Hi, I am going to purchase a bicycle soon. I've already got a bike rack. It's been years since I have been on a bike, but I see people riding all the time. They are getting great exercise, it doesn't look as hard on the joints, and it looks like fun. So, I'm planning to get a bike that I can ride on a veloway, some on the street, and perhaps some on very easy trails. I want to get something that I won't decide to sell the next month or so. I want something that I will stay happy with for a year or two. I have no idea what kind of bike I should get, or if there are particular brands that are better than others. I assume that women need a different type of bike from men. I've had a look in a local bicycle shop, but that's all. Also, are there any other tips that I should know(other must-have items for female riders, something I should ask a sales person to do, etc.?)
