hmm… tandem… interesting
But, one of my colleagues in the lab has pointed out the potential flaw…with the er donor wheel we are starting out with.
“When using wheels built for solo bicycles, 630 mm (27″) or 622 mm (700c) wheels are likely to be unsatisfactory for tandem use. Mountain-bike wheels in the normal 559 mm (26″) size will give good service, if they are of good quality. If you are using three-speeds, the better older 590 mm (26 x 1 3/8) wheels can also give good service in light duty.”
Says Sheldon Brown.
What about a unicycle? That’s an interesting beast too…
