also have the analog amp meter (0-500 Amps) and volt

Top Speed45 MPH (72 KPH)
Still working out how to best get higher speeds.
Something I
recently learned was to upshift when going up steep hills
generate higher torque. Would really like to get to 55 mph
and >35 mph up hills.
AccelerationGood up to 20 mph.
Range40 Miles (64 Kilometers)
Confirmed at 35 mph on relatively flat test track during 21st
Century Automotive Challenge in State College, PA (May 23,
2010). Practical range probably ~25 miles at varying
speeds and some hills.

Conversion TimeStarted project in Fall 2007 as restoration project with
intent for conversion as well. Stripped it down and it went
to body shop for welding repairs and painting in Spring
2008. Received it back in Spring of 2009. Completed
restoration and began conversion in parallel. Completed
conversion and first rides in July 2009. Upgraded to 9" motor in Fall of 2010. Still work in
progress... plan to upgrade to Netgain PulsaR controller and charger (w/ DC-DC) and J1772 plug as well as 96-120V in Spring 2013.
Conversion Cost~$5,000 for kit and extras (not including restoration
