We had the budget and I only wanted to buy one tandem while not be left with desire for a new tandem in a couple years. After reading the forums here and talking to some friends, we ordered a Co-Motion last year.
I can honestly say that I wouldn’t change anything if I bought another tandem. Is it the best? Probably not, but I don’t know what would make it any better.
On handling, I’m more comfortable going down hills on the tandem than I am on my road bike because it feels so smooth and stable at speed. I does corner very well which still scares my wife a bit.
