Hey i've been looking into trying to find a rear sprocket bracket that would be more easier to work on should i ever need to get into repairs requiring the rear sprocket to come off. I been looking into one that looks like this (CB-110 Hub Adapter and Sprocket ( Worksman Edition)) but so far i can only find one that only fits coaster bikes. I have a 26'' raliegh mountain bike with my 80cc engine kit mounted on to, is it even possible to get one of these kinds of brackets for my type of bike?
