I have a Schwinn cruiser from the 90s with a Shimano 333 3 speed hub. I have found that the only source for parts is eBay and it is pretty sketchy.
The bike will be ridden by myself (I weigh over 250 lbs.) on mostly flat pavement, so I am looking for durability, easy of maintenance, parts availability and modest cost. I would prefer a coaster brake.
Any opinions on more than 3 speeds ?
