Okay. I’ve never “tried” one foot riding, but I can do one foot idling.
However, i’d like to try to “extract” some details on the action and controls involved.
Here’s my hypothesis and correct me if I’m wrong.
1.) All your weight is on your seat, so pedaling must be absolutely done from 9 to 3 o’clock.
2.) Fore/aft balance control is done by:
a.) Crouching and bucking your hips, for beginners.
b.) Sitting tall and leaning fore/aft, for experts.
Fore/aft control when “normal riding” is accomplished by accel/deccel your pedaling, but with one footing that goes away.
3.) You can “cheat a little bit” with your foot on the side of the frame. I can do one foot idling, and having your foot on the frame creates an “extra lever” to tip the unicycle fore/aft.
Thus, I would be “most impressed” if anybody can do a one foot riding with the other foot “off the frame”.
4.) You must “twist your hips” to counter the twist created by the one sided pedaling action. I can’t really see this action when watching other riders. However, it might be because they are “now experts” and this action is “too subtle/controlled” to be sloppy and observable. Yet, a beginner just learning must implement this for control.
5.) I think the “best training for one footing” for a beginner is to go back to the start.
a.) Find a wall and grab it. Preferably, with a slight downhill so gravity can help minimize pedaling.
b.) See if you can control the fore/aft dynamic, with aggressive/controlled hip motion or lean
back/forwards.
c.) See if you can pedal with minimal twist.
d.) If “twisting” is unavoidable, find the solution to counter the twist with aggressive hip or shoulder
counter-twist.
I’m sure some will say I am “overthinking it”. However, I “need something to think about” to give me some control when I go into possibly hundreds/thousands of repetitions when I learn a trick. Like when I learned SIF, idling and backwards riding. Riding a unicycle(in general) and riding one footed is not a normal thing to do. My body will never just “figure it out”.
Also, when I learned to ride a unicycle. I would describe my technique as one pedal at a time balancing. Not getting into a “perfect tight rope walking/book on my head” balancing position and then slowly pedaling faster/faster. So, my goal in one foot pedaling is not to be able to just get into “perfect balance” and take off one foot. I want to be able to feel total/absolute/unquestioned control at every clock position of the crank while riding. Thus, guarantee low UPD incidents.
