E-scooter conversion

The challenge

I wanted a practical way to get to the park without relying on a lift. Rather than buying an electric scooter, I set out to convert one myself. The project brought together mechanical work, battery assembly, electronics, and a lot of packaging decisions.

Making the hardware fit

The new hub-motor wheel was larger than the original wheel mount could accommodate, so we cut slots in the rear wheel holder to make room. The scooter’s battery compartment was long and narrow; I arranged the battery pack in three sections and soldered in a Battery Management System.

From wiring to a working build

I added a charging port to the side and worked on GPS tracking, an SOS function, a ring function, LED strip lighting, and a lock feature. Once the electronics were assembled, we packed the components underneath the scooter. My dad and I made a bottom cover from aluminium sheet, painted it grey, and added a rubber seal before fitting it.

What this project shows

This build documents how I approached a real need by working across software, electronics, and mechanical constraints. It was later invited to a showcase at Leaps of Knowledge 2022. The photographs and original build notes below record the development process.
