## Long description

The U-Lock bike lock MASTERLOCK QUANTUM 8228 in green is a hardened U-shaped shackle lock designed to secure bicycles and similar two-wheeled vehicles. It provides a compact, portable solution for everyday protection, allowing cyclists to lock the frame to fixed objects and reduce risk of opportunistic theft. The mechanical design focuses on simplicity of use, robust materials and a straightforward locking action suitable for commuters and urban cyclists.
Advantages
This U-lock features a hardened steel shackle that resists cutting and prying attempts while maintaining a compact form factor for easy transport. The lock’s mechanical cylinder offers reliable operation without batteries or electronics, and the protective coating helps prevent scratches to the bicycle frame. The green finish improves visibility and identification in crowded bike racks.

Key specifications
 Lock type: U-lock (D-lock) with hardened steel shackle
 Finish: green protective coating
 Operation: mechanical key cylinder
 Design: compact, portable shape for frame attachment
 Primary use: securing bicycle frames to fixed objects
How to use
Position the U-shaped shackle around the bicycle frame and a fixed object such as a rack or pole, making sure the shackle passes through a secure part of the frame. Insert the crossbar or locking mechanism and turn the key to engage the lock. Verify the shackle is fully seated and the lock is secure before leaving the bicycle. Keep the keys in a designated, safe place and avoid forcing the key or shackle if resistance is felt.
Usage recommendations
For best results, use the U-lock in combination with a secondary cable or chain to secure wheels or accessories. Place the lock as close to the locked object as possible to minimize leverage points. Store keys in a protected place and periodically check the lock for corrosion or wear, especially after exposure to wet conditions.
