Explain electric bike jargon

Voltage is measured in volts, current is measured in amps and resistance is measured in ohms.
The voltage is equivalent to the "pressure", the current (amps) is equivalent to the flow rate, and the resistance is like the "pipe size".
If you increase the volts (pressure) it makes more come out.  Increasing the voltage will make more current (amps) flow.
Electrical power is measured in watts. In an electrical system power is equal to the voltage multiplied by the current.
Power in Watts = Volts x amps
So a 40 amp continuous battery discharge capability at 50 volts = My motor is chugging 2000 watts.
1000 watts = 1 kilowatt 
My motor is running on 2 Kw
At maximum my battery can do a 60 amp burst and really my voltage is running on about 53V so 
60 amps x 53 V =  3180 watts maximum.  
When I get my cycle analyst it will be interesting to see if I ever hit 3 Kw.
So I can increase the power to the motor in two ways. Increase the voltage and increase the flow rate (current / amps).
What I really want to know is what is the maximum wattage the 4065 motor, wiring and controller can handle continuously without overheating or causing other problems, in average temperatures for an average weight man on flat terrain?  I am guessing the motor is rated around 2Kw
