I can't see the attraction in unicycling myself, the movements seem stunted because you can't free wheel. How ever i will say that its much harder to be good on a unicycle than a scooter, i tried a unicycle its bloody tricky. i tried a scooter and within 15 mins i was doing little 180's off curbs. you also look like a massive tit if you're on a scooter and you're over 16 or 5'6"
Commuters on scooters?...honestly
