There are so many options out there. I suggest taking your time to decide what look you want. I am partial to 2 cycles because I like the looks (miniature engine). Not too fond of 4 strokes (mainly looks), as a reliable motor I'm sure there are pros and cons to each. Style of bikes is unlimited... if budget is no concern (you can buy billet wheels for $1200.) I'd go as radical as I could. Make sure that the bike you choose has some kind of suspension, either quality forks or a good seat, or both. I think it boils down to what "You" like. Old school Board Racers or radical stretches. Check out some of these bikes....http://www.firebikes.com/gallery.htm
