U-lock ONGUARD NEON 8152BU — U-shaped bike lock 115 mm shackle height, 292 mm shackle width, includes mounting bracket and 2 keys (blue)

ONGUARD NEON 8152BU is a U-shaped bicycle lock designed for everyday security of bikes and similar small vehicles. The hardened steel shackle provides a compact locking profile with an internal height of 115 mm and a width of 292 mm, allowing the lock to secure a bicycle frame and one wheel to fixed objects. The package includes a handlebar or frame mounting bracket for convenient transport and two keyed blue keys for regular use.

Advantages

The U-lock construction with a hardened steel shackle offers resistance to cutting and leverage attacks relative to lightweight cable locks while maintaining a compact size for urban mobility. The included mounting bracket simplifies carrying the lock on a bike without additional accessories. Two keys reduce the risk of being locked out and the bright blue finish improves visibility when stored or mounted.

Suitable for

• Securing commuter and city bicycles in short-term stops
• Locking children's and small-frame bikes
• Attaching a bike frame and one wheel to bike racks or fixed posts
• Use on campuses, urban streets and other low- to medium-risk environments

Key specifications

• Shackle type: U-shaped, hardened steel
• Shackle internal height: 115 mm
• Shackle internal width: 292 mm
• Finish/color: blue
• Includes: mounting bracket and two keys

How to use

Position the shackle so it passes through the bicycle frame and a fixed object or through the frame and a wheel, then insert the crossbar and turn the key to lock. Use the mounting bracket to attach the lock to the bicycle frame or handlebars when not in use; secure the bracket with the supplied fasteners and slide the lock into place until it clicks. Keep both keys in safe but accessible locations to avoid being locked out.

Usage recommendations

For best security, lock the frame and at least one wheel to an immovable object and park in well-lit, populated areas. Combine this U-lock with a cable or secondary lock for added protection of detachable components in higher-risk locations. Regularly lubricate the key cylinder with a graphite or silicone-based lubricant to maintain smooth operation.
