Conversion Time3 months of weekends when it wasn't raining.
Conversion Cost$2750 Cdn.(the duty sucks) and a lot of begging to the wife.
Additional FeaturesSince the motor is lighter than a battery, I mounted the motor up in the frame, using the jackshaft to change the ratios is easier than trying to find a larger rear sproket.
All motor and battery brackets were mounted in the original motor mounting holes. The frame was not modified so I do not need a frame inspection (at a cost of $1500 to check the engineering and NDT of the frame). If you can build it without modifing the main frame you should not need to have it inspected.
Great fun to ride. I have been stopped at malls, on the street and even in my driveway to ask about it. Even a guy on a new Harley asked if we can trade for a day!

Using a "Kill A Watt" meter on the charger, 2.5 kw/hr at 10 cents/kwh = 25 cents per charge (sure beats the $5 / day for me to drive my car to work)
