aliexpress. whoa. what a rabbit hole. It was hard to remember the mission.
My dropouts are 100mm. Currently there is a 9 inch tire, but I could try an 8 or 10 as they seem much more numerous. All in the planning stages now. I have ebike with 48volt battery, so I would like to stay at 48 volts. I found https://www.aliexpress.com/item/32837818637.html which has 95 mm space so I think it would fit. After my eyes rest, I will look some more. I thank you for the input. much appreciated.
