The ULAC 52nd Street Combo is a robust and flexible chain lock designed for urban cyclists who need more versatility than a standard D-lock can provide. Featuring a 100cm reach, this lock allows you to easily secure your bike to wider objects like street lamps or thick fences. The chain is encased in a high-quality nylon sleeve to ensure your frame remains free from scratches and metallic noise while you ride.
This model utilizes a 4-digit resettable combination mechanism, providing 10,000 possible codes. It is a favorite for those who want to ditch the keys and enjoy a "grab and go" experience for cafe stops, gym visits, or office commutes.
4mm Hardened Steel Chain: Offers a reliable balance between cut resistance and lightweight portability for daily urban use.
100cm Length: Provides enough slack to lock the frame and front wheel together to a standard bike rack.
Resettable Combination: The 4-digit tumblers allow you to set a personalized code that can be changed as often as needed.
Durable Nylon Sleeve: Protects your bike's paintwork and prevents the chain from clattering against the frame during transport.
Compact Storage: The flexible nature of the chain allows it to be coiled tightly around a seatpost or tucked into a small frame bag.
Weather Resistant: The locking mechanism is designed to operate smoothly even after exposure to dust and light rain.

Commuters & Students: Ideal for those who make multiple stops throughout the day and want the convenience of a keyless system.
Weight-Sensitive Urbanites: At only 430g, it provides significantly more security than a cable lock without the heavy bulk of a 10mm master chain.
Multi-Bike Families: Because it is a combination lock, it can be shared between family members without needing to track or duplicate physical keys.
High-Theft Hotspots: The 4mm links are great for deterrents, but for unsupervised overnight parking in major city centers, a thicker 8mm chain or a Hardened U-Lock is recommended.
Extreme Security Needs: If you are securing a high-value e-bike, consider a "Sold Secure Gold" rated lock for maximum insurance compliance.
Precision Mechanics: If you prefer the tactile feedback and higher pick-resistance of a disc-detainer key cylinder, a keyed chain may be a better fit.
The 52nd Street is a fantastic secondary lock. If you are already using a U-lock for your rear wheel and frame, use this chain to loop through your front wheel and accessories. Because it is 100cm long, you can often reach from the bike rack, through the front wheel, and back to your U-lock, creating a multi-point security system that is a nightmare for opportunistic thieves.
