With Xtracycle's FreeRadical you can turn an ordinary bike into a long tail cargo bike. It's an extension of the rear triangle using your existing rear wheel. The beauty of this is that you don't need to invest a lot of bucks in a new bike. We have a couple of the original FreeRadicals in stock. They've been out of production for a while so now's the time to pick one up before they're gone for good. It's ideal for hauling stuff (or bigger kids with the addition of U-tube foot rest and cushion.) We're selling the FreeRadical extension along with platform, bag, and kickstand for $400 (the combined group usually retails for $470.) Come in and try it out. We have one set up on a 26" wheeled Kona Cinder Cone (also on sale!) Call or stop in for more info.
