Some cargo bikes are huge, like this Australian Trisled. This four-wheeled quadcycle is capable of moving huge loads on its massive two and half-meter long tray-top. The FlatBed Truck freight bike sells for a little over $4,000, so it’s for serious transporters only. Treehugger also showcased five cool cargo bikes and explored the future of cargo on bikes (and the present, too!)
Another form of cargo: kids. In the Netherlands they have this figured out thanks to Bakfiets, and they have built a kid carrying, cargo hauling, folding trike called the Feetz Tribike. These tried and true designs are being put to work every day, from Boston to Portland.
