Onguard Pitbull Diamond 8002 U-Lock – High Security – 14mm Shackle

Protect your bike with confidence using the Onguard Pitbull Diamond 8002 U-Lock — a heavy-duty, high-security lock designed for demanding environments and ideal for securing modern e-bikes.

Built to withstand serious theft attempts, this lock combines advanced locking technology with a reinforced design that offers both strength and versatility.

Diamond Rated Security (Maximum Protection)

The Pitbull Diamond 8002 carries a Sold Secure Diamond rating — the highest security level available.

This makes it:

• Suitable for high crime areas

• Ideal for high-value bikes and e-bikes

• Approved for many insurance requirements

If you're investing in an electric bike, this is the level of protection you should be looking for.

Designed with E-Bikes in Mind

E-bikes often have larger frames, wider tubing, and bulkier components, making standard locks restrictive. The Pitbull Diamond 8002 features a longer and wider shackle, giving you more internal space to lock around frames, wheels, and fixed objects with ease.

Perfect for:

• Step-through and oversized e-bike frames

• Locking both frame and wheel together

• Securing to thicker bike racks or street furniture

Maximum Security for Urban Riding

Engineered for medium to high-risk environments, this lock delivers serious protection:

• 14mm hardened steel shackle resists cutting and leverage attacks

• X4P Quattro Bolt system secures the shackle on all four sides

• Anti-pry design reduces weak points

Advanced Anti-Theft Technology

• Z-Cylinder locking system resists picking, drilling, and bumping

• Reinforced internal construction for durability

• Automatic keyway cover protects against dirt and weather

Bike-Friendly Protection

Despite its strength, the lock is designed to protect your bike’s finish:

• Double rubber-coated shackle prevents scratches

• Co-moulded crossbar cover with metal end caps

• Built to handle everyday knocks and drops

Why This Lock Is Ideal for E-Bikes
