Having managed to go beyond 40mph on 65", I can't even imaging how on earth can you slow down when spinning that high.
If you gan go 40mph with a 65 gear inch ratio, surely 46mph isn't incomprehensible... In any event slowing down or stopping isn't a problem as such, even when riding brakeless, only you can do it more or less gracefully ;)
