I, too, agree that there is no suck in riding. But, I do enjoy riding single bikes with my spouse since she got her e-assist Trek last summer. We had ridden together primarily on our tandem for the last couple of decades. Now we ride together more often than not on our single bikes. Her bike cuts off power input at 20mph but that happens only downhill with her riding style. And with our riding style. (We still enjoy the tandem, but don't ride it as frequently as before.)
