Two seats. Two sets of pedals. One steering mechanism.
This contraption is truely a compatibility test for couples that surpasses what you could get on those many of those “online dating” sites. You go through several stages on one of these things. The first, of course, it, “Hey, that looks like fun.” Next comes, “Okay, you are pedaling too (fast | slow) for me, could you (relax | pick up the pace)?” Then comes, “In order to steer this thing, we have to work together.” Then there’s a stop and a short break, followed by a pep talk by the one whose idea it wasn’t to stop and take a short break.
Then there’s communication. Deep communication unlike what was occuring before. Decisions on speed and direction are seemingly made and executed simultaneously. You turn to your mate and see she’s smiling. You realize you are too.
Riding on a side-by-side bicycle built for two on the Katy Trail near Rocheport is an education and a ton of fun at the same time.
