The Uno is the world's first real transformer. This revolutionary vehicle is similar to a unicycle at low speeds but transforms into a full motorcycle for higher speeds. The transitioning design allows the Uno to be nimble for mixed-use travel and compact for storage and parking while delivering all the benefits of a conventional motorcycle.
It's small enough to fit in an elevator or bring up to an apartment. It's stable enough to handle Boston's morning rush hour. The Uno now has three wheels. In Uno mode, the vehicle is a dicycle that balances on a single pair of parallel wheels, enabling unmatched nimbleness with an extremely tight turning radius. At high speeds, a middle wheel deploys forward and the outer wheels shift backwards transforming the Uno into a full street bike.
