For older kids and adults, put the seat down to the point where they can push it on the ground, and preferably have them ride it on grass. They can push the bike for a while, then start pedaling once they get the hang of balancing.

It doesn't work well for young kids because their legs aren't strong enough - it takes a lot of leg strength to pedal a bike effectively when the seat is that low. (the classic "adult on a BMX" posture, with your top knee level with your ears)

I taught a 10-year-old to ride in about an hour or two that way, using my 6yo son's bike, and the next day the 10yo and her mom were off riding all afternoon on rented bikes.
