I’v been wondering this for a long time now. What is the fastest someone has gone on a unicycle? It doesn’t have to be on a flat, it could be on a hill or even gliding.
Just the other day I had mine going somewhere around 90. Of course, that is because it was sitting in the passenger seat of my car.
As far as I know, the top record is around 29 mph on a 36er. I’m not sure if that’s geared or not; they generally make that distinction when listing speed records for obvious reasons.
