Rationale
Licensing vehicles is difficult, complicated, and expensive. 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.

| 2 | Motors | |
| 1 | 68mmx113mm bottom bracket - remove and store or recycle nut | Amazon |
| 1 | 3d printed bottom bracket holder | CAD |
| 2 | Bottom bracket mounting plates - to achieve 68mm width for mounting a sealed bottom bracket, on either side of a 1 1/2 inch (38.1mm) replimat frame, ~15mm thick plate must be used for the bracket on either side. This might work with PET. | |
