What makes it different
No welding, no workshop
Build the whole frame on your kitchen table with basic hand tools — everything else is in the kit.
Everything in the box
Bamboo, the jig, metal fittings, resin, fibre and 15+ hours of step-by-step video — you only add the components.
Every kit funds learning
Your build helps fund accredited skills courses in prisons and schools. You learn a skill — so does someone else.

| Frame size | Rider height | Inseam |
|---|---|---|
| XS | 148–163 cm | 68–74 cm |
| S | 160–173 cm | 74–80 cm |
| M | 170–183 cm | 78–86 cm |

| 2XL | 200 cm + | 98 cm + |
Inseam is the better guide — measure barefoot, floor to crotch. Bands overlap on purpose: if you fall between two, choose the smaller frame.
No sizing gamble: you build your frame to fit you. Use your height and inseam to pick your size.
Your frame's size is set on the jig you build on — so pick the size that matches your fit, then fine-tune with seatpost, stem and saddle. Being between sizes is normal: build the smaller one.

Complete your build, the easy way.
The kit is the frame. Add a matched component pack — fork, wheels, groupset, finishing kit — and you're ride-ready. Or source parts from any bike shop; your frame fits all major groupsets.
Everything to build the bamboo gravel frame.
Fork, wheels, groupset, bars, saddle and finishing kit.
A complete, one-of-a-kind gravel bike — built by you.

What you'll need at home.
Basic hand tools
A hacksaw, files, sandpaper, a measuring tape — no power tools. Everything else is in the kit.
A bit of space
A sturdy table around 1200 × 600 mm and a spot the frame can sit undisturbed while joints cure.
A few weekends
25–35 hours across multiple sessions. No rush — bamboo is forgiving and most mistakes are fixable.
Four stages, across a few weekends.
Set the geometry
Lock your own geometry on the jig — built to the measurements we work out together.
Join & wrap
Bond the tubes with epoxy and wrap each joint with carbon-fibre tow.
Cure
Leave it for a full cure — that's where maximum joint strength comes from.
Sand, seal & ride
Sand smooth, seal the bamboo, fit the headset and bottom bracket. Adventure awaits.
Your geometry, your discipline, built by your hands
Bamboo's natural vibration damping takes the edge off rough trails — ideal for bikepacking. Frames are compatible with all major groupsets and can be built around Shimano GRX or Rohloff geared hubs.
I wanted something nobody else had. Now I ride a bike that's completely mine — geometry, shape, everything.
Custom kit builder, Bespoke geometry buildIn the kit
Heat-treated Moso bamboo tubes (with spares), a full-size frame blueprint, a plywood alignment jig, the CNC metal parts that the steering, cranks and wheels bolt to (head tube, bottom-bracket shell and dropouts), carbon-fibre tow (the reinforcing fibre you wrap each joint with), two-part epoxy resin, and an illustrated manual plus 15+ hours of step-by-step video tutorials.
You'll add
Fork, wheels, groupset, handlebars, saddle and finishing components. Grab a complete component pack from us, or source parts from any bike shop.
You've got this — and we've got you
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.
Tools you'll need
- Hacksaw
- Files
- Sandpaper
- Tape measure
- A rounded wood file
- Electrical & masking tape
- A 1200×600mm board
- No power tools needed

Rated by the builders who made one
I went from knowing nothing about bicycles to having built one. Two years on, I still burst with pride riding something I made myself.
