Sure, it might be fun for a while, but what happens when the novelty wears off and you have miles to pedal before you sleep? Or when cooperation falls by the wayside? Tandems are all well and good when you're getting along, but as soon as you and your co-rider(s) get into a fight, that's it. The wheels stop turning. Or they turn more furiously. Either way, it will not be a pleasant ride. Remember, the man only told Daisy about the bicycle built for two because he couldn't afford a carriage.
