Nothin wrong with a front drum, but I was thinkin disc on front. And the reason for drum rear is because a lot of the old style moped hubs will pretty much just bolt on, easy.
I'm glad yer happy with yer coaster, I DON"T LIKE THEM. It seems that they either don't stop you or lock up completely, no in between. If coaster brakes were all that good, why do you have any other brakes at all? I'LL TELL YOU WHY, cause coaster brakes can't be trusted, especially at 35mph.
But I still completely agree with you about the Cranbrook. It makes a great platform to start a build with. Where else can ya get a STEEL cruiser frame with STEEL rims for under $100. And thats all ANY bike is, a platform to work with. Even with the much more expensive bikes yer gonna eventually change A LOT of stuff to suit your personal wants and needs. So, in the end, all yer really buying is a frame to build on. I gave Mitch permission to steal what I've always said, (and he's using it a lot,)
IT'S YOUR BIKE, BUILD IT YOUR WAY.
