ConwayBob,
Welcome to the site.
Not much to put the DF together from the crate. Install handlebars, forward controls, battery, drain and add motor oil, adjust chain,etc.

If you have any motorcycle maintenance experience you should be fine but it sounds like your local China bike dealer will work on the bike if needed.

You could have the DF drop shipped at your dealer and they could put it together for their $65 an hour rate.
