Super trick cycles are a lot of fun. A few weekends ago I had a go on two of them in Auckland- thanks to Tony Melton and his Mountain unicycle weekend, and also thanks to the guy who made the STCs (I’m useless with names). I would love to get one for myself, and I am surprised that there aren’t more unicyclists using them. The number of tricks possible on the STC increases greatly by using a unicycle for the front wheel as well as the back. We witnessed numerous tricks including a one footed nose wheelie face first into a wooden structure. I was set a few challenges by the STC maker - he got me to do a one footed wheelie (on the back wheel), and then got me to go from one footed riding into a wheelie. Tony’s STC has pegs on the front wheel, which is better than nothing but I think I would prefer pedals.
I think this would be very difficult on a STC given that the rear wheel is able to turn similar to the front wheel. As soon as you get a bit of speed up, the rear wheel gets the speed wobbles and starts bucking left and right. If anyone gets the chance to try a STC- go for it- you’d be surprised at how fun two wheels can be when they put the pedals in the right place!
