My 3 pesos. Any bike will do. Some will do better than others. I use a road bike, but sometimes wish I had mounting points for racks. If you must, a cheep $100 bike from WalMart will get the job done, though there are a lot that will do it better. I usually recommend against suspension bikes unless you plan to do some really serious off roading. Shocks only slow down a street bike. I am not talking about racing, but I do like to get home in decent time.
