I'm getting one of these in a few months:no but I have had a few expire due to some external factors preventing me from going to do the test.
lady driving into the back of me totaling my bike.
scafholding falling over onto my parked bike writing it off.
and the crank shaft of my bike breaking and not being able to repair it for 6 years due to not being able to find a part.
but on the plus side if anyone is looking for a shaft driven bike to turn into an electric bike I have a frame for you....
