Freewheel swap on fat folder

[Cal000]

I have I fat folder. Can i fit a 8speed freewheel on the motor.
Initially I wanted to swap it just so I could get an 11t high gear and while shopping for the new freewheel I saw could also get a larger lower gear. I was thinking 11-34t. I had been kicking around the idea of a larger crank wheel to help me keep up with the motor at higher speeds but did not want to mess up the low end gearing. The larger low gear will allow me to go with the larger crank with out messing up the low end gearing. I saw a 8 speed cassette that was 11-40t it would be great if this would fit then I could get an improvement in the top and bottom gears

Cassettes and freewheels are not the same. Can't interchange them.

Does the fat folder use a cassette instead of a freewheel. Would a 8speed cassette fit on the stock motor?

No, it's a freewheel. Cheap and cheaper ... that's ebiking in China.

"Can an 8 speed freewheel fit?" You'll need to consider a new shifter, then look at derailleur travel, chain clearance around the chain stay, and total width of the new freewheel and motor fitting in the frame. Going to take some serious effort and part finds.

after you buy something. all kinds of things pop up,I dropped the hammer on an 11t-28 t 7 spd freewheel then out of nowhere 11t-32T 7 spd freewheels started appearing, just make sure it is a "freewheel" rather than "cassette" when you order, they will not interchange( I am ready for combined in-hub motors and transmissions now, hope they appear soon.) Heard there was already a 5 spd in production like that have not been able to locate.

I just swapped in a 7 speed, 11-34t. The 34 is much bigger than the 28 it shipped with and I had to add a couple of links to the chain. Way more work than I planned for. Not 100% sure I’d bother doing it again.

Can someone post a link to a 11t-34t / 7sp Freewheel
I've only seen the 14-28t and 11-28t

That would be an anomaly,I am not sure if I have ever seen one, go to EBAY and type in a search, you will probably see everthing but and before you get too excited make sure it is a 'freewheel" rather than "cassette", I am beginning to see the advantages of of a "cassette" system.

That's why I asked the question.. I don't believe they are available.

Amazon- Drift Maniac e-bike freewheel 7 speeds 1128/11-34 Teeth EPOCH should produce what you need in the back. Next problem (If anyone has a solution) is to change out the front 42t ProWheel chainring- to perhaps something like a 32t? Do this sort of thing if you don't mind loosing a bit of top end to gain some lower end while trying to pedal up steeper hills.
