Wheels and sprockets.

I have a 28 spoke rear wheel i think it might be 20 inches and i was wondering if a 44 tooth sprocket would work with it? Im new to this so i dont know too much. Any help would be appreciated.

ok so even though the manual says a 36 spoke rear wheel is required i can still use my 28 spoke wheel?

For one thing a 44 tooth sprocket on a 20" wheel is going to have a lot of torque but no top end at all. You'll probably top out at around 20 mph wide open. You need a 36 or even smaller on a 20" wheel.

Now I'm not 100% on this but, a 36 spoke wheel has 18 spokes per side and half of 18 is 9 and the sprockets come with 9 holes.

So following that a 28 spoke wheel divided by half is 14, half that again and you get 7. So I'm thinking you need a 7 hole sprocket or you may want to go with a hub adapter.

I don't know that it will work.

Also, you'll more than likely want to go to a 27T or 32T if it's a 20" wheel.

i think that 28 spoke wheel will work...there are 27 gaps between the spokes...you wont be grabbing a spoke between every bolt though...may be kinda week...**** give it a try,what can it hurt...new wheels are pretty cheap...let us know how it works out...i would get a smaller gear though...much smaller
