Key Features
- Steady Speed Management: Provides a consistent power output to the motor, allowing for linear acceleration and stable cruising speeds without surging.
- Sensitive Braking & Control: Engineered for high responsiveness, ensuring that braking signals and direction changes are executed instantly for a safer riding experience.
- Advanced Thermal Protection: The high-quality aluminum shell acts as a heat sink, effectively dissipating heat away from the internal logic board to prevent thermal overload during extended use.
- Battery Safeguard: Features built-in Under-Voltage Protection (20V), which automatically cuts power if the battery level drops too low, preventing deep-cycle damage and extending your battery's lifespan.
- Compact & Durable: The strong, corrosion-resistant aluminum housing protects the internal circuitry from vibration and impact, making it ideal for the rough-and-tumble use of kids' scooters or off-road e-bikes.

Fitment FAQ
Will this part fit my specific model and year?
This speed controller is intended for Electric Scooter, E-Bike & Tricycle. Key physical/spec details from the product data include Voltage: 24V, Under-Voltage Protection: 20V ± 0.5V, 24V. 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 Voltage: 24V, Under-Voltage Protection: 20V ± 0.5V, 24V. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Incredible value - you can replace your hot wheels or Weelye controller with this, but needs some mods (remote won’t work).So my son grew out of his 12V ride in car (with remote). So I upgraded the motors to 24V, and used a step down so the music radio and lights would still work.The binary accelerator pedal on those cars are terrible, so I bought this (with a variable 1-4V speed accelerator pedal) and moved the binary pedal to be the brake.The important part is that this brake input only cuts power to the motors. It doesn’t short the motors creating back EMF to actually “brake” the wheels.It was pretty easy to add a 40A car relay that is triggered from the brake light to achieve the full brake effect without the need for mechanical brake. The relay had a natural very tiny delay so now using the brake pedal would cut power to the motors AND short the motors which brakes the wheels.
