The scooter slowed down seriously when it released the accelerator.

Loosen the throttle, resulting in a decrease in engine speed, resulting in a decrease in wheel speed, resulting in deceleration.

The throttle of motorcycle is the rotating shaft of control steel wire. Turning the throttle is equivalent to winding the steel wire around the shaft, so the throttle of the carburetor is pulled to rotate, and the engine speed increases with the increase of the passing air. This is such a principle.

Throttle, also known as "throttle" and "throttle". Refers to the control device that controls the engine power (thrust). On the piston aero-engine, the throttle valve controls the opening of the carburetor to control the filling amount of the cylinder, thus determining the output power of the engine. On the gas turbine engine, the throttle valve controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine.

The position of the throttle is controlled by the driver operating the throttle lever in the cockpit, and it is transmitted to the carburetor or fuel regulator on the engine through control system components such as pull rod, rocker arm, torsion tube, steel cable, pulley and sector wheel. On an airplane, the throttle lever is always pushed forward to increase power (thrust) and pulled back to decrease power (thrust).

Scooters are basically stepless speed change automatic clutches, which are similar to Mulan electric vehicles. No gear design. After starting, they just need to twist the throttle and leave. When the throttle is turned off, they will automatically slow down gradually until they stop. Moreover, the wheels of scooters are smaller than other cars, and most of the transmission parts are belt transmission, which is also commonly known as women's motorcycles.
