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.

The material provides natural suspension.

rated by the builders who made one
It's very smooth, and it has some kind of suspension due to the very low tyre pressure of 0.5 bar.
Christopher · custom bamboo fatbikebefore you build.
What tyre sizes will it fit?
Designed for 26×4" or 27.5×4" fat tyres, with massive clearance for sand, snow and soft ground. Planning an unusual tyre setup? Ask us and we'll confirm the exact maximum clearance before you order.
What terrain is a fatbike actually for?
Soft, loose and slippery ground — dry sand, packed snow, mud, beach and bog. The very wide tyres run at low pressure so your weight spreads out and floats over the surface instead of sinking into it. They're also a confidence-inspiring, forgiving ride on normal trails.
Is a bamboo frame strong enough for expeditions and a loaded bike?
Will it survive cold, wet, sand and salt?
Finished frames are sealed with epoxy resin, so they shrug off cold and wet. After beach or salt rides, rinse off sand and salt, dry the bike, store it indoors and check the joints regularly.
What gearing and components does it take?
The frame is the frame — you add fork, fat-specific wheels, drivetrain, bars and finishing kit (a fat-tyre fork and wide rims are the parts to get right). Source them from any bike shop, or take a matched component pack from us and we'll advise on fat-specific spec.
