SPIDER Automation | E-Bike Electric Brake Lever Set | Left & Right Aluminum Alloy Levers with Brake Cut-Off Switch
The SPIDER Automation E-Bike Electric Brake Lever Set combines conventional bicycle brake lever operation with an integrated electrical brake cut-off switch. When either lever is operated, the switch provides a brake signal to a compatible e-bike controller, allowing the controller to interrupt motor drive operation while braking.
The set includes left- and right-side aluminum alloy brake levers with pre-attached electrical cables. Designed for handlebars with a compatible 22.5mm mounting diameter, these levers are suitable for electric bicycle conversion projects, replacement installations and controller-based motor cut-off systems.
Technical Features & Functional Characteristics
- Integrated Electrical Brake Switch: Each lever incorporates a switch that provides an electrical brake signal when the lever is operated.
- Motor Drive Cut-Off Function: The brake signal allows a compatible controller to interrupt motor drive during braking.
- Left and Right Lever Pair: Supplied as a two-lever set for installation on both sides of the handlebar.
- Aluminum Alloy Lever Construction: Provides a rigid mechanical lever structure for bicycle braking operation.
- Pre-Attached Switch Cables: Electrical cables are supplied with the levers for connection to a compatible controller brake input.
- Non-Polarity-Sensitive Switch Wiring: The brake-switch connection does not require positive and negative polarity distinction, according to the supplied wiring description.
- Conversion and Replacement Use: Suitable for compatible e-bike builds and replacement of existing levers where the mechanical and electrical interfaces match.
Brake Cut-Off Function & Controller Integration
The integrated brake switch is intended to work with an electric bicycle controller that supports an electrical brake input. When the lever is squeezed, the switch changes its electrical state and sends the corresponding signal to the controller. The controller can then interrupt motor drive while the rider applies the brakes.
This function helps prevent continued motor assistance during braking. The actual response depends on the controller’s brake-input configuration and supported braking functions. Regenerative braking is only available when supported by the connected motor controller and drive system; it is not an independent function of the lever itself.
Handlebar Mounting & Mechanical Compatibility
The lever set is designed for handlebars with a compatible 22.5mm mounting diameter. It can be considered for mountain bikes, road bikes and other bicycle configurations when the handlebar dimensions and mechanical brake arrangement are suitable.
Before installation, ensure that the lever’s mechanical cable-pull arrangement matches the bicycle’s braking system. The electrical cut-off switch provides a controller signal; it does not replace the mechanical or hydraulic braking mechanism.

Connection & Operating Recommendations
For correct operation, the mechanical brake arrangement and electrical switch input must both be compatible with the bicycle and controller. Follow these recommendations during installation and connection.
- Confirm Handlebar Compatibility: Ensure that the handlebar mounting diameter matches the lever’s 22.5mm mounting specification.
- Match the Mechanical Brake System: Confirm that the lever’s mechanical actuation arrangement is suitable for the bicycle’s brake mechanism.
- Connect to the Brake Input: Connect the switch cable to the compatible electrical brake input on the e-bike controller.
- Observe the Switch Rating: Keep the connected switch circuit within the stated 0.5A at 60V workload rating.
- Check Switch Operation: Operate each lever and confirm that the controller responds correctly to the brake signal before riding.
- Secure the Cables: Route and secure the electrical cables away from moving parts, sharp edges and areas where steering movement could pull or damage them.
- Test Mechanical Braking: Confirm that both brakes engage and release correctly. The electrical cut-off switch is an additional controller signal, not a substitute for the braking mechanism.
- Check Regenerative Braking Support: Do not assume regenerative braking is available; it depends on the connected controller and motor system.
