I started riding fixed in August, I'm 20. I actually didn't ride a bike regulary before then since middle school. My friends are all bike nerds mainly mountain and DH. They all have fixed gears too. My friend brought two bikes for us to ride when we visited Montreal, a SS mountain and his fixed Bottecia conversion. I kept asking to ride the fixed and I fell in love with riding it, so I bought my own. I've been riding for only a few months and I've become OBSESSED with it, for fitness for fun. Cycling was really the hobby I've been waiting for my whole life, nothing is more satisfying.
