What happens if I lose the special tool?

We offer replacement tools for purchase. Please contact ONIPAX and provide your order information for assistance.

Is this anti-theft bolt actually reliable for long-term city parking?

Yes. Standard quick-release levers are extremely vulnerable. Our system uses a unique 7-lobe pin design that cannot be removed with common multi-tools. It creates a significant deterrent, ensuring your saddle remains secure in public areas.

Will this fit my specific bike model, and is the installation difficult?

This M6x45mm bolt is a universal fit for most standard seatpost clamps. Installation is simple: replace your current quick-release lever with the ONIPAX bolt using the included specialized tool. It provides a secure fit in just a few minutes.

Can a thief just use a pair of pliers to unscrew this security bolt?

Our tamper-resistant design features a low-profile, smooth-surface nut that makes it extremely difficult for pliers to grip. Without the proprietary 7-lobe key, attempting to force it open is loud, time-consuming, and highly likely to fail.

Why should I choose a locking bolt over a standard hex-head bolt?

Almost every bike thief carries a standard Allen wrench set. A standard hex bolt offers very little protection. The ONIPAX locking bolt requires a non-standard tool, effectively stopping "crimes of opportunity" in their tracks.
