Frequently Asked Questions

Find answers to common questions below

How does the YERKA anti-theft system work? ⌄

YERKA’s patented system splits the bike frame itself to lock around any fixed object. To steal a YERKA, a thief would have to destroy the frame — making the bike worthless. No separate lock is needed.

Is YERKA available in Australia? ⌄

Yes — YERKA anti-theft bikes are available exclusively through NG Mobility in Australia. We stock the YERKA V3 and V4 Rigid models with fast Australia-wide delivery.

Can a YERKA bike be stolen? ⌄

YERKA is virtually impossible to steal without destroying it. The frame IS the lock — meaning any theft attempt permanently damages the bike. This makes YERKA the most secure bicycle available in Australia.

What type of rider is YERKA designed for? ⌄

YERKA is designed for urban commuters who park their bike in public spaces daily. If you lock your bike on the street, at a train station, or at work, YERKA eliminates the risk of theft without the hassle of carrying a heavy chain lock.

Does YERKA come with a warranty in Australia? ⌄

Yes — YERKA bikes purchased through NG Mobility include a manufacturer warranty with Australian support from our Brisbane team.

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.

Yerka Bikes at NG Mobility

All three YERKA models ship free across Australia on orders over $150 and are backed by NG Mobility's price match guarantee. If you ride an e-bike and want a conventional backup or second bike, YERKA pairs naturally with any model in the electric bikes range.
