ELECTRIC BIKE POWER CALCULATOR

This calculator allows to estimate what should be the minimum drive parameters to obtain the assumed speed and range of electric bike.

Speed:		Mph
Range at one battery charging:		mi
Total weight of vehicle:		ibs - more information
Nominal voltage of drive:		V

SUGGESTION: The indicated nominal voltage of drive may turn out to be too low to obtain the assumed speed mph, thus we recommend to apply nominal voltage from: V

Other travel parameters are set for typical electric bike, that is: Rolling resistance: 0.013; Aerodynamics coefficient: 0.9; Face surface: 0.46m²

Suggested minimum parameters of drive:

Engine power:		W
Energy accumulated in battery:		Wh
Battery capacity		Ah - more information

If you have already estimated what should be the parameters of the drive you are interested in, you may try to search for it in our drive catalog

Dear Ricky

Here you have calculation to reach 140km/h:
http://www.electricbikesimulator.com/calculator.php?language=en&speed=140&range=100&weight=400&voltage=12

I think you need engine with a motor rated at a minimum of 20kW
Exact calculations are complex. In the comments under the simulator you have an exact formula for calculating rolling and air resistance.

Dear Bartek

How to calculate the Power of the motor?

As i am planning to increase the speed of the motorcycle to 80 to 140kmph.

So kindly explain how to calculate.

This calculator does not matter the size of the wheel.
Smaller wheel - lower speed - lower power required

Watt hr / km - This parameter is shown in the simulator in the lower window.

In free time I will try to update the calculator so that the coefficients of resistance can be changed and to show the energy consumption wh / km

Dear Bartek

How to calculate watt hr / km ? Including air drag, rolling resistance etc.

Total weight 500kgs

Maybe a stupid question? But does your wheel size actually cares, cause in my head it doesn't. It only needs more RPM no reach te desired top speed. Am I right or wrong?

RIM SIMULATION

By changing the size of the rim you can see how the same engine will behave in different wheel sizes.
