A recumbent bicycle designed and built from A to Z.

Welded aluminium frame, plywood seat, direct drive and disc brakes: a complete vehicle, drawn and built in my workshop.

A complete vehicle

I started from a blank sheet: geometry, welded aluminium frame, steering, plywood seat, drivetrain and disc braking.

It rides, and you steer it lying back, legs forward.

The details that matter

Welded aluminium brake plate, caliper and disc, steering clamp: restraint comes from simple, well-thought-out parts.

What this project shows

Designing a complete vehicle takes the same skills as an industrial prototype: requirements, design, welding, testing. I put them at the service of your light-mobility or mechanical equipment projects.
