Designed by Ronen Spector, a recent graduate from the industrial design department at Israel's Shenkar College of Engineering and Design, the Spine bike's top tube snaps away from the seat tube making the bike unrideable. With the use of articulated hinges the top tube becomes flexible and can be wrapped around immovable objects and secured back on to the bike.
Spector has produced a funny video showing the Spine bike in action, and portraying the disadvantages of carrying heavy chain locks.
On his YouTube page, Spector said:
"As the spine provides stability for the body, and damaging it will damage the body, so too damage to the locking mechanism [of the Spine bike], which is a part of the bicycle frame, will damage its structure."
