and here is a comparison of 10S – 5:1 vs 4:1 vs 3:1 vs 2:1 gear ratios (25a bat limit per motor, 80a motor limit):
(if you switch to 10S, then gear it at 5:1, I believe you’ll get a significant boost – not in top speed but peak vehicle thrust, that said 2:1 @ 10S gives ~40mph top speed…)
I’m thinking a 4:1 ratio, it’ll have plenty of speed and quite a lot of torque and that means i’ll only need a 48t pulley on the wheel which should be ok
Just half read this post https://www.electric-skateboard.builders/t/gearing-ratio-for-torque/34348 seems he was trying to do bout the same as me. I think I will get the new battery and then try everything out then 3D print pulleys and see how well it does. maybe even add a cover for the wheel pulley depending on if I want to keep the higher wheel pulley
It’s close to the ground, but if the places you ride are relatively clean it should work
