The Abus U-Mini 40 U-Lock provides beefed up security in a small form factor for compact theft-protection that's hard to defeat. Safety comes in the way of a 14 mm (0.55 in) hardened-steel shackle and a premium anti-manipulation lock cylinder that double bolts it into the lock body. The casing is also made of hardened steel to thwart tampering, and a soft-touch housing cover is easy on bike frames to keep paint and components unharmed.

  • Diameter: 14 mm (0.55 in).
  • Weight: 980 g (2.16 lb).

Super strong, but...

I had one of these, and it was great until one day it wouldn't unlock. The key turned all the way, but one of the teeth wouldn't retract, so I couldn't open it. I eventually had to have the police cut the lock for me. On the bright side, it took them 20 minutes to cut it with bolt cutters with three-foot-long handles, so it's strong. Whether it's a good buy depends on whether the lock mechanism failing like that is a common problem.
