Kryptonite Combo U-Lock

The Kryptonite Combination U-Lock is the strongest combination U-lock on the market and the only U-lock we stock.

Most U-locks under $60 look stronger than they actually are.

Most can be broken open with hammer strikes, and models with circular keys are easily picked open with a bic pen (as shown on YouTube).

The 4-digit, user settable combination cannot be picked and it eliminates the hassle of keys.

The included frame mounting bracket secures the lock on the bike for transport.

Includes a $1,750 anti-theft protection option available on kryptonitelock.com for $15 a year or $35 for 5 years.
