I love my Kurt Kinetic Road Machine but when I am traveling I am forced to ride Spin bikes at hotels. I haven't found a good one yet. They all suck. They are hard to adjust to my correct riding position and they don't feel at all like riding outside. Get a high quality trainer and ride your own bike inside in the perfect position. I wouldn't trade the trainer for a Spin bike if they were giving them away.

You need a high quality trainer though. Don't waste money on a cheap one or you will be posting about not getting enough resistance, etc.. Fortunately the good ones only cost slightly more than the cheap ones (unlike everything else in this hobby).
