Oh boy ... I see the appeal. And as hard as it might be to pass it up, that is what I would do. The hi-ten (steel) fork is the first strike. Unknown is the dropout spacing of the rear axle. Tandem spec is 145mm. I would even say 140mm would get this one over the finish line but my guess is it might be 135mm (MTB) because with that gearing and those tires the designers aren't thinking there will be much stress on the running gear. New, these bikes are $899. That is just astounding and not in a good way. The problem is, for the $400 ask for this particular bike an older (but not too old) Burley Samba could be found and it would be 5x this particular model in value. A Trek T900 could easily be found for $400 and with not a lot of work could be made every bit as badass looking as the Polygon but with a fair amount more quality underneath.
