Duetta, a bicycle for sharing

A tandem bicycle, with practically the same size, weight, and cost of a standard bicycle.


Smaller and easier to maneuver than a conventional tandem bicycle.


Now you can say: “I’ll give you a ride!”


Safely ride along with disabled people.


It is easy to adapt the bicycle for different uses.

Sharing all

...the pedals

Two people pedaling and this way the effort diminishes and they enjoy together the sensation of riding.

...the bicycles

As a way of public transport in cities. We want Duetta to be used on this type of system everywhere!

...the design!

We want makers, cooperatives, technical schools, NGOs, companies, etc. to build upon our designs!
