A smart bicycle includes various integrated electrical accessories. The bicycle frame has an integrated computer processor, a global positioning system (GPS) receiver, horn and rear light. The stem of the bicycle has an integrated visual display that provides performance and directional information to the user. The fork of the bicycle has integrated lights and the front wheel can have an integrated dynamo generator that can power the electrical components and charge a system battery. The ride data can be transmitted to a smartphone and/or system servers, which can also store, analyze and display the rider data.

A charge system and a charge method adapted to a bicycle are provided. The charge system includes a hub dynamo, a power apparatus, a sensor and a control apparatus. The control apparatus is coupled to the hub dynamo, the power apparatus and the sensor. The sensor is adapted to sense a riding condition of the bicycle. According to the riding condition, the control apparatus selects a power supply pattern of the hub dynamo. When the power supply pattern is selected to be a stop pattern, a connection loop between the hub dynamo and the power apparatus is turned off by the control apparatus. When the power supply pattern is selected to a first pattern, the connection loop between the hub dynamo and the power apparatus is turned on by the control apparatus, such that the hub dynamo supplies power to the power apparatus at a first rate.

A green bike comprises a frame, two wheels, a first internal-gear module and a second internal-gear module and a transmission element. The frame has a pedal, a front supporting unit, a rear supporting unit, and a seat unit. The two wheels are attached to the front supporting unit and the rear supporting unit, respectively. The transmission element is disposed in the frame or a tube shield linking to the frame. The first internal-gear module and the second internal-gear module are coupled with the pedal and at least one of the wheels. The transmission element links the first and the second internal-gear modules for delivering power to the at least one of the wheels.

A bicycle braking system includes a server, a portable device such as a smartphone, a display unit, a control unit, a power supply unit, a rotating electrical machine, and a bicycle. The portable device includes an image display unit, a braking condition transmitting unit, and a braking condition setting unit. The control unit regeneratively brakes the bicycle using the rotating electrical machine in accordance with the braking condition set by the braking condition setting unit. The braking system enables a non-user to set braking conditions for the bicycle and to perform braking based on the conditions set by the non-user.

Wheel for a bicycle, particularly a balance bicycle, the wheel is provided with integrated lighting and an integrated electromagnetic power source which provides the lighting with power as soon as the wheel is driven when riding the bicycle.

A wheel unit includes a rotating wheel, a wheel axle, and a location sensor. The rotating wheel rotates with respect to the wheel axle. The location sensor is disposed in a fixed position with respect to the wheel axle. The location sensor determines coordinates for a location of the wheel unit.

The disclosure relates to the field of cycle technologies, and particularly to a wheel and a cycle. The wheel comprises a rim, a tire covering an outer periphery face of the rim, and a friction power device sandwiched between the rim and the tire; wherein the friction power device can produce a frictional current when pressed by the rim and/or the tire.
