have you ever wondered if the bike rider has stolen the bike?

is it always the same person?

I would be suspicious too, but then again, I would ride in tennies. But not street clothes! Weird....

I have been seen riding in street clothes and tennies/sandles with my clipless pedals if I'm just nipping out. But I do see your point. A news story in the local paper from home just last week....the police stopped a student late at night drunkenly riding a bike that very obviously wasn't his. Turns out he had stolen it and he was made to hand it back to the owner himself. The owner, a 6 year old boy, was somewhat disappointed though. He was hoping for a new bike since his had been stolen. Now he was stuck with the returned old bike for a while longer.

well, actually, I can be seen riding in street clothes almost every single day on my fancy road bike. I wear my expensive red Italian leather shoes(SIDI) and helmet as well..

I also would wear street clothes on my roadie before I had my commuter... but, I see the point. Though, the police reports say stolen from being parked outside. Who would leave an orbea outside and unattended? I don't leave my roadie parked outside at all... if it can't come in with me when I run inside, I take the great blue tank (my commuter). You are in So Cal? Yeah, I can see someone stealing high end bikes and then riding them in their baggie shorts... (I grew up in south OC). Well, take special care of your road bike...

I routinely wear street clothes (and a backpack) while riding my $3.5k carbon race bike. I like to ride it, so when I can I commute on it. No point in full kit to go 3 miles to work...

I do tend to wear my bike shoes though, only because the contact area on my pedals is puny (mountain bike pedals).

But yes, I have seen bikes that I thought just HAD to be stolen. Like a nearly new, but obviously abused Specialized, must have been a 3-4k bike, with very old school cage pedals that were beaten to heck. The rider looked like he hadn't showered in a week and his clothes and shoes were in dire need of replacement...

There was an article in Bicycling a while back (click here) about day laborers and bikes.
Basically , Stolen bikes are a lot less expensive than a Huffy.
I've seen bikes that don't belong with the ride (Specialized Tarmac, Rivendell Rambolieut, and a Vitus 992(though that may be a goodwill special))
