50, is that all? Wish I was only 50. I started riding seriously again at 50 back in 2000. Almost 19 years later, I've bought 7 bikes. Still have 6, one was killed by a car - while I was riding it. Better get started, you have a lot of catching up to do. My bikes are all road bikes, 3 vintage steel, 2 modern carbon, one in between aluminum. Never had a hybrid or a mountain bike. Just do it.
