Work in progress. Starfire GT-4, steel wheel with 12g steel spokes, Shimano coaster hub and 22 tooth sprocket.
Went with the Sick Bike Parts engine mounts both front and rear after spending hours with various hardware store parts and being less than convinced re their reliability. The Sick mounts work good.
Yeah, these things take a whole lot more time to put together than the instructions would have you believe.
