I used training wheels in the beginning with a strap, then got rid off the strap, then got rid off the training wheels. I practiced in a tennis court, hanging to the fence wall for balance with all the safety gear. That is helmet, wrist guards, shin pads, knee pads.
When putting your foot on the pedal, think of putting your foot on a foam cup without crushing it. Someone here said this, not me, but that was a good analogy. At some point in the beginning you want to give up because it is too hard to balance no matter how much you put effort in it. but DON'T. If we all can do it, you can do it. It's like learning to ride the bicycle all over again. It's hard at first then it's a second nature.
