No special tools used. The spokes are already assembled, and there are bits of plastic holding the brakes open. Just don't remove them until you are ready to attach the wheel. In fact, thinking back, and looking at photos of the bike out of the crate, the rear wheel is already attached! I cannot remember if I had to put the caliper on, however. I think my forgetfulness is due to the fact that I have removed my rear wheel to get the new sprocket on a week or so after assembly.

Anyway--don't remove the plastic holding the brake open, and don't squeeze it, either! Pour the acid into the battery and get that on the slow charge (okay, you will need access to a battery charger which is a 'special' tool that not everyone possesses, lol)
