Conversion TimeTook about 6 months to build (weekends) and about a year to get on the road. Most of time was used waiting for NY-DMV paperwork.
Conversion CostAbout 12K but I'm including accessories such as solar array, cycle shelter, upgraded parts, storage chest, other tools that I would not have otherwise bought plus car trailer hitch and of course retrofit demands by NYS. If done properly the first time, major parts would only cost around 7K.
Additional Features-Liberal use of Molex connectors. This enables vehicle to be completely disassembled by one person down to the frame.

-forward and reverse (now, standard for later models)
