My name is Jackie. I am five feet, three inches tall. I am interested in riding a bike to work. The distance is eight miles, with four being on a busy road and four being on a bike path. I’m also interested in possibly doing some easy mountain biking at some point. I have no idea what size or type of bike to look for, but I have been looking at some on the Internet. However, I don’t like the idea of purchasing a bike online, so I also need to know where I should go to purchase a bike? What advice can you give me? this is a physical education question. please help

I would do a mountain bike personally, its tougher but If you want to do mountain biking then you're going to need something like that. Mountain bikes have great tires and last a long time. Try Dicks sporting goods or any place like that. But if you want a more comfortable bike then I would look into something that allows you to change the gears of the bike.
