This video provides a comprehensive walkthrough of wiring and setting up an electric bike conversion using a QS138 70h v3 motor and a VOTOL EM200 controller. The creator demonstrates the detailed process of connecting various components, including the motor, controller, battery, and additional accessories like a DC-to-DC converter. Key technical details include the motor’s power capabilities (3000 watts, potentially upgradable to 17-25 kilowatts), and the controller’s impressive 200-amp capacity. The tutorial covers critical wiring steps such as connecting phase wires (blue, green, yellow), setting up the power switch, connecting hall sensors, and configuring speed control options. The presenter explains how to wire the battery, motor, throttle, and additional components like the USB programming port and speed control switches. The video is particularly valuable for electric bike enthusiasts and DIY builders looking for a practical, step-by-step guide to complex e-bike electrical system installation, addressing the lack of comprehensive online resources for this specific motor and controller setup.
