Hi Lisa,
My husband and I used to have a Ryan recumbent tandem with USS. Ryan, which was based in Boston, was bought out by Longbikes. In any event, the bike was great! We were plenty low to the ground and could easily put our feet down flat footed. We loved the bike, but one drawback was its 10' length. We did have S&S couplers on it, but the turning radius was huge. Another drawback was how slow it was on climbs. We screamed downhill and were fairly fast on flats, but very slow on any kind of climb (even gentle ones). We ended up trading it in so we could keep up with folks in the bike club we enjoyed riding with.
