Conversion TimeAt least 140 hours research and buying parts, 150 hours building on and off... I really have no idea!
Conversion CostStopped counting but at least $10000CA, most of the cost was for lithium batteries, motor, motor controller and chargers.
Additional FeaturesLED tail lights and signal lights. AC cord on retractor stolen from a vacuum cleaner. Custom control breakout box for vehicle control and future upgrades. Removed one front rotor/caliper to reduce weight. 72V battery common connected to chassis via 10k resistor for safety. Stash box under the seat where the old battery compartment was.
Advice: Educate yourself about batteries, especially lithium. Had I taken the time to study up, I would have saved a lot of cash.

Thanks to EV Album for ideas gleaned off other conversions. Thanks to my father for all the welding work, beer, conceptual ideas and allowing me to make a mess of his garage. Thanks to Ian for cutting the rear sprocket; looks stock.
