Problem with Schwinn Deluxe Seven Hub
I want to motorise the Schwinn Deluxe Seven Cruiser but it has a Shimano Nexus 7 speed hub and it will need a special sprocket with special mounting plates & asbestos rubber to fit the increased radius of the clamping bolts. The bike is perfect in all other respects for a Grubee 4-stroke frame mount cos it has springer forks and a front brake. The rear brake is a coaster and the only problem is the 7 spd hub. Has anyone got a picture of what the hub on these bikes looks like or has anyone ever mounted a sprocket on one of these hubs. I reckon the outer diameter of the spoke flange is about 105mm which puts the bolt holes 55mm out from the centre as opposed to 33mm which is the distance of the bolt hole from the centre on all the standard rear sprockets.The hubs are really big and I think they look like the one shown in the picture below. I need to use the hub cos it makes up $400 of the bike price and it has the rear brake.
