bicycle chains, bicycle inner tubes, Kevlar (aramid fiber), square-headed steel tube, eye bolts

Together with a facility for the disabled with its own cycle workshop, this cycle lock was developed from disused cycle parts: Chains (highly flexible) are placed inside inner tubes as a protective coating and heat-resistant Kevlar (aramid fibers). A personal padlock can be attached to the steel caps made of square steel tubes and screwed in rings screws.
