Default Re: Im new please help with my common knowledge

Welcome to the forum!

Here's what you can expect roughly, speedwise, with a 26" wheel bike and a 66cc, acknowledging a 6000RPM redline:

20 with 56T
26 with 44T
32 with 36T
38 with 30T

They can be spun to 8000 and beyond, but they often won't last long unless built nice.
