My wife and I test drove a Paso Doble Friday. We parked our ancient Schwinn Twinn Sport and had a nice 25 mile test ride. My stoker didn't notice much difference but I sure did.
It was nice having more than 10 gears to chose from. I was able to accellerate nicely as well able to stop in a reasonable distance.
Now if I could just get (my wife) past the price of a new bike.
