I'm curious b/c this situation will apply to me in a few short months... Is there a technique that has been proven for training adults to learn to ride for 1st time? They don't exactly make training wheels for adults, do they?
Here's my idea. To just sit on the bike and see if the adult can propel themselves along just by moving their feet (not even pedaling) and pushing the bike along. They can use their feet as crutches by letting them hang just above the surface of the asphalt. Same as motorcyclists do just before they get enough speed to take off. Maybe if they can hold their balance long enough and often enough, pedaling will come easy. What do you think of that?
