City Bike Frame Kit – Bamboo
Upright, comfortable geometry with mounts for racks, mudguards and lights — hand-built by you from fast-growing bamboo and flax instead of carbon. A bike that turns heads at the rack, soaks up potholes, and carries a sustainability and social story no off-the-shelf frame can match.

you can't really ruin it
The glue is slow and adjustable, each joint wrap is additive (more = stronger), and a cured joint simply sands back to shape. The kit even ships with spare bamboo — at no single point is a mistake permanent.

caring for your frame
Seal the bamboo and store it indoors; dry it after wet rides. A frame you built — and understand — is one you can maintain and repair yourself for years.

Going to the workshop was hands-down one of the best things I have ever done.
Stuart Heritage · The Guardian
rated by the builders who made one
It rides great and it's so comfortable — the only problem is everyone who sees it wants to talk about it or have a go.
Karl · single-speed city build, MedwayTo see the bike the first time and sit on it was euphoria. I was more taken than when I got my new car (sorry, car).
Tamas · belt-drive city buildbefore you build.
Can I really ride it in the rain every day?
Yes. Finished frames are sealed with a weatherproof epoxy lacquer. Dry your bike after wet rides, store it indoors and check the joints regularly.
How much maintenance does a bamboo commuter need?
Very little. Build it single-speed and there's almost nothing to service — no derailleur to adjust. Keep the chain clean, dry the frame after wet rides, and inspect the joints once a year. That's it.
Will it handle hills and city traffic?
The frame is single-speed or hub-gear ready, so you can spec gearing to suit your route and hills. The upright geometry gives you excellent visibility in traffic, and it fits standard racks, mudguards and lights.
Is it strong and secure enough for daily city use?
Can I get it through Cycle to Work?
Yes. Our frame kits are eligible for standard Cycle to Work schemes — UK employees typically save 25–39% through salary sacrifice. We accept Cyclescheme, Cycle Solutions, Evans and Halfords.
