Why does the electric tricycle not move when the throttle is applied?

There are many reasons why an electric tricycle has power but does not move. Common causes include the following: issues with the handlebar, problems with the brake switch, malfunctioning controller, or problems with the motor. First, check if the brake switch has poor contact, then inspect the handlebar, and finally, look for any broken wires. If none of these are the issue, the controller may be damaged. Testing methods: Check the battery output of the electric vehicle to ensure it is normal. If the output is low, it confirms the battery is damaged and needs urgent replacement. Disconnect the brake cable: If the vehicle malfunctions, the brake handle must be replaced or repaired. Inspect the throttle handle: Use a wire to short the throttle handle and signal wire. If the car moves, it proves the throttle handle is damaged and requires immediate replacement or repair.
The other day I helped my neighbor check out his electric tricycle, and there were quite a few issues with it not moving when throttling. First, check the most obvious things: Are the battery terminals loose? Oxidized and greenish wire ends can also cause power loss. Is the battery charge sufficient? A voltmeter will tell you. Then inspect the throttle handle—if the Hall sensor inside is broken, the throttle signal won’t transmit. A stuck brake cutoff switch can also make the vehicle think you’re braking, triggering the controller’s automatic power-off protection. Loose motor wires or water-induced short circuits are even worse; if the motor feels hot to the touch, chances are the coils are burnt. A blown fuse in the controller is the most common issue—if the heat sink is scalding, replace it immediately. Oh, and last time, one trike’s wheel was tangled with a rope—it wouldn’t even move when pushed!
