The number of watts used by an electric motor at any moment equal the voltage supplied by a battery multiplied by the current flowing from the battery to the motor. So an ebike motor connected to a 24V battery being supplied with 10 amps of current would be powered at 24*10=240 watts.
All electric motors consume more current at startup compared to steady state. Check out the label on your fridge for example (or look at this one): the max current on the label is 2-3 times higher than the value you''d obtain from power to voltage ratio. The reason behind this lies in the properties of electric motors.
