how the electric motors on electric bikes are made? 1

how are made the motors on electric bikes? how I can tell if one is better from another one?

Check YouTube for a motor making video.

The best way to tell a difference is to read reviews on candidates. Likely many are acceptable and a few aren't.

This is an interesting knowledge to learn. I will check youtube for available videos too.

ok I will check , but how I will know which is better than another?

but how I will know which is better than another?

If this is an engineering question suitable for eng-tips, then you might want to frame it in engineering terms.

I'd look for some bicycle forums.

Respectfully, electricpete, I suspect that our original poster is working through a language barrier.

Usually they are PM rotor motors with number of slots per pole and phase less then 1.
