where's the serial number on the path+?

[sukeiasa]

trying to register my path+ with curry tech in order to get some warranty service (found out that my shifter is not clicking right, so i only have 5 working gears instead of 8) but can't seem to find the serial number... any pointers?

Most bikes it's on the bottom bracket, like in this picture:

Could be on topside or underside.

on my Easy Motion eBike it's stamped on the center front frame, right above the fork.
