ROBUST AND PRACTICAL Grab, click and your bike is locked like that – with reliable ABUS lock protection. Frame locks are basic protection for your bike - for more security on the road. Just want to pop into the bakery? With a quick twist of the wrist, you can practically and quickly protect your bike from spontaneous theft - for example with our frame lock 4650. Permanently mounted on the bike tyre, it can be locked and act as an immobiliser. This way, bike thieves have no chance to make easy prey and ride away. For extended protection, the frame lock allows the device to connect an additional chain. With the accessory options, you can alternatively chain the wheel to a fixed object. Decide for yourself whether you want the lock in the NR or R version. With frame locks that have an R in the product name, the key cannot be removed when the lock is open. It stays put and you don't have to stow it away when you ride your bike. Those who prefer to remove the key can choose the NR version.
