I'm 45 and still ride a kids bike. Life is good and it's great to be able to still ride at my age. I've been riding on and off since I was 14 and still try to get out every day for a couple of hours to ride. My advice to all the younger riders out there is don't give up. Keep riding even if you find new things you like. Don't let anybody tell you it's a waste of time and you can't make money doing it because you can make a living doing what you love no matter what it is. All you have to have is perseverance and determination to achieve your goals. Look for ways to make it happen and a way will appear.
