The present invention discloses a self-balancing scooter, including a scooter body, wheels, a driving motor, a power supply, a circuit board provided with a sensor, a controller and a light emitting lamp. The controller is electrically connected to the circuit board, the power supply and the driving motor respectively. The scooter body includes: an upper shell, pedals, a middle shell, a lower shell and a lampshade. The middle shell is located between the upper shell and the lower shell. The lampshade is provided with at least two spaced lamp strips for transmitting light. The scooter body is provided with lamp holes for placing the lamp strips. A quantity of the lamp holes is identical with a quantity of the lamp strips. Waterproof rings are sleeved on the lamps strips.

Disclosed is a loudspeaker box for bicycle, which includes a housing provided thereon with an illumination unit, a key unit, a loudspeaker, a memory card interface, and a charging and discharging connector, and provided therein with a circuit board and a battery. The circuit board includes a main control unit, a power amplifier unit, and a charging and discharging module which includes a charging and discharging chip, and a charging end of the charging and discharging chip is electrically connected to the drain of a first MOS tube; the source of the first MOS tube is electrically connected to a voltage end of a charging and discharging connector; a discharging end of the charging and discharging chip is electrically connected to the drain of the second MOS tube; and the source of the second MOS tube is electrically connected to the voltage end of the charging and discharging connector.

An intelligent follow-up illumination device includes a support component, a rotating component, a driving component, a light source component, a projection component, a control component, and a casing. The support component is adapted to be installed on a vehicle in a fixed state. The rotating component is disposed to rotate relative to the support component. The driving component is disposed between the support component and the rotating component to drive the rotating component to perform a rotation operation around a rotation axis. The light source component is disposed inside the rotating component to emit illumination light. The projection component is retained on the rotating component to project the illumination light outwardly, so as to form a light distribution pattern. The control component is connected to the rotating component and adapted to send a control command to the driving component. The casing is disposed to enclose the control component.

A bicycle tail light or front light has a mounting base to connect to the bicycle, and an LED light unit for insertion into and removal from the base. The light unit includes a printed circuit board with LED driver and a rechargeable battery, all of which are encapsulated by a direct overmolding that forms a casing for the unit. For charging the light unit is pulled out from the base and plugged into a USB port. A tongue with USB blade at the back of the light unit functions to secure the light unit to the mounting base, and the attachment of the units switches power to the light unit. A motion detector on the PCB shuts off the LED if no motion is detected for several minutes, thus eliminating need for any exterior switch.

A method for prompting bicycle gear shifting includes collecting cycling data of a user during cycling, comparing the collected cycling data with cycling data samples in a preset gear shifting strategy library including correspondence relationships between preset gear shifting strategies and the cycling data samples, and when the collected cycling data matches one of the cycling data samples in the gear shifting strategy library, outputting the gear shifting strategy corresponding to the cycling data sample to the user.

A dual bicycle headlight and taillight of a compact and lightweight configuration can be mounted on a bicycle handlebars as a headlight to project white light from a white light emitting diode and, alternatively, mounted on a rear of a bicycle as a taillight to project red light from a red light emitting diode. The projected light in both modes of a headlight or a taillight will be parallel to a support surface that the bicycle will traverse. A single flexible mounting strap is rotatably attached to a common light housing to provide a secure mounting of the headlight and taillight modes of operation by the same light housing.

A snowmobile including a warming element at a handlebar of the snowmobile. The warming element is configured to generate heat in response to electrical current driven therethrough. A user interface is configured to receive inputs from an operator of the snowmobile. The inputs include a first temperature input setting a first predetermined temperature for the warming element. A control assembly includes a warmer control button configured for setting the warming element at the first predetermined temperature. A control module is included with the control assembly and in receipt of inputs from the user interface and the control assembly. The control module is configured to, when the first predetermined temperature is selected by way of the warmer control button, direct sufficient electrical current to the warming element to generate heat equal to the first predetermined temperature.
