hey, my bike is going to have 16-18 inch outer diameter tires on 8 inch wheels live front and rear axles. and a built 6.5 lifan. running a tav and 60 tooth rear sprocket. im not looking to spend a fortune on Hydraulic breaks but i want to be able to stop from the 50 or so mph the bike will do in the end. ohh scrub breaks are out of the question.
