What's the best bicycle lock out there? My friend got that U-lock and her bike was stolen the next day.

most people here like the kryptonite new york chain locks and a kryptonite mini u-lock. i dont live in a big city or a high crime area, so i have not used any of those.

Knowing HOW to use a lock is as important as the brand of lock. About 90% of the bikes I see locked up in my neighborhood are NOT locked correctly. A U-lock needs to be attached to the rear wheel, just behind the seat tube.That lock needs to be attached to a sturdy steel pole set in concrete, not a flimsy bike rack, held together with two bolts. A second lock (which can be a "heavy duty" cable lock) secures the front wheel to the frame. Lock the bike where a crook is gonna be seen. I lock up next to the ticket booth at the movie theatre, not in the alley behind the theatre.

The best "cheap" lock is the OnGuard Bulldog U-lock. About thirty bucks. The "mini" version works well for road bikes and hybrids. The best expensive lock is the Kryptonite New York 3000 U-lock, for around seventy bucks. An eight pound Kryptonite chain is as strong as the four pound New York 3000. But, who wants to lug around an eight pound chain?

Hello!

I'm having trouble grokking this. If its just attached to the rear wheel, couldn't a thief cut the wheel? Or unbolt it (especially with the quick detach tires)? He couldn't ride it away, of course, but he'd only need to replace the tire to have a resaleable machine. Or do they just not do this?

Most of the "official" bike racks in my local neighborhood have all the metal low down -- you almost have to use a chain or cable.

The worst bike rack design I've seen is that of a nearly brand new library nearby that had a "big name" architect. I guess that architect hasn't been on a bike since he was 5. The "rack" consisted of a series of grooves in the ground into which apparently you are supposed to set either a front or rear wheel. On an adult bike this is not sufficient to hold the bike up. The groove collects rain water and debris. Next to the groove is a ring embedded in the cement. The ring is too small for even the end of a modest cable lock. I have to carry a spare lock to create a hole for the cable. Now that I think about it, I think I'm just going to use sign posts from now on.

Thanks!
Mark
