Tim Gunn is a bicycle restorer known for his appearances on The Repair Shop, a British television programme that restores sentimental heirlooms. The show first aired in 2017 and is broadcast on BBC One (after initially airing on BBC Two).

He appears as a guest and semi-regular expert, specializing in the restoration of vintage bicycles and mechanical items. His work often involves repairing historically significant or sentimental bikes, including wartime and family-owned pieces.

Gunn has been featured in multiple episodes of the series from around 2019 onward, working alongside other craftspeople to bring meaningful objects back to life. His role typically focuses on complex mechanical restorations requiring specialist knowledge of historic bicycles.

Despite his television appearances, very little public information is available about his personal life. His date of birth, parents, and early background have not been disclosed in reliable sources.

He remains a relatively low-profile expert, appearing on the programme when items related to his specialization are brought into the workshop.
