I think I can now say that I am an experienced rider and I wouldn't go as far as to say "bike mechanic," more like a bike fixer-upper since I have never actually been paid, in money, to do it. I currently don't own a car so my bicycle is my main form of transportation which means that it always then must be in perfect working order; something I have been working on achieving over the past 3 years.
