U-lock ONGUARD Pitbull STD 8006E by ONGUARD — 14 mm shackle, 90 mm clearance, 140 mm body, 5 coded keys

ONGUARD Pitbull STD 8006E is a U-lock intended for securing e-bikes and bicycles in urban and suburban environments. It combines a 14 mm hardened steel shackle with a compact 140 mm body and 90 mm internal clearance to accommodate frames, wheels or fixed objects. The lock is supplied with five coded keys, allowing for key replacement without rekeying the whole set and enabling controlled access management.

Advantages

The 14 mm hardened shackle offers enhanced resistance to cutting and sawing compared with thinner shackles, while the 140 mm body provides a stable, rigid anchoring point. The 90 mm internal clearance balances compatibility with common bike frames and reduced leverage space for attackers. Five coded keys are included to simplify key loss replacement and to keep spare keys available without compromising the lock’s original keying system.

Suitable for (tasks / use cases)

• Short-term outdoor parking in urban areas
• Securing e-bikes and conventional bicycles to racks or fixed posts
• Commuting and quick stops where a rigid U-lock is preferred
• Situations requiring spare or replacement keys kept under a single code

When it may not be suitable

The ONGUARD Pitbull STD 8006E is sized and specified for typical city use and short-term parking; it may not be the optimal choice for long-term unattended storage in high-risk locations where heavier or alarmed security solutions are recommended. The 90 mm internal clearance can limit locking options on bikes with very large frames, integrated locks or unusual geometries.

Key specifications

• Shackle material and thickness: hardened steel, 14 mm diameter
• Internal clearance: 90 mm
• Lock body length: 140 mm
• Number of keys supplied: 5 coded keys
• Lock type: rigid U-lock (D-lock) suitable for frame and wheel locking

How to use

Position the shackle around a fixed object and through the bike frame or wheel so the lock body rests against the shackle. Insert one coded key and turn to lock; verify that the shackle is fully seated and the mechanism engages. To unlock, insert the key, turn it and pull the shackle free. Keep spare coded keys in separate locations to reduce the risk of being locked out if one key is lost.

What to consider before purchase

• Measure frame and rack dimensions to ensure the 90 mm clearance is sufficient for intended locking points
• Decide whether rigid U-lock geometry fits your common parking situations versus longer cable or chain additions
• Plan for spare key storage since the product comes with five coded keys for controlled replacement

Usage recommendations

For maximum effectiveness, lock the frame and one wheel to an immovable object and position the lock so the shackle is close to the ground and the key cylinder faces down or sideways to make tampering more difficult. Combine the U-lock with a lightweight cable or chain to secure additional wheels or accessories when needed.
