This is for people not from Pittsburgh.
"Bumper Bike" as he is known locally is one of the most visible cyclists in Pittsburgh.
He is really stoked on life each time I see him. He doesnt care if you are on a fixie, in spandex, or on a junk bike, he will still smile and be stoked. He even offers to hook up your bike for you.
