he idea behind Concept Bicycles called Versabikes is to make reselling your bicycle easier since they can be adjusted to fit multiple riders. The customizable bikes would also add to the comfort of the rider and even grow with the rider. Versabikes are a very unique design by Nathan Durflinger and are hypothetically made to be eco-friendly with pieces from materials like finished plywood, polycarbonate, or machined aluminum. The frame would work with all standard bike hardware and could be manufactured in two different sizes including a small size that could be adjusted as a child grew. A very cool concept that would greatly reduce waste is made a reality! Nathan can be contacted at the link below.
