I find it stocking that sooo many people out there can ride bikes , but there are still so many cars out on the streets. Bikes cost way less and there easier to maintain. In my city there is a bike system and it makes it easy for people to be able to use the bike the time needed instead of going to go buy one. As a young women I was never taught to ride a bike and I always wanted to learn because it is a great part of exercise. With the millions of people there should be more of us trying to make this happen.
