You only need a couple of tools - all you need to do is install the front wheel, handlebars, and seatpost. To be honest, it took me longer to unpackage the bike than it took me to put it together. Only real tuning you will need to do is set the beads on the wheels by inflating them 60 to 70 psi.

I love my Goblin, best purchase I have ever made - the customer service is superior as well.
