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.
