An electric balance bike comprising:
- a bike frame comprising a seat at an intermediate position thereof, a head tube at a front end thereof, and a rear fork at a rear end thereof;
- a front fork connected to a lower end of the head tube;
- a handlebar connected to the head tube, the handlebar configured to control rotation of the front fork;
- a front wheel connected to the front fork;
- a rear wheel connected to the rear fork;
- an actuating assembly arranged between the bike frame and the rear wheel, the actuating assembly comprising an actuator located below an intermediate section of the bike frame, a driving member located at an axle of the rear wheel, and a driving belt that is wrapped around the actuator and the driving member;
- a battery detachably connected to the actuating assembly;
- and
- a controller comprising, a power abnormality response system;
- the power abnormality response system comprising a determination component, detection components, and a warning component, the determination component being respectively connected to the detection components and the warning component, the detection components respectively detecting running statuses of the actuator and the battery and outputting detection values, the determination component receiving the detection values and determining whether the detection values are abnormal or not to output different control signals to drive the warning component to respectively send out different warning signals;
- and wherein
- the detection components comprise voltage feedback circuits and current feedback circuits, the battery is connected to the voltage feedback circuits, so that a voltage of the battery is detected to confirm an electric quantity of the battery;
- and the actuator is connected to the current feedback circuits, so that a current of the actuator is detected;
- and wherein the warning component is a buzzer, and when the determination component determines that corresponding detection values obtained through detecting the battery by the current feedback circuits are lower than a normal value, a voltage of the battery is determined to be too low, so that a control signal is sent out for warning that battery power is insufficient, and the warning component sends out a sound warning signal with one long and two short sound;
- and wherein
- when the determination component determines that the corresponding detection values obtained through detecting the battery by the current feedback circuits are different from the normal value, the actuator is determined to be over-current, so that a control signal is sent out for warning that the actuator is over current, and the warning component sends out a sound warning signal with one long and three short sound.
