I just bought my first bike after not riding for 20 years. 20 years ago I was 11, mind you, and I was riding BMX bikes.
I got the bike (an old KHS Montana) off Craigslist for $100. I wanted to get more familiar with riding, bike components, maintenance, etc. before dropping big bucks on a new ride.
Anyway, I look forward to learning as much as I can here.
