From Bidwels book "Secrets of El Ninja" the following data was taken from a
chart: Voltage: 48 Weight: 456 Kilowatt-hours: 4.1 (likely flooded batteries) Front # of teeth: 12 Rear # of teeth: 72 Drive Ratio: 6.0 Peak motor top speed (mph): 43 Actual top speed (mph): 43 Actual 0-30 mph (seconds): 7 Actual stop-and-go range (miles): 28
The following was a different grear ratio (with numbers in same order): 48 456 4.1 16 72 4.5 57 51 8 -- Hope this helps, Andrew
