Premium lightweight bike locks

I am Professor Neil Barron, the founder and inventor of Litelok, a former Aeronautical Engineer (Rolls-Royce aero engines), designer and keen cyclist. After having several bicycles stolen on the streets of London, and fed up with having to carry around heavy bike locks, I thought there must be a way to create a high-security, lightweight bike lock. Many cyclists I spoke to agreed that it didn’t seem right that as bicycles were getting lighter and lighter, secure bike locks were getting heavier and heavier.
