Doesn't sound like it's the BIKES you fell out of love with.
Sounds like you got caught up with the wrong crowd.
Can you hook up with a randonneuring group near you? How about some other TE'ers? Our Seattle TE ride a couple weeks ago averaged 10 or 12 mph and our whole goal was to meet eachother and enjoy the day. (And drink beer. But that was MY goal, cuz we had lunch at the brewery that makes my favorite beer.)
Is there a route you used to like riding, that's fairly flat and pretty, with a restaurant/pub/picnic spot at a halfway point or turn-around point? Plan up a ride and post it on the local ride threads. Specify in your thread how fast you intend the ride to be, what the terrain is like, where the lunch/beer is. You may end up doing the ride alone (I did the first 5 or 6 I posted alone, but then I only gave a couple hours warning!) or you could end up meeting a bunch of new people!
