Hi All
Hope all is going well around here.

I have around 40 segways that we use for tours and such and recently found a problem with a couple of them that so far I have not been able to fix.

The Problem:
Once the segway warms up (some of them do it straight away from cold but gets worse as they warmup so it is not directly temperature related), if you try to ride it very slow, the segway feels like its "going over bumps"...
The best way i could describe this is:
Imagine your wheels are the shape of a octagon instead of a circle... as you lean forward you can feels as you are going over the edges of every step on that octagon.

What have i tried:
Replacing central console with a "known good one";
No change

Replacing Gearboxes with really good ones with brand new Polymers and couplers;
No Change

Replacing Motors
No change

The only thing I did that actually fixed one of them was to replace the CU board with another segway i had laying around for parts.

Now i would love to know if we have anyone else around here who had the same problem with their segways and fixed them...
Would love to hear about fixes for this... other than just replacing the CU boards.

Thank you
