P06: Outside Wheel diameter. default is 22 or 23inches

If speed is not accurate adjust wheel size

P07: Speed gauge magnetic steel number: range:1-100.

This parameter is related to the meter display speed and needs to be entered correctly; If it is an ordinary hub motor, direct input of magnetic steel.

If it is a high-speed motor, it is also necessary to calculate the deceleration ratio, and the input data = the number of magnetic steel x deceleration ratio.

For example: number of motor magnets 20, deceleration ratio 4.3: input date is:86 = 20x4.3
