Bosch gen 4 and wheel size

[sparkle-spokes]

Prompted by an earlier post , i am now concerned to what i have done.

My Hiabike allmnt Bosch Gen 4 , came as a mullet set up 29 front 27.5 rear . At only 5ft 3inch I found this seemed to big so i changed to 27.5 on the front. This felt a lot better but after reading previous posts where someone has changing Gen 4 software to suit wheel sizes i am now concerned as I have not made any changes to software. My question is Does it Matter and what are the consequences.

The reference to mesure speed is the rear wheel I supose, so no prob.

Yep, it's when changing the size of the rear wheel where you would ideally need to tell the motor it has a smaller (or larger) wheel. And even then if you didn't tell the motor the new wheel size, it only means the speed limiter cuts in a bit earlier or later than it should do.
