Thanks once again for your insight!
From Duff, I like the idea of assistance from a person that can slowly be phased out while still keeping the body mechanics the same.
Unfortunately, I cannot use anyone’s assistance, as I don’t have any family or friends in the vicinity and my wife can’t help me since she’s abroad visiting her family for the next three weeks. Plus, even if I had someone to assist me, I’d still prefer to practice alone.
One more… as soon as you’re ready, I would follow elpuebloUNIdo’s advice to start holding the handle.
I could try holding the saddle with my left hand, as it could perhaps help with the tilt to the left. I sometimes grab the saddle anyway; I’m practicing on a relatively narrow sidewalk (like 1.2 meters accross) with inclined grassy patch on the left and gravel soccer field on the right. There is slight (like 1") drop from the sidewalk to the field, so when I accidentally turn and head for the field, I sometimes grab the seat with my right hand to manage the drop better. However, I still feel considerably more stable with my hands flailing and tend to manage the drop without holding the saddle anyway.
For the pain I would suggest a planned dismount (PD) before a UPD happens.
I’m trying to do so, but it’s easier said than done. In case of the left tilt dismount, I am already quite decent in doing so softly; I can sometimes even bring the unicycle more or less to a standstill before stepping off its back. However vast majority of my dismounts now happens due to an unmanaged wobble, which results in a dismount where I basically land on a foot that’s in front. Sometime the speed is a bit higher also, so I have very little control over which foot I land on and how hard it will be. As I said previously, if it’s my left foot, then ouch!
It looks like you ride on the ball of your foot, that area right behind the toes. I find that on a unicycle, having the balls of my feet centered on the pedal gives less control than having the arch of the foot above it.
I have exactly the opposite feeling. It might be due to the fact that when at home, walk barefoot, so I’m accustomed to using balls of my feet for walking. I’m even considering starting to use barefoot shoes for my daily walking outside. On a bicycle I also use balls of my feet for pedaling. Even when skiing, I tend to shove my shin into the frontal part of boot and lift my heel, standing mostly on balls of my feet.
VitR, I would recommend to ditch the poles.
I will try it and see what it does. Moreover, if it’s a question of taking a break or reducing the practice time, I’d much rather use the poles. If I have to choose between just practicing 30 minutes without poles or practice 30 minutes without poles and then 30 minutes with poles, I’ll choose the latter.
I’m guessing you mount with your right foot forward and make 1/2 a rotation and then fall on your left.
I have the support (garbage can) on my left side. I mount into a dead position with my right foot being on the down pedal. After mounting I make 1/4 rotation backwards (so the pedals are horizontal with my right foot in front), wait for a sec to focus on putting my weight onto the seat and then pedal forward. Most of the time, I can do all this pretty effortlessly, not having to hold the support tightly. When I reach the end of the garbage can, I push myself off with my left arm to gain momentum. Sometimes I try just to pedal forwards without pushing, but then I tend to be more wobbly and dismount earlier.
I definitely could switch sides (I’m more or less ambidextrous, so it’s not an issue to learn things symmetrically for me), but now I’m able to land on my right leg during majority of my UPDs, except those that happen to the left tilt and some of the nastier wobble-induced ones. I’m concerned that if I switch sides now, I will have considerably less control of what leg I land on.
