I have a mountain bike but tend to take it easy. I choose quiet routes, that is with few cars on them. It seems wherever I go I get the occasional near miss. About a year ago a truck nearly wiped me out when he came out of a side road and saw me at the last moment. Two summers ago I went over the handlebars and scraped myself in different places and got a mild concussion even with a helmet on. Yes I take it easy but enjoy the ride.
