mexican designer victor aleman designed the eco 7 folding bicycle to be as compact as possible, including
collapsible wheels. the design is intended for urban use and folds up to save space when not in use.
while folding bikes are nothing new, aleman takes his design to a new level with folding bike wheels.
each wheels is composed of six pieces connected through double-pivot joints. the spokes of the wheel fold
into the rim and fold out when opened up to provide structure to the wheel. the tire isn’t inflatable, allowing
it to break into segments. the bike frame itself also shrinks down in size when taken apart, folding into itself
and the core components. while the design may take awhile to fold and unfold, the compact size is ideal for
cramped urbanites.
