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.
-anti-vibration cowl upgrade (now, standard for later models)
-forward and reverse (now, standard for later models)
-seat slider
-upgraded high-capacity DC-DC converter
-battery management system(s) (for Lead & lithium systems)
-Grid charge or solar charge (using separate 200W solar array)
-Custom 12V wire harness
-Transparent dashboard with 3 accessory switches
-Improved rear fender to eliminate water spatter
LITHIUM PACK:On-board charger, BMS
LEAD ACID PACK:external charging system, Powercheq modules, External 200W solar charger
