Universal 3-Wire Thumb Throttle – Precision Speed Control for 24V to 72V Electric Systems
Whether you are replacing a damaged throttle or upgrading for smoother, more precise speed control, this universal 3-wire thumb throttle is the perfect solution. Designed to work seamlessly with electric scooters and e-bikes ranging from 24V to 72V, it connects directly without the need for complex modifications. The generous 160 cm cable provides plenty of length for routing along larger frames, and the standard colour-coded wiring ensures a straightforward installation process.
Note: Please verify the pin configuration on your controller before connecting, as some controllers may differ from the standard Red/Black/Green wiring sequence.
Why choose this throttle? (Key Benefits):
- Wide Voltage Compatibility — Works with 24V, 36V, 48V, 60V, and 72V systems, eliminating the need to hunt for a model-specific part.
- 160 cm Cable — Extra-long reach, perfect for larger frames or complex cable routing without requiring extensions.
- Contactless Hall Sensor — Delivers a smooth, consistent signal without the mechanical wear associated with traditional resistive potentiometers.
- Standard Colour Coding — Red (+5V), Black (GND), Green (Signal): simple, intuitive wiring for a quick 5-minute setup.
- Fits 22mm Handlebars — Compatible with the industry-standard diameter for most electric scooters and bikes, ensuring a secure fit with the included clamp.
- Thumb-Actuated Design — Provides fine-tuned speed control in urban traffic while maintaining a firm grip on the handlebars.
Performance and Specifications
The throttle signal is transmitted via a Hall sensor, ensuring a smooth, linear response without dead zones or jerky acceleration. The 160 cm cable is encased in an abrasion-resistant sleeve, designed to withstand friction against the frame over thousands of kilometres. The 3-pin connector follows the universal standard recognised by the vast majority of controllers on the market, including those found on popular e-mobility brands and aftermarket components.

Installation Guide
- Identify the existing wires on your vehicle: +5V power, ground (GND), and throttle signal.
- Match the wires to the standard colour scheme: Red → +5V, Black → GND, Green → Signal.
- If your controller’s pinout differs, rearrange the pins in the connector housing before plugging it in — do not force the connector if it does not fit.
- Mount the throttle onto the handlebar using the included clamp. Tighten securely, taking care not to over-tighten or deform the housing.
- Perform a test at low voltage or with the wheel off the ground to verify signal linearity and throttle response before your first ride.

Frequently Asked Questions
Is this compatible with my 48V scooter?
Yes. This throttle supports 24V, 36V, 48V, 60V, and 72V systems, so it is fully compatible with 48V setups.
How do I know if my controller pinout is compatible?
The standard wiring is Red (+5V), Black (GND), and Green (Signal). If your controller uses a different sequence, you can simply rearrange the wires within the connector block without needing to cut or solder.
Will this fit a 25mm handlebar?
The included clamp is designed for standard 22mm handlebars. It will not provide a secure fit on 25mm bars without a custom adapter or shimming.
Does this include a battery LED indicator?
No. This is a dedicated thumb throttle without an integrated display or battery gauge. If you require an integrated display, please look for 5-wire models or separate LCD units.
