Reader Mike B. emails that while he was away between Oct. 5 and Oct. 9 his bicycle was gone from his front porch when he returned. Here’s the bike description, which Mike also put on the wall of the “Philadelphia Stolen Bikes” group on Facebook.

“Specialized Rockhopper mountain bike stolen from my front porch, 4400 block of Larchwood in University City, sometime between 10/5-10/9. The frame is gray/silver with chipped paint, with I think some old sticker residue. The tires are Schwalbe Marathons, and are pretty worn. There are two different styles of brake levers (one black, one silver), and shifters (right is a grip shifter and left is a trigger shifter), and the rubber grips are old and gummy. The saddle is black leather and foam, and is very worn (you might be able to read “Mikado” on it somewhere). It has a rigid fork and hardtail. It was locked with a cable lock (d’oh).”
