Inseam is the better guide — measure barefoot, floor to crotch. Bands overlap on purpose: if you fall between two, choose the smaller frame.
Outside these bands, or between sizes? That's exactly what a custom build is for — we design around your body and riding style.

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.

in 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), flax fibre (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'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.

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 same hand-build every kit follows — start to finish, on camera.
Bamboo naturally dampens vibration, allowing the smoothest ride.

rated by the builders who made one
I wanted something nobody else had. Now I ride a bike that's completely mine — geometry, shape, everything.
Custom kit builder, Bespoke geometry buildI went from knowing nothing about bicycles to having built one. Two years on, I still burst with pride riding something I made myself.
Louise · home-build road bikebefore you build.
Do I need to know anything about frame geometry?
No. This is the whole point of the custom kit — you don't design it alone. Send us your height and inside-leg measurement and tell us how you want to ride, and we work out the tube angles, lengths and fit with you, 1:1, before anything ships. You bring the body and the riding style; we bring the geometry.
How does the custom process actually work?
First we talk through your measurements, your chosen discipline and how the bike should feel. We design the geometry together and agree it with you. Only then do we prepare and ship your kit — bamboo tubes, a jig set up for your unique geometry, metal inserts, flax fibre and epoxy — plus the full video tutorials. You build it at home with direct support throughout.
Which disciplines can I choose?
Any of them — road, gravel, MTB or city. We'll work with you on the frame type and the geometry that suits it, whether that's a fast road position, a stable gravel/touring setup, a slacker trail bike or an upright city commuter.
What measurements do I need to send?
To start, your height and inside-leg measurement, plus a sense of your current bike and how you'd like this one to feel. From there we'll guide you on anything else we need. No special tools or fitting knowledge required on your side.
How long does it take, and why does it cost more than a stock kit?
A custom build takes longer than a fixed-spec kit because you're designing the geometry from scratch with us first, and the build itself runs longer (more design and prep time up front). The price reflects the bespoke 1:1 design work and a jig set up specifically for your geometry — you're paying for the consultation and the made-to-measure fit, not just the materials. Lead time depends on the design stage; we confirm it with you when we scope your build.
