First of all, what exactly is a "cruiser" bicycle? Second...Walmart has some nice classic looking bikes for under $100. Balloon tires, rack on back and coaster brakes. Are coaster brakes a problem for bike motors? Do ballon tires do much to eliminate rough ride on gravel roads? I currently am using a mountian bike. It rides like a truck and vibrates like heck and bumps...well forget it. Anyway, I have determined that most of my comfort problems are because the bike is just to small and does not have allowance for adjustment. So I am in the market for something cool, comfortable and under $100.
