Apprenticeship Final Project – Electric Scooter

Jun 1, 2022 min read

Built an electric scooter from scratch — started as a vocational school project and developed well beyond that. In the final year of the polymechanics apprenticeship, a team of six students began the build together; after graduation, it was completed independently and continuously optimised.

Construction

The frame was built as a welded structure, while the handlebar components were CNC-turned from stainless steel. 3D printing was used to cleanly integrate the electronics into the frame.

Drive & Electronics

The first version with a separate motor and belt drive proved impractical and was replaced with a compact hub motor. Motor control is handled by VESC — a powerful open-source motor controller.

Further Development

Over time, 3D-printed mudguards were added along with a fully custom-built battery pack with BMS.
