Maybe it's because I love mopeds, but my pet peeve is the bikes that are as big as small cars.
I mean, really. Have you seen some of these monsters? If you fell over, you'd need 2 people just to stand your bike up.
How big can you make a 2 wheeled vehicle before it gets stupid?
People can ride and enjoy whatever they want, but I think some of those large bikes are just plain foolish.
Sometimes, "Less is More".
