Don't Buy a Tango Tandem.
Avoid the Schwinn Tango Tandem.
My fiancee and I bought one of these to try out tandeming. I'm a veteran, and she's a newbie.
Anyhow, Its a $600 tandem, that looks great, but is very poorly made.
Notice that idler on the bottom, we had problems with ours in the first 20 miles. It got dirty, then seized, causing our timing chain to always come off. I cleaned it, moved it back into position, but it kept getting dirty, and moving on its own accord.
Pedals grind, must be because the bearings are shot-out-of-factory. Everything made a grinding noise, parts rubbing etc.
Its not meant for any kind or scheduled riding. Just a once in a great while, weekend excursion of less then 10 miles.
