Why do many kids bicycles' pedals not rotate freely in reverse direction?

I have to buy a kids bicycle (20"). I noticed that pedals in many of these bicycles do not rotate freely in reverse direction. Is that a feature or a bug? It's useful to have them rotate freely so that you can easily bring to them to starting position when you're just starting your ride.


Answer
As others have noted that style of brake is known as a 'coaster' brake and is very common with bicycles designed for younger kids. It operates much like a drum brake in that when operated by pedalling backwards small internal plates are pressed against the internal shell of the rear hub. Kids bicycles have coaster brakes because smaller children for the most part do not have enough hand strength or have not developed enough coordination to operate a hand brake that you would see on most adult or larger kids bikes. Yet they do need to be able to stop, hence the coaster brake. On larger kids bikes -- with 20" wheels or BMX style frames -- you will often see a combination of a front hand brake with a coaster brake. This is sort of an inbetween bike, if you will, designed to allow the developement of the hand strength and coordination necessary to operate a normal hand brake.

How old were your kids when they started riding a bike?

I would love for my little one to ride a tricycle when we go for walks in the neighborhood, but she is too young. How old were yours when they got the concept of pedaling?
Thanks, y'all. Looks like we have a few more months before we should try again.



Answer
My son starting riding a bicycle at 2 years old - no training wheels. The other kids rode a tricycle until about 5 years old. Each one learned how to ride a trike in their own way, but my youngest got a tricycle that had a pole in the back that an adult could push to help them move the bike. All she had to do at first is keep her feet on the pedals. This was a tremendous training aid, and also helped when the little one was too tired to pedal all the way home.
