There are usually plenty of attachment options on the wheels and frame for securing them to a fixed object. A bike that is secured in this way cannot simply be picked up and carried away – which is a real security advantage. It may also be possible to use a combination of a brake disk lock and a chain. This combination is a so-called 2-in-1 solution. That means the brake disc lock can also be used without the chain and is the perfect compact companion for trips that include brief stops.
