The lock that fights back. The Bair Bikes Folding Lock with Alarm is a premium, multi-layered security solution for electric bike riders who want serious protection against theft — combining the rigid, cut-resistant strength of a folding lock with a built-in alarm that triggers at the first sign of tampering.

E-bikes are a significant and growing target for theft in Australia. A standard lock deters opportunistic thieves — but a folding lock with a loud built-in alarm takes your e-bike security to a whole new level. The moment someone attempts to move, cut, or tamper with your bike, the alarm activates — drawing immediate attention and sending would-be thieves running before they can make off with your investment.

Engineered for daily use and built to handle the rigours of outdoor parking in all conditions, this is the security lock for serious e-bike riders who refuse to leave their investment unprotected.

Key Features:

• Built-in motion sensitive alarm — triggers a loud siren at the first sign of movement or tampering
• Rigid folding link construction — hardened steel segments resist cutting, sawing, and leverage attacks
• Compact folding design — folds down small enough to carry in your e-bike bag or mount to your frame
• Secure key lock mechanism — hardened cylinder resists picking and forced entry
• Weatherproof construction — built to perform in coastal conditions, rain, salt air, and UV exposure
• Flexible folding links allow securing to a wide range of bike racks, poles, and fixed structures
• Compatible with all Bair Bikes e-bike models and most standard electric bikes

Folding Lock vs Chain Lock vs Combo Lock — Which Should I Choose? The Folding Lock with Alarm offers the highest level of everyday security — rigid construction plus an active alarm deterrent makes it the strongest all-round option. The Chain Lock offers heavy-duty passive security for high-risk overnight parking. The Combo Lock is the most convenient keyless option for quick stops and lower-risk areas. For maximum protection, pair the Folding Lock with Alarm with the Chain Lock when parking overnight or in high-theft areas.

Who It's For: Daily e-bike commuters who park in public places, urban riders in high-theft areas, and anyone who has invested in a quality Bair Bikes e-bike and wants the strongest everyday security solution available — because your e-bike is worth protecting properly.

Move it and it screams — the folding lock that gives thieves nowhere to hide.
