Beautifully simple, properly made, timeless cycles.

K1 Roadster

“Simplify, then add lightness.” - Colin Chapman, design engineer, inventor, founder of Lotus Cars.

This piece doesn’t belong to the shed or the basement. Nor to the museum. It wants to be ridden. And when not ridden, it should be proudly displayed in your living room (don’t let anyone know we said so).

Masterfully handcrafted by highly-experienced, third-generation professional craftsmen and craftswomen in Italy, to our design and specifications. TIG welded Italian Columbus, cycling-specific tubing. Columbus has over one century of experience in the bicycle tube design and manufacturing business.

Proper. Fundamental. Timeless.

The essential bicycle.

Although it can technically be painted or powdercoated, it would be a shame to cover up its sophisticated bare beauty. So we recommend leaving it nuda, with the options of an elegant polished glossy finish (as illustrated in these photos), or a rugged-looking brushed finish.
