that it can provide other kinds of damage. All this aims at making the motorcycle maintenance and the restoration of its full function possible also at not specialized sites.
