How the YERKA Built-In Lock Actually Works

Most bike security relies on remembering to bring a lock, finding something solid to lock to, and hoping neither the lock nor the mounting point gets defeated overnight. YERKA takes a different approach. The frame itself is the lock. The down tube separates and threads through a fixed object, then reconnects to the frame to secure the bike in place. There is no separate lock to carry, no cable to forget at home, and no compromise on frame rigidity when you're riding. It takes seconds, and it works with any solid street furniture, a pole, a fence rail, a rack, without needing a dedicated locking point.

Which YERKA Bike Is Right for Your Riding

The V3 is the entry point: a clean, lightweight city bike that suits flat urban routes and shorter commutes. The V4 Rigid steps up with a Shimano Nexus 3 internal hub for smoother, lower-maintenance gear shifting, making it a better fit for longer or hillier daily rides. The V4 Suspension adds a front fork for a more comfortable ride on rougher city streets and mixed-surface commutes. All three share the same core lock mechanism.
