So, I'm wanting to attach a v belt pulley of around 6 to 8 inches in diameter to the disc brake mount on a rear wheel. I will power it using a 2.5 hp 4 stroke engine with a 5/8 shaft. I built a similar bike using a bigger engine that used chains but it was noisy and high maintenance and required a clutch. I think there is a post on here from about 14 years ago using a direct drive 49cc 4 stroke to a whizzer belt sheave, However, I've spent a long time searching, and I cannot get a whizzer belt sheave in the UK, to pay for shipping would be about 20 pounds, or dollars for you. but the ones on ebay USA, are about 100 dollars already. so I'm trying to use a jackshaft setup using belts instead, that can be tensioned to provide a 'clutch'. the other pulleys can be attached using keywayed shafts but the rear wheel is the main problem. Does anyone have an idea on how to attach a lawnmower cutting deck style v belt pulley to a rear wheel, ideally using a discbrake mount, but I'm open to other ideas. Thanks
