This week we mounted the motor on Ninja and did some testing.
The first long test was from Sugarhouse to Riverton. This was aprox 25 miles and the bike used 3 Kwh of electricity. That comes out to 120 watts per mile. This is PMG motor is very efficient. The emax scooter that I used to ride to work used 100 watts per mile and it was very slow. The ninja right now tops out at 45 mph. The countershaft sprocket is only a 12 tooth. Next week we will try a 14 tooth, then the week after that we will try a 16 tooth and evaluate all the sizes to find the most efficient size.
This week the goal is get a safety inspection and new tags.
