Bikes are cool icebreakers. I have to explain my bike to people sometimes.
Sometimes I don't want to -got errands, but ya, met a few cool old cyclists.
My fave tho -was from the grade school kids 'Your bike a custom?'

I talked a few, advised on thier bikes ..like jumping and kickstands are a no-go.
I chat cyclists up often, usually mtbers who have the tread reversed on thier tires and don't realize it.
Wish I had a track bike and a Velodrome to run..that sounds a blast.
