=Introduction= Freight bicycles, carrier cycles, freight tricycles, cargo bikes, box bikes, or cycletrucks are human powered vehicles designed and constructed specifically for transporting loads. Vehicle designs include a cargo area consisting of an open or enclosed box, a flat platform, or a wire basket, usually mounted over one or both wheels, low behind the front wheel, or between parallel wheels at either the front or rear of the vehicle. The frame and drivetrain must be constructed to handle loads larger than those on an ordinary bicycle.
=Challenges= Licensing vehicles is difficult, complicated, and expensive.
=Approaches= Bicycles (and velomobiles) usually don’t require a license. This makes them accessible to the young, differently abled, and societally disadvantaged. This velomobile carries two people plus groceries, is powered by a 1,000 Watt 48 volt wheel motor and recycled LiPo battery, and is recharged by the sun. Always ready to go, never needs to be plugged in. <gallery> Tricycle tadpole freight.png| Tricycle tadpole nofreight.png| Cargo cycle prototype.jpg| Engineers for a Sustainable World.jpg| Engineers for a Sustainable World2.jpg| 193288613 10159607858344180 5288582727327580769 n.jpg|Design by Marcus Frank 193404912 10226350607896705 8149498629237676630 n.jpg|Design by Marcus Frank N55-XYZ-Cargo-aluminium-bike1-a308cba56b1218e1777339600fdae48c-a06fa.jpg|N55 XYZ Cargo bicycle bottom bracket assembly XYZ-CARGO-TRIKE-closeup-1-Andere-e1399932614366.jpg|N55 XYZ Cargo bicycle bottom bracket assembly 32530705 1265292643607408 97768075725635584 o.jpg| XYZ Cargo Trike.jpg| 72419211 1675348185935183 5451352515637411840 o.jpg| XYZ Cargo truck.jpg| Suspension-example.jpg| </gallery>
