Motorized bikes are totally fun. I like to watch people look at my bike and just trip off it. Honestly, I will be eating lunch and watching my bike while people stare at it for like 10 minutes like my bike is gods answer to their legislation it is 66cc though not 48 cc just kidding. I am going to build a new fixie. It's just better in my opinion to fly on peddle power than be scared of a gasoline engine. And that is how I ride, in fear of a drive train failure... I have had too many drive trains and derailers explode in mid flight, engine or peddle power. It's enough to make one think twice about peddling as hard as one can.
