I was looking at a couple of Police bikes at the fair last weekend and was trying to figure out what kind they were. It looked like a BMW emblem on top of the fork tube. I looked a little closer and saw BMW stamped into the side of the frame too. I didn't even know BMW made bicycles!!! They looked a lot like the cheap aluminum Wal Mart bikes except they were silver. Not sure what componenets they had on them but they looked pretty cheap.
I think maybe this is the bike those police bikes were based on...
