You think a tandem like the Pacific one would hold up under my husband and I? Sure, my mom and sister might not weigh as much (or maybe they do, both are rather larger than I'm used to seeing them?) as my husband and I. He is 290ish at 6'2" and I am 120lbs a foot shorter.
He just got a 29"-wheeled bike (Mongoose Stat) that fits him much better, but he was extremely hard on the regular 26" wheel big-box bike. Bent the pedals, scraped them on the ground constantly, and a previous bike with a slightly untrue wheel became a bike with an unusable tacoed wheel. That was kind of funny when it happened, actually.
