SPIDER Automation | 12–72V E-Bike Throttle with Integrated Power Switch | 22mm Handlebar Mount
The SPIDER Automation Power Switch with Throttle is a combined handlebar control assembly designed for electric bicycles and compatible electric vehicles. It integrates a manually operated throttle with a power ON/OFF switch, allowing the rider to control motor demand and operate the connected power-switching circuit through a compact handlebar-mounted unit.
The assembly is specified for 12–72V electric vehicle systems and features a 22mm handlebar mounting diameter. Its throttle uses a three-wire electrical interface with red for supply, black for ground and white for signal output. The switch section is supplied with a 60cm cable, while the separately listed brake-section cable length is 130cm.
Product Overview & Operating Principle
Electric vehicles can use different methods to request motor operation. In a throttle-controlled system, the rider manually operates a handlebar throttle to provide a speed-demand signal to the motor controller. The controller interprets this input and regulates motor operation according to its own control logic and system configuration.
This product combines that throttle function with a power ON/OFF switch in one assembly. The throttle provides the rider’s manual control input, while the integrated switch operates the connected power-switching circuit. The actual circuit controlled by the switch depends on the vehicle’s wiring arrangement.
Technical Features & Functional Characteristics
- Combined Control Assembly: Integrates a throttle and power switch into one handlebar-mounted unit for convenient vehicle control.
- Wide System Voltage Range: Specified for 12–72V electric vehicle systems, supporting a range of compatible e-bike and electric mobility configurations.
- Manual Throttle Operation: Provides a rider-operated input for requesting motor speed through a compatible motor controller.
- Integrated Power Switching: Includes an ON/OFF switch for controlling the connected power circuit as configured during installation.
- Three-Wire Electrical Interface: Uses separate supply, ground and signal connections for the throttle section.
- Standard Handlebar Mounting Size: Features a 22mm inner mounting diameter for compatible handlebar installations.
- Separate Cable Sections: Includes a 60cm cable for the switch section and a separately listed 130cm cable for the brake section.
- Multi-Vehicle Design: Intended for compatible electric bicycles, scooters, motorcycles, ATVs, tricycles and electric rickshaw-type vehicles.
Throttle Operation & Motor Controller Interface
The throttle operates as a manual control input for a compatible electric motor controller. When the rider moves the throttle, it provides a corresponding signal to the controller, which processes the input and adjusts motor operation according to its supported throttle interface.
The throttle’s three-wire connection separates the supply, ground and signal paths. Correct wiring is essential because the throttle signal must be compatible with the controller’s input requirements. The throttle should therefore be matched with the controller’s voltage and signal specifications rather than assumed to work with every controller.
Integrated Power ON/OFF Switch
The integrated power switch provides a convenient handlebar-accessible switching function alongside the throttle. It can be incorporated into the vehicle’s designated power-control circuit, allowing the rider to operate the connected circuit without installing a separate switch at another handlebar position.
The switch must be connected according to the vehicle’s electrical design and the switch’s contact rating. The specified 12–72V system range should not be interpreted as a confirmed current rating or proof that the switch can directly interrupt every motor or battery current. High-current motor power circuits require switching components rated for the actual electrical load.
Wire Configuration & Connection Details
The throttle section uses a three-wire connection. The supplier identifies the wire functions as follows:
| Wire Colour | Connection Function |
|---|---|
| Red | Supply |
| Black | Ground (GND) |
| White | Throttle Signal |
Connect the throttle wires to the corresponding controller terminals after confirming the controller’s supply voltage, ground reference and throttle signal requirements. The switch and brake-section wiring should be integrated according to the vehicle’s wiring diagram; the three-wire throttle configuration above does not define the switch or brake-section pinout.
Mounting & Mechanical Installation
The assembly is designed for handlebar mounting with a specified 22mm inner diameter. Before installation, ensure that the handlebar diameter and available mounting space are suitable for the assembly. Position the throttle so that it can be operated comfortably without obstructing the brake lever or other handlebar controls.
Applications
The integrated throttle and power-switch arrangement can be used in electric vehicles that support a compatible handlebar throttle input and switching configuration.

Installation & Operating Recommendations
For reliable operation, the throttle, power switch and vehicle controller should be electrically compatible and installed according to the vehicle’s wiring configuration. The following points help support correct integration:
- Confirm System Voltage: Ensure that the vehicle’s electrical system is within the specified 12–72V range and that the throttle supply connection is compatible with the controller’s designated throttle supply.
- Match the Throttle Signal: Check that the controller accepts the throttle signal type and operating range provided by the throttle before connecting it.
- Follow Wire Identification: Connect red to the designated supply, black to GND and white to the throttle signal input, following the controller’s wiring documentation.
- Wire the Power Switch Correctly: Integrate the switch into the intended control or power-switching circuit according to its electrical rating and the vehicle’s wiring diagram.
- Check the Brake Section: Identify the brake-section wiring and its intended circuit before connection. Do not infer its pinout from the throttle’s three-wire configuration.
- Check Handlebar Fitment: Confirm the 22mm mounting diameter and position the assembly so that the throttle moves freely without interfering with other controls.
- Secure the Cables: Route the cables away from moving parts, sharp edges and hot surfaces, allowing enough slack for normal handlebar movement.
- Test Before Riding: With the vehicle safely supported, check throttle response and switch operation before normal use.
