U-lock Kryptonite NEW-U EVOLUTION STANDARD Black Orange 102mm 229mm 1.59kg

The Kryptonite NEW-U EVOLUTION STANDARD Black Orange is a robust U-lock engineered to secure bicycles with a balance of strength and practical size. With an internal width of 102 mm and height of 229 mm, and a weight of 1.59 kg, this lock offers a compact yet solid solution for everyday bike security. The unit includes three keys to simplify shared use and spare-key needs. Its hardened shackle and reinforced crossbar are designed to resist common attack methods while remaining easy enough to carry on commutes and urban rides.

Advantages

This U-lock combines hardened steel construction with a reinforced locking mechanism to provide high resistance to cutting and levering. The 102 mm internal clearance accommodates most bicycle frames and many wheel combinations while minimizing leverage points for thieves. The lock’s orange-accented design improves visibility when mounted on a bike or left in public spaces. Inclusion of three keys reduces the need for immediate key duplication and supports multiple regular users.

Suitable for

• Securing city and commuter bicycles to fixed objects such as bike racks and posts
• Short- to medium-duration stops in urban environments
• Use when combined with a cable or secondary lock for extra protection of wheels or accessories

How to use

Position the lock so the shackle passes through the bike frame and around a secure fixed object, ensuring the locked area includes at least one structural frame tube. Insert the shackle into the crossbar and turn the key to engage the locking mechanism; verify the shackle is fully seated before releasing. When leaving the bicycle for longer periods or in higher-risk locations, pair the U-lock with a secondary security cable to protect wheels and accessories. Store the keys in a safe place and carry the spare separately to avoid simultaneous loss.

Usage recommendations

For optimal security, attach the lock through the bike frame’s triangle and combine with an accessory cable to secure wheels or saddle. Regularly inspect the lock for signs of wear or corrosion and lubricate the keyway annually with a graphite or silicon-based lubricant to maintain smooth operation.
