I am thinking about going ahead and making this a single speed, losing the fenders, going with different handle bars and hopefully fixing up the saddles and keeping them. we are not planning on doing long distance stuff this is just going to be for cruising around so I dont think a three speed v. a single speed is going to be a huge difference. I would also have to ad a brake since I would be losing the coaster brake. It seems like the bottom brackets are rusted to much to save, but I dont know if they will be a standard bottom bracket or if they make weird tandem bottom brackets or anything.
