The Freelock Self-Locking Bicycle

The Freelock is a concept bicycle which features an innovative self-locking design. The bicycle seat doubles as a lock, eliminating the need to carry a lock and chain on all your cycling treks. The handlebars and body can be rotated to accommodate different bike racks and poles. The only problem could be that the wheels are now vulnerable to theft, a problem which the old-fashioned chain and lock took care of.
