1. Power-assisted mode on the left handlebar: Electric bicycles usually have three power-assisted modes, including no power-assisted mode, low power-assisted mode and high power-assisted mode. The power-assisted mode switch on the left handlebar is used to switch the power-assisted mode of the bicycle. When the button on the left handlebar is turned off, it means that the electric bicycle is in the non-power-assisted mode and needs to ride completely by human power. When the button on the left handlebar is turned on, it means that the electric bicycle is in a low-power mode or a high-power mode, and a better riding experience and effect can be obtained through the auxiliary drive of the motor.
2. Gear on the left handlebar: Electric bicycles usually have multiple gears to control the output power and speed of the motor. The gear adjuster on the left handlebar is used to switch the gear of the electric bicycle. When the button on the left handlebar is in the second gear, it means that the electric bicycle is in the second gear, and the motor output power and speed are high, so it is suitable for driving on flat roads. When the button on the left handlebar is in the 1 position, it means that the electric bicycle is in the first position, and the output power and speed of the motor are low, so it is suitable for driving when climbing or the road is uneven.
