Good idea on the "Used" bike..

I looked at a cruzer at Walmart.. Now I am scared to buy it! SO CONFUSED!! I read that the tires would hit the chain and I would have to change them to smaller tires???? AhH! Thats the whole reason I was looking at it was for the larger tires!!!!!! ahh!

I will be needing alot, maybe too much, help if I am ever going to get this build off the ground! ahh!
