But the second I touch the pedals I lose control of the bike
wow you have put in a LOT of work with not much joy.
,,, I think you might have put the cart before the horse, glossed over the coasting in a straight line and raising your feet to the pedals and learning to pedal steps.
I treated my sofrider like I was eight , I had to feel what the bike was doing what it wanted to do.
All I had was page 13 ?? of the user manual and Jim Parker on YouTube.
I coasted in a straight line, wow,, heavy front end,, weird.
again I coasted, and when I first put my feet on the pedals the funny heavy front end disappeared and I was coasting on a bike.
and again,, OK maybe I leaned and swooped and started to smile.
coasted and gently I felt how the pedals turned without torque .
How it felt once I slowed down enough to apply force to the wheel.
stopped the bike , turned around , did it again.
Soon there was enough speed I coasted thru a big wide turn and managed to ease into pedaling again. whoo hoo now lets see about changing
which way I turned.
My first (cough) figure eights covered the length of the parking lot 150 - 200 feet.
But I was RIDING. now all I had to do was shrink the turning radius
shrink, shrink, try faster, try slower, try leaning, shrink shrink.
There is no reason to remember but as children we wobbled in spits and spurts and smiled cuz learning something new is fun.
we also ran into the lawn , in my case a wall , as we attempted many loose arcs we called turns,
keep your chin up (really aim for the horizon) ,,,, and smile
