The frame lock RS 453 Protect-o-Connect is the ideal basic security for your bicycle or e-bike. Installed firmly on the frame, it can be locked or unlocked in a single movement. If you want to park your bike or e-bike for a longer period of time, the RS 453 can be extended with the ZR 355 plug-in chain (included in the set). This enables the rider to lock the bike to a fixed object.

The Balloon version of the frame lock (opening 72 mm) is suitable for particularly wide tires. The assembly is simply done with the supplied mounting clamps or directly with screws on the bicycle frame. The practical TRELOCK saddle bag is perfect for transporting locks or other accessories. For example, Trelock additional chains for frame locks can be transported easily with the bag. The surface material is weatherproof and the maximum load is 2 kilograms.
