Simply dismount the bike, briefly position the 8.5mm shackle and you’re done. The PRO TECTIC™ 4650 Frame Lock is extremely easy to use and offers good protection in regions with a low to medium risk of theft. Those who like it even more secure you can easily add the ABUS CHAIN Frame Lock Chain as a second lock. It easily inserts into the additional lock housing.

Note that the frame lock only locks the rear wheel, if lifted the bike can be wheeled away. The addition of the IvyTex Chain Adapter allows you to lock your bike to a pole for added security.

The Abus 4650 installs at the rear of the rear wheel for easy access. Mounting hardware and adaptors are provided.
