Having had the pleasure in training three kids how to ride a bike, forget training wheels, or taking the pedals off!
find a reasonable long grass hill - not to too steep, but steep enough to allow a kid to go down the hill riding the bike with out pedalling.
and then goto the top of the hill and let them go down the hill on the bike. Once they master the balancing part of going down, they seem to pick up the art of turning the pedals at the end of the hill to keep going (if not, explain what to do)
advantages: doesn't hurt when they fall off, gets them used to rough terrain. it becomes fun once they start to master the balancing bit
