I'd like to see how fast a bike can go with a 3000W engine.

I'm guessing about 90-100kph on the flat. 200w gets you about 25kph so
four
times that speed requires 16 times that power (drag goes up as a square
of
speed) so 100kph should be about 3200w.
Yeah, but factor in the weight of the speakers!

I thought the speakers would be replaced by the 4hp electric motor.
