My bike is kick only and I like it! I can run a smaller battery that is easier to hide and weighs less plus there are few more things you can get rid of out of the charging system which is always nice. The starter motor is a few lbs in itself, so you're also saving weight there. The only time I wish I had a push button is when the bike has been sitting for a while and it's cold out, then kicking it gets old, but isn't an issue once it is warmed up and started regularly.
And, for some odd reason, people think it is cool that the bike is kick only. I don't really see what the big deal is, but I'll take it!
