My top tip on building a bobber is to get an old bike and bob that as you will be buying a brand new bike are you really wanting to chop the frame, fuck up the paint work etc etc? i know a bobber is all about your own personal preferance and that but to me a bobber needs to look ugly yet sexy, finding things down the scrappy and making it into a motorcycle part and so on.
Dont get me wrong the Bolt is a sexy looking bike and will make a very nice bob/chop but its going to take a deep set of pockets to keep it looking nice, where as the old dirty bobber look can be done on a poor mans budget.
Good luck and im def looking out for this one
