We have had a KHS Tandemania for 3 years and love it for several reasons. 1. We looked for over 10 years before we got it, and even though it is about the most inexpensive one on the market, we purchased it for its stability. We are both over 200# as well as between 5&6 " apart in height, either of us can captain or stoke, the reasoning for this is on long rides, it helps to relieve the pressure points and knee stress. It is harder for me to be the captain, but I can do it nicely, especially when the tush is tender or the pressure points on the hands are going numb. 2. I Frequently ride stoker less to my husbands office and he rides back with me, which is excellent training, because I require about twice the time in the saddle my husband does for the same results. All we have to do is use the Allen wrench to adjust the saddle for the return trip. 3. A fair amount of time we pull our 2 year old granddaughter in the trailer behind the tandem and the bike still responds beautifully. 4. Our local bike shop does excellent support on the bike, although it hasn't even been in for it's check up . 5. Saddles on a tandem will be different than on separate bikes.
Even if you have to go out of your area to try the Tandemania, it might be worth your time .
