No one likes getting their bike, or any part of their bike, stolen. But so many people who ride bikes are relatively lax when it comes to locking them up properly. Not that locking up your bike properly will prevent theft in every case, but it sure can help with the quick, spur of the moment thefts. Improper bike locking can be a matter of laziness, lack of knowledge, or a lapse in your normal locking behavior, for example, when you’re just running into a coffee shop or doing a quick errand. In any case, theft can happen fast, so it’s not a bad idea to always lock up properly if you’d rather not deal with a stolen bike. Fortunately, Hal Ruzai from Bicycle Habitat in NYC came to the rescue in 2003 by grading your bike locking in a series of videos. He’s back at it again and recently came out with another video, which was on Streetfilms recently. Check it out and learn your bike locking grade.Hal Grades Your Bike Locking 2014 (Part IV) from STREETFILMS on Vimeo.
