OTTOLOCK is designed for short-stop security and protecting against theft opportunists. It’s more secure than a cable lock and much lighter than a U-Lock. Starting weight at just 120g and coiling to a compact 3 inch diameter, OTTOLOCK is truly portable and always there when you need it. Security is addressed with a patent-pending, multi-layer steel and Kevlar® band design, making it extremely cut-resistant. Conventional theft tools like wire or bolt cutters will have a hard time against OTTOLOCK. It is not a replacement for a U-Lock. For maximum security, use a redundant locking method with both a U-Lock and a secondary lock. · LIGHTWEIGHT: Weighs only 120g - 235g and is easily stowed. So light and portable you won’t even know you are carrying it. · COMPACT: Coils to a diameter under 3 inches. Keep it in or around your saddle bag, backpack, in your pocket, or anywhere you want. · SECURE: Multi-layer steel and Kevlar® bands (18mm wide) make it very cut-resistant, and stronger than cable locks. · DURABLE: Chip-resistant Cerakote® paint and Santoprene® plastic that will not scuff or harm finishes. · RESETTABLE COMBINATION: 3-dial combination lock. You may also reset the combo as needed.
