Product Overview
Restore smooth speed control and reliable power delivery with this 48V 1000W DC brushed motor speed controller, designed for compatible electric scooters, e-bikes, go-karts, tricycles, mini quads, and custom electric vehicle builds.
Built for 48V brushed DC motor systems, this controller helps manage throttle input, motor output, braking signal, and low-voltage battery protection. It is a practical replacement for failed or unstable controllers causing no throttle response, weak acceleration, intermittent power cut-off, poor speed control, or controller overheating.
The grooved aluminum alloy housing helps dissipate heat during operation, while the multi-harness wiring layout supports common scooter and e-bike functions such as power input, motor output, throttle, brake, and auxiliary control connections.

Fitment FAQ
Will this part fit my specific model and year?
This speed controller is intended for Electric Scooter, E-Bike & Go-Kart. Key physical/spec details from the product data include System Voltage: 48V, Low-Voltage Protection: 42V ± 0.5V (Standard Safeguard), 48V. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this speed controller, also compare the voltage, wattage/current rating, motor type, connector set, throttle/brake inputs, and battery compatibility.
What models or situations does this part not fit?
Do not order this speed controller for machines outside the listed compatibility, or for units with different voltages, wattage/current ratings, motor types, connector sets, or battery systems. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the voltage, wattage/current rating, motor type, connector set, throttle/brake inputs, and battery compatibility. Recheck listed specs such as System Voltage: 48V, Low-Voltage Protection: 42V ± 0.5V (Standard Safeguard), 48V. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
