From the Dept. of Losing Big Things in Public Places

This is so cool.

To see where they left their bike, they can look at the map on their smartphone. Pingbell uses Bluetooth Smart to let them know if they’re getting closer or not. They can ping the bell remotely if they still can’t find their bike, and it will ring itself. The sound is rich and full rather than an electronic beep, as it is made of brass so the noise is loud and crisp. Pingbell also functions as a conventional bell if you want to ring it while cycling along, and if you don’t want it to make a noise, it can blink a light at you instead to signal its location.

The Revenge of the Bike Thieved

This guy is one proactive victim:

In 2006, thieves stole writer Patrick Symmes’ bike in broad daylight on a crowded, New York City street. This inspired Symmes to set out to catch a bike thief — any bike thief.

He tells the tale of this revenge-fueled, cross-country journey in the Outside magazine piece “Who Pinched My Ride?” The story is filled with GPS trackers, police stakeouts and undercover stings in what Symmes describes as “the dangerous underworld of vanished bicycles.”

Story has lots of good advice on keeping your bike safe and some good caller stories. Worth a listen.

Safety in Numbers

Cool news about biking in general and in Philadelphia in particular:

As the number of bicyclists on Philadelphia streets has risen, cyclists and city officials have seen a counterintuitive result: The number of bike crashes and deaths has declined.

This “safety in numbers” phenomenon has been documented elsewhere, and safety experts believe it is because motorists become more alert to cyclists when there are more of them.
