PLEASE NOTE: The below relates to Hampton Wick only.
During this bike mechanic course, our mechanic will guide you through everything you need to know about building the confidence to perform minor repairs at home and address roadside mechanicals that you may encounter.
The purpose of this mechanic course is for the participant to develop the skills and learn how to use the tools needed to make these types of repairs. Where possible, we aim to use tools that you can purchase yourself in-store and avoid relying on workshop tooling that can cost hundreds of pounds.
