Nothing wrong with a cruiser, although I'd want a few gears. One of the fellows in our local night group rides is 70-something years young, a stronger rider than I am (I'm 58), and he has no trouble cruising on his Electra and similar casual bikes on our 12-16 mph group rides of 10-15 miles, including some fair hills (as Texas goes). And when he's riding his "serious" bikes I can't keep up with him on hills.
