Riding my patrol bike around the university, I see a LOT of bikes. It's one of the things we keep track of, trying to prevent bike theft.

Being a mechanic as well as a cop, I can't help notice how many bikes I see with the quick-release levers on the hubs backwards.
This should not be difficult; they are even marked "close" and "open" in most cases. Yet it's very common.
Another thing you see all the time is bikes "cross-chained" badly; the big ring up front and the big cog in the back, or vise-versa...
Not to mention chains that have never seen a drop of lube. Often, you can hear the kiddies coming... Sounds like a threshing machine.

So? What happens when you try to teach one of these unfortunates what they're doing wrong?

HELLO! It's a university campus. If they're so smart why do you suppose they still have to go to school?

the title of this thread is sooo misleading. i was seriously expecting pics of girls on bikes or something along those lines.

perhaps there is a prankster going around opening all the quick releases. what a great prank.

Yeah, I also see nearly eveyone with their seatpost slammed all the way down into their seat tube (too low). Lately with the surge of FG/SS riders I see a LOT of stupid stuff, like brake cables run without housing.

People aren't very bright....what's the point?
