Proper Gearing for ME-1003
Iv'e got my bike road worthy:
81 KZ440 LTD
ME-1003 (72V, 200 AMP, 3050 RPM)
6 Sealed Lead Acid 26ma batteries
Gear ration 10T Front, 45T Rear (stock)
After some calculations, I see I should do about 50-55 mph top speed
I can only get up to about 38
What is the reason I am only getting 2200 RPM out of my motor?
Poor gear ratio?
Improper wheel/engine alignment?
Un-programmed controller? (waiting on the cable)
Did you get the controller new? Of so, it should be ok...but possible the speed is turned down.
-batteries aren't charged
-throttle isn't going full on
-there's some added load (something rubbing, or going up hill)
You should probably go to an 11 front...10 is kinda small. That RPM is unloaded...with a load it will be lower.
