Project Summary

This Custom Electric Scooter Conversion is a personal project that involves transforming a pre-existing mobility scooter chassis into a fully functional electric scooter. The project began with picking out a robust, lightweight chassis (sourced from a thrift store), which I modified to accommodate a high-efficiency VEVOR 2000W brushless DC motor and a 52V 20Ah lithium-ion battery pack. The motor was mounted securely and connected to the rear wheel for direct drive, while the battery was housed within the pre-existing lead-acid battery box for protection and easy access. I integrated a motor controller to regulate speed and power, implemented a throttle for smooth acceleration and deceleration, and added safety features such as an emergency cut-off switch and regenerative braking. To ensure efficient connections, I developed a wiring harness and installed a display to monitor speed, battery level, and other essential parameters.

Throughout the project, there were many, many challenges. Space constraints, heat management, water/snow resistance, and electrical interference were some of the big ones. The completed scooter achieved a top speed of ~35mph and a range of 25 miles per charge, showing surprisingly better-than-expected performance and reliability.
