At first glance, the Tube Light Lock might appear to be a small and simple ring around the seat post of your bicycle, so you might be surprised to learn of its dextrous features. This clever product provides the peace of mind that comes with both safety and security while you're riding and when your two-wheeler is parked.

Kyuho Song of Seoul, Korea, was inspired by the lifesaver ring, choosing that shape for this compact cycling accessory. Twist it to open its donut form and fix it to the frame of your pushbike. Serving as a combination lock, the product contains a retractable cut-proof cord that you can pull out and wrap around a bicycle rack. The Tube Light Lock also fully illuminates with LEDs to act as an anti-theft bike light.
