I just picked up a 60's Columbia tandem off of Craigslist. My original intent was to restore(kinda) to a ridable tandem for my wife and I. After talking with my good friend who has WAAAY more knowledge than me about bikes, he suggested I convert it into a utility bike. The reason being that our combined weight is over 450lbs and the old frame might not be up for the task.
I am basically looking for some ideas on how to successfully convert this into a viable utility bike. It will be used primarily on flat or mostly flat land, will not need to carry too much weight, and will be mostly for fun.
The options I am looking at are internal hub 3 speed or maybe a regular 7 speed with derailer in the back. (I am a newbie so my terminology im sure is off. Sorry. ) What kind of handlebars. What the best way is to get the chain all the way back to the rear wheel. And what is the best ways to attack getting baskets or bags on this.
