I doubt adding an electric motor is gonna help u go faster down a ski slope..
I do remember there was a Hanebrink snow GPV in the winter x games back in the 90's,
DrBass had something similar in that drag strip video I have seen.
Both wouldn't qualify as a bike under UCI ruling.
Anyways, looks like he didn't break the record,

he was trying to break his own overall "aero" record, but fell short.
BTW, speed skiers are even faster,
record is 156mph
