Dezimal 2255 ist 8CF Hex

Dezimal 1800 ist 708 Hex. 0200 0 807, etwas trickreich

So, in short, whilst the 02002003 gives you an 800mm rolling radius, you can have a smaller effect by using 02000807 to replicate an 1800mm rolling radius, or to go back to a 2255mm (which I think is a 2.6 to 3.0 width on a 27.5” rim) you’d need to use 0200CF08

Wheel circumference is now 800mm so max speed should be around 77km/h
which the motor
will never achieve
Note: All speed values broadcasted via BLE (app!) will show values that are
approx. 1/3 of the
real value. Due to the wrong circumference.
