Mountain bikes on slightly technical single track is fun to ride. Taking a turn on a road bike at speeds that barely maintain grip, is fun.
Riding around a lawnchair is what my Kayak is for
I'm just pokin fun. But really, I like normal bikes. Recumbents are to the cycling world what scooters are to the motorcycle world...I'm not saying that's good, just saying its kind of a fair comparison. I might ride a recumbent, but I wouldn't buy one.
