According to the calculator I found with yahoo, 4500 watts = 6.032 horsepower.
750 watts = 1.005 horsepower.
It is sad that my electric leaf blower has more horsepower than a U.S. legal motorized bicycle.
Does your cycle analyst limit battery amps?
Would be cool if we could meet up and play around with our bikes.
Bump it up to 80A and see if the bike behaves differently.
btw, are you able to reprogram the controller itself through a pc?
Sounds as though you have plenty of power already, plus the advantage of instant torque.
Besides, be nice to your Batteries!
Still I don't think I would be happy with an Ebike unless I new I cold do at least a 30 Km round trip at over 60 Kph for less than $1K.
But I live in the 'bush' as we Aussies say.
In town electric is defiantly the go.
Just my opinion, but it's kinda like putting a white vinyl landau top on a Ferrari........
Now a black tire with a thin red stripe would be the shiznat!!
