I'm new to the sport and do not have a lot of money put aside to buy a bike. I'm a college student looking for an occasional weekend ride or a couple rides a week during the summer where I don't plan on going over 40 miles. The used bikes around me are not very appealing but I don't have more than 300-400 to spend on a new bike. I know this is problematic but I have willing to risk getting a cheap "walmart" bike. There are a few I have looked including random companies Gavin and Vilani, but also the Schwinns at walmart. Other than those, are there any entry level bikes in my price range, limited by my parents and bank account, that I would be able to find? and I fully understand that they are sub-par and I probably will have problems with it. Any help would be great!
