What Causes an Electric Tricycle to Move Forward Instead of Reverse?
2 Answers
It may be that the reverse switch on the vehicle's handle is broken, causing it to remain in reverse mode, or the reverse signal wire may be damaged. Below is related information about electric tricycles: Electric Tricycle (Electrically operated tricycle): It is a three-wheeled transport vehicle powered by batteries and driven by a motor, used for carrying goods or passengers. Batteries used in electric tricycles: Electric tricycles use tubular, high-capacity, deep-discharge, traction-type batteries with left and right liners, which can meet the requirements of continuous discharge for long working hours. Under normal use, the battery lasts for two years without losing capacity. The motor of an electric tricycle uses a DC series-wound traction-type brushed or brushless motor, equipped with a speed-regulating and power-increasing device inside. It is not easily damaged under normal use, ensuring strong power output.
A few days ago, my neighbor's vegetable-hauling tricycle had the same issue, and I took a look. The most common cause is the aging or displacement of the contact plates inside the forward/reverse switch—this thing gets constantly flipped back and forth and is prone to wear. Another possibility is that the logic chip in the controller got jostled loose, especially in vehicles that have been exposed to rain. For wiring, focus on checking the cables connected to the forward/reverse switch to see if any insulation is worn and causing a short. The weirdest case I encountered was a faulty Hall sensor in the throttle grip, where erratic signals turned forward commands into reverse. Fixing it isn’t too hard—start by replacing the forward/reverse switch; it’s just a ten-dollar part.
