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.
