Its sturdy construction and reliable locking mechanism make it ideal for various applications, providing long-lasting protection against theft.

## Long description

The MASTER LOCK 8290EURDPRO Black 550 mm is a steel ring lock designed to secure bicycles, scooters and similar personal transport devices. Constructed from hardened steel with a protective black finish, the lock measures 550 mm in length and provides a physical immobilization point for the vehicle frame or wheel. The unit incorporates a mechanical locking cylinder and mounting points suitable for fixed installation on frames and forks where a ring-style immobilizer is required.
Advantages
The ring lock offers robust mechanical resistance due to its steel construction and hardened components, reducing the risk of forced removal. Its black protective coating helps resist corrosion and environmental wear when mounted outdoors. The length and shape are intended to fit a wide range of frame geometries, and the integrated mounting system enables secure, semi-permanent attachment to the vehicle. The simple mechanical cylinder is easy to operate without batteries or electronics, ensuring reliable long-term use.
Suitable for
Securing city and commuter bicycles when parked in urban areas
Immobilizing scooters and small electric vehicles as a basic theft deterrent
Use as a supplemental lock in combination with chain or U-locks for higher security needs
Installation on frames or forks where a ring-style frame lock is supported
Key specifications
Material: hardened steel body and shackle
Finish: black protective coating
Length: 550 mm overall dimension suited for frame attachment
Lock type: mechanical cylinder (key-operated)
Mounting: fixed installation points for frame or fork attachment
How to use
Mount the ring lock to a compatible point on the bicycle or scooter frame using the supplied or appropriate fasteners, ensuring the lock aligns with the wheel or frame tube for effective immobilization. Insert the locking shackle or ring through the wheel or around the frame tube, then engage the key-operated cylinder until it clicks and the mechanism is secure. Confirm the device prevents wheel rotation or frame movement before leaving the vehicle unattended.
Usage recommendations
For improved theft protection, use the ring lock in combination with an additional high-security chain or U-lock to secure the vehicle to an immovable object. Regularly lubricate the cylinder with a graphite-based lubricant and check mounting fasteners for tightness. Avoid prolonged exposure to extreme weather when possible and inspect the protective coating periodically for signs of corrosion or wear.
