I just joined and this looks like a great forum. I have rented a tandem bike with my partner for the last two weekends and we have had a blast. We are giving serious thought to buying one.
How do I get started? The supply of used tandems seems very limited, even in the bicycling mecca of the SF Bay Area (I've seen craigslist, http://www.tandemmag.com/classified/, and the Tandem Club of America). There is a shop that appears to specialize in tandems on the Peninsula (Bicycle Outfitter) that encourages test rides, so that might be my first stop. I do not know what size bike I need for a roadie, much less a tandem. I am 5'9" and my stoker is 5'4" Blazing Saddles in SF rents tandems (the picture shows a Burley) so that may be a good start, although it looks like an mtb and I would prefer a roadie.
Transportation looks like a problem, as well. I think I would need a rack to transport (I have a small car that will fit one bike, but definitely not a tandem). The cost appears fairly nasty, at least $500-600 or so, which is especially difficult because I don't know how long I will keep my current vehicle.
I would appreciate any pointers on how to get into the sport!
