The bicycle may be doomed to an early extinction if the Ts-Tricycle ever comes onto the scene. This tricycle was designed by Matias Conti as a transformable tricycle that can take up to four different shapes.

Being able to switch up the shape of the Ts-Tricycle means that there is almost nowhere it can't go. Cross-country, steep hills, and off-road areas are all accessible to the Ts-Tricycle thanks to its unique folding design. The Ts-Tricycle may be a concept now, but I'd still watch my back if I were the bicycle.
