Can I modify my cheap folding electric bike to pedal faster?

I have a super cheap folding electric bike (paid $179 for the whole thing). I knew when I got it that it's top speed was 10 MPH, but it didn't realize just how slow that was, and figured I could pedal too. But pedaling as fast as my legs can go only gets it slightly faster than the motor. Is there a way to be able to pedal faster? I'm thinking replace one of the cogs with a bigger one, but which? (Front or back?) I have an old huffy road bike that I can chop up for parts. It doesn't matter if it's hard to get going from a dead stop, because I have the motor.

You need a smaller rear cog or a larger front chainring. should be doable. If you have a rear coaster brake it may be hard to switch out the rear cog.

If you change the size of the chainring by 10 percent you will go 10% faster (if you pedal the same speed). Which is about one MPH in your case. a more dramatic change would be more useful.

If it's really cheap, you may not be able to change the size of the front chainring but that is what I would try first because it is easy and cheap.

Well it looks like the front chainring uses the same bolt system as the huffy, so I'll try swapping them today and see what happens. Thanks for the help!
