Fully custom bikes, racks and stems.

Handmade from steel, in Bristol.

My name is Pi Manson.

From my workshop in Bristol, I make beautiful and functional bikes and components from steel. I build mountain bikes for the future with Starling Cycles, and ride coaster brake clunkers from the past.

My custom components have featured on award winning show bikes, been ragged by hard working messengers, and abused on long bike tours. My bikes are strong, fit for purpose, utilitarian, award winning.

I write for Boneshaker Magazine, and ran the inaugural Fringe for the Bespoked handmade bike show: Besmirched.

I believe in:

DIY punk, fun bikes, and truth to materials.

I want local, handmade bikes and parts to be as accessible as possible.

I leave my fillets un-filed. They show the process, the maker’s marks.

A raw fillet is honest and utilitarian, beautiful as it is.

Email me, and we can arrange for you to stop by the workshop, talk about what you want over a cuppa, and get your custom bike or component underway.
