This would work perfectly! But it’ll launch you with those big wheels and only 36T pulley. Maybe you have a friend that has a 3d printer or you have one yourself? You can always print wheel pulleys and test out what teeth ratio you like. They wear quicker but you can always print more or have them cut out of metal.
Here might be a usefull link:
Thanks for the advice. I do have a 3d printer, if I wanted to end up changing the ratio, would I need to get a different length belt. And how would I know what size to get?
Sometimes you would sometimes you wouldn’t. This is a helpfull tool to determine the belt lenth you need:

You can always buy a few cheap htd-5m belts from ebay in different lengths and when you find the best ratio and length buy a quality one when the ebay one breaks
