> IME balance bikes is the greatest thing for bicycles since the safety bicycle.

Since before the safety bicycle: Balance bikes came first. Then the pedals were added -- driving the front wheel, like kids' bikes still did when I was a kid -- then the front wheel grew into the "penny-farthing", then came the safety bicycle. But the balance bike -- for adults! -- came first. Invented by a baron (Carl?) von Drais; that's why they're called "draisins" in some languages. (Which is also the name for muscle-powered rail vehicles in some languages; presumably via pedal-powered bicycles --> pedal-powered rail carts.)
