What is the E-Bike Wiring Diagram Helper?

It is an interactive tool that visually maps standard wiring connections for e-bike components, including motors, controllers, batteries, throttles, brakes, sensors, and lights.

Which e-bike components does it cover?

The tool includes Standard BLDC Motors, PMSM Motors, generic Chinese and Kelly controllers, throttles, brake cutoffs, Hall sensors, displays, BMS, and batteries.

Can I use this tool for my DIY build?

Yes, it provides standard wiring references, but always verify your specific components and manufacturer manuals before applying power.

Does it show Hall sensor and throttle wiring?

Yes, the tool clearly identifies Hall sensor wires (power, ground, signal) and standard 0-5V throttle wiring for supported controllers.

Can I export or save my wiring diagrams?

Absolutely — you can export diagrams as PNG or PDF, save and load JSON files, or embed the diagram on your own website.

Yes, RideWattly provides the Wiring Diagram Helper free for DIY enthusiasts, repair technicians, and hobbyists.

Can I interact with the components directly?

Yes, you can drag components, hover over connections for info, undo/redo actions, and dynamically build your wiring layout.

What is the difference between BLDC and PMSM motor wiring?

BLDC motors usually have 3 phase wires (Yellow, Green, Blue) and Hall sensors, while PMSM motors may have additional feedback wires for precise rotor position control.

How do I test Hall sensors safely?

Use a 5V supply for Hall power, check continuity to ground, and verify signal pulses with a multimeter or oscilloscope while rotating the motor shaft slowly.

Can I swap phase wires if the motor spins backward?

Yes, swapping any two phase wires (Yellow/Green/Blue) reverses rotation direction without affecting performance.

How do I identify throttle signal and ground wires?

Typically, White is the throttle signal (0-5V), and Black is ground. Always verify with a multimeter before connecting to the controller.

What is a brake cutoff wire and how does it work?

The brake cutoff wire (often Red/White) connects to a brake lever switch; it cuts motor power when brakes are applied to ensure safety.

How do I wire PAS sensors correctly?

Connect the PAS signal wire (Green) to the designated controller input, power the sensor properly, and ensure the magnet disc aligns with the sensor.

What if my motor has extra wires not shown in the tool?

Extra wires may be for temperature sensors, encoders, or advanced features. Check the manufacturer’s manual before connecting.

How do I avoid damaging the controller when testing wiring?

Double-check all wire colors, ensure proper polarity, use fuses, and power on briefly while monitoring voltage and current carefully.

Can this tool help with e-bike repair troubleshooting?

Yes, it helps identify wire functions visually, making it easier to detect miswiring, sensor faults, or disconnected phase wires.

Can this tool be used with non-standard or custom controllers?

While primarily for standard controllers, the visual color references can guide you for similar models. Always measure voltages and verify connections before applying power.
