It’s a difference between cheap systems as well. There are two main options in the Bafang Hub drive controllers for cheap E-bikes. One applies max power up to a given speed and the other applies constant Amperage for a given level of assist.
The constant amperage models are superior as it more closely simulates the Tourque based mid drive motors. There are some controller / displays that are set up to do both so if you google the manual for the display you have there may be settings available to change that aren’t locked down by the manufacturer.
