Is it possible to remove a coaster brake from a preschooler's bike?

Short answer - no, not easily. Kids don't have the hand strength to use handbrakes properly, so a coaster brake is going to function better, once he gets the hang of it. He's activating the brake ...

How to make a kid's bike easier to pedal

Easing the chain tension may help, but a coaster brake itself is a good thing - it stops the kid simply back pedalling because it's easy, but doesn't propel the bike. It should be possible to change ...

Coaster brake: concave sprocket orientation

Your guess is right, it's a way of dialing chainline. Most commonly you use it in the more outboard position. It's easy to just measure front chainline and both rear chainline options and see which ...

Terminology: coaster brakes vs free wheel?

You are right, coaster brake hubs do employ the same mechanism as free-wheel hubs. The difference is, that the coaster brake limits the backwards movement of your pedals, which the pure free-wheel ...
