Just purchased Wald training wheels for kids bike (16" to 26"). The right side has a gear derailleur on it, which extends further than the axle. I can't put the training wheel bar on the axle since I don't have clearance.
Can this axle be extended out farther somehow?
Answer
There are better ways to learn how to ride a bike. Remove the pedals and lower the saddle so they can flat foot on the ground and push them self around and learn to steer. Then try coasting down a small slop with the feet down and then lifting the feet. Next replace the pedals and gradually raise the saddle.

What are bike gears and what do they do?

I only had one bike in life, which was a present. It was a kids bike so there was no gears I could use and stuff. But now that I have outgrown the bike, I am shopping around for a new one. I see the handlebars have this controller thing that appears to be gears or something, and I have no idea what they mean and how they work. Also, I see bikes advertised as "21-speed Bike" and etc, what does that mean?
Answer
You have led a sheltered life, haven't you.
The gears are used to make cycling easier. Higher gears are used downhill to gain speed without pedaling like mad, while the lower gears are for going uphill where you pedal faster but expend less effort.
A 21 speed bike has 21 speeds available. That one would have 7 speeds on the rear wheel and 3 on the pedal sprocket 3 x 7 =21. The 3 pedal sprocket gears are used for general speed range changing. The lowest for use in hilly country, the second for flat and the top speed range for downhill. The (7) rear wheel gears are used for uphill and downhill as I described before.
