Please allow me to rant about this "product" for just a moment.
In a younger life, I spent 5 years working in a bicycle shop. In 5 years, i never once failed to train a child how to become proficient at riding a bicycle, without training wheels, in under 15 minutes.
Buffy and Kyle would stroll into the shop looking for a ride for their little darling. I treated them with tough love. The parents, that is. "Put training wheels on my child's new bike."
"No. Allow me a few moments of time out in the parking lot with your kid and his/her new bike. You stay in here and watch through the window, and don't come out until I say so."
"But... but... but..."
"I said shut your pie hole and stay inside. Little Johnny/Janie will be just fine."
And lo and behold, little Johnny/Janie was just fine, and once they discovered how their sense of balance worked, which takes less than a couple minutes with young kids, they were cruising around, looking at where they wanted to go (sound familiar, all you motorcyclists?), starting, stopping, and handling their new machine like a little Lance Armstrong. It was a beautiful thing. Then I'd tell Mom and Dad to drive immediately to the biggest quiet parking lot in their neighborhood and spend the afternoon reinforcing and practicing the new skills the kid just learned, so the muscle memory aspects of the training would take hold fast and stay in place.
If a child needs training wheels, the child is not yet physically developed to the point of safely being on a bicycle. Such is life, come back next summer and we'll try again. We'd like to make sure your child is not needlessly put in danger if we can help it. If a parent came into the shop for a second set of training wheels because the first pair was worn out, then I called the cops and child protective services at had the parent charged for the crime of being unable to teach a child anything. (Ever see a kid slowly riding a bike down a sidewalk, leaning to the side, riding on 3 wheels? That's not what they are for. A sign of an incompetent parent.) By the way, regardless of how big or strong or smart a child is, I never felt that kids younger than about 6-7 years old truly had what it takes to safely ride a bicycle, and my experience supported this theory every time the parents of a 4-5 year old brought their kids in to try out a bike. The mental maturity just wasn't there. (By the way, never, ever get a bicycle for young kids that have hand brakes or multiple gears that need shifting- they simply don't have the hand size, strength or coordination to operate such things. And those parts are usually of such low quality even an adult has trouble actuating those controls.) With kids younger than that age (~6-7), the concepts and skills necessary to successfully operate a piece of mechanized equipment is just a bit beyond their developed skill level, not to mention the maturity needed to take care of it, and by that I mean not laying it on the ground behind Mom's car, etc.
Phew. Where did that come from? Oh, well, thanks for letting me blow some long pent up steam.
