The dude riding the wrong direction in the bike lane in the dark with no lights, helmet not strapped on and looking at his phone while riding no hands is a person on a bike (with a suicide wish). Grandma riding her trike being careful still makes cyclist. The commitment is there, whether it is exercise or the way to get to the store. That said, there are a lot of people on bikes, and also a lot of cyclists. You don't need to ride in a club, with a $5000 aero road bike with Lycra to be a cyclist, though they definitely are part of the group. That said, I mostly ride road with Lycra, though you might see me and the wife out on our cruisers in my shorts and a t (somewhere I did not get the letter stating men over 50 must spend the summer shirtless!).
