Kryptonite Evolution Mini-7 U-Lock with 13mm Hardened Steel Shackle and 4 ft KryptoFlex Cable, Compact Commuter Security

The Kryptonite Evolution Mini-7 is a compact, high-strength U-lock with a 13mm hardened steel shackle and a 4‑ft braided cable to secure your bike and accessories with commuter-friendly convenience.

If you want a durable, day-to-day bicycle lock that balances strong cut resistance with portability, the Evolution Mini-7 is built for urban riders, students, and suburban commuters. It combines a double-deadbolt, disc-style cylinder and a protective vinyl sleeve on the shackle with a bundled KryptoFlex braided cable so you can lock frames and front wheels or helmets without carrying separate products. The lock ships with three stainless steel keys and fits most bike racks thanks to its compact internal dimensions.

How does this lock resist common theft attempts?

The Mini-7 uses a 13mm hardened Max-Performance steel shackle and a double-deadbolt anti-rotation design to deter cutting, twisting, and leverage attacks. Its disc-style cylinder is engineered to resist picking and drilling while a sliding dust cover keeps grit out of the keyway.

• 13mm hardened steel shackle for cut resistance
• Double-deadbolt locks shackle on both sides for torsion resistance
• Disc-style cylinder with pick- and drill-resistant features
• Sliding dust cover protects the cylinder from debris

What accessories are included and how do they expand security?

Alongside the U-lock, the package includes a 4 ft KryptoFlex 410 braided steel cable to secure front wheels, helmets, or accessories. You also get three stainless steel keys and the FlexFrame-U bracket for on-bike transport.

• 4‑ft double-loop braided steel cable for secondary security
• Three stainless steel ergonomic keys for reliable operation
• FlexFrame‑U bracket for tool-free mounting to your frame
• Vinyl-coated shackle sleeve to protect paint and finish

Will this lock fit my bike and how heavy is it to carry?

The interior clearance measures approximately 3.25" x 7" (8.3 cm x 17.8 cm), which fits most standard bike racks and frames for a snug, secure lock-up. The lock weighs about 3.55 lb (1.61 kg), a trade-off between portability and robust protection targeted at everyday riders.

• Total weight: 3.55 lb (1.61 kg), commuter-friendly
