You will get it!!!
I can sense determination in you.
-you’ve “ditched” the electronic pseudo unicycles.
-you’ve done the research(too bad “most of us” riders “can’t teach”)
-you bought a 26"
-you got rid of the 26"
-you got a 20"
Sounds like what I went through. Whoever made up that rule “just takes 15 hrs”. Probably “you people” who used to ride when they were 8 or 10 years old. (yes, I’m very jealous…but mostly angry at their useless advice)
It took me about 2 months riding everyday totaling 70+ hrs. I also, threw my 1st unicycle(24") into a trash dumpster after wasting 30hrs of getting nowhere. Re-adjusting that stupid wimpy seatpost clamp, and re-tightening that crappy/non-standard cotterless pedals. Then, I finally got a solid 20" torker, and did a few “opposite” things. Finally…Success!
1.) Maintain solid heavy “pedal tension”. Unlike riding a normal bicycle where you push down(front pedal) and relax(back pedal), you must keep pressure on the “back pedal”. Otherwise, the pedaling speeds up = you fall off.
2.) A.B.L.F. “Always Be Leaning Forwards” But, first gear up. Safety gloves, elbow pads, helmets, (even a bmx or motorcycle crash vest). Then starting leaning forwards. I’m an old skateboarder who used to skate in bowls, when you drop into the bowl it feels like you are “falling down/forwards”. That’s when I knew I finally “got it” on the unicycle. Same kind of feeling. Don’t fall behind the unicycle. Fall forwards. You need to feel it. Get used to the feeling.
(If I could go back in time it would have cut 55 hrs of learning…then I could brag,…yeah…15 hrs…me too!!!)
3.) Key. Get the balance right! Leaning forwards + pedal speed = riding. It’s just the pedaling “quality”. Always, maintain the tension in both pedals when pedaling. Fast pedaling = your body will rock back and unicycle goes forward.(then it shoots in front of you) Slower pedaling = your body will rock forwards and unicycle get’s behind you.(then it shoots behind you) Also, if you just freeze your legs you will lean forwards(quickly), which you might need in a pinch. Get the balance right.
4.) Last tip. Do not sit up straight, but rather hunch your upper body forwards. This is an “additional control” to the forward lean dynamic. Sitting tall and looking at a distant object in front of you bullshit, is for we you get better.
5.) Almost forgot. Pinch your thighs together on the saddle. This is your lateral control or “twisting unicycle” control. An absolute must.
So give it a try. Or even do the opposite. Experiment. You’ve obviously been trying the standard unicycle expert advice tips to no avail.
Good luck.
