18" Wheel Upgrade: not that easy...

I’ve just ordered the kick-stand, after that the next customization will probably consist in trying to arrange the fenders by heating them gently with a hair dryer…

Then I would like to see if I can put the cranck hub in a lower position to save some space for my knees. I sort of remember having seen someone on this forum that did completely invert the position of the cranck, not sure if this would require me to drill a hole for the bolt though.
