I read somewhere that you could get this same effect by simply lowering the saddle on a kid's bike and avoiding the training wheels altogether. When my brother and I were learning to ride bikes, our dad insisted that training wheels were only a crutch so we weren't allowed to have them. OUCH! But we sure learned faster than the other kids. Hmmm--the sink-or-swim method of teaching kids to ride.

But, that Like-a-bike IS one snappy little piece of gear!
