I just bought a new bike, trying to fit the front wheel and I got one nut off the axle, but the second is totally stuck.

Seeing as this is an open ended bolt with 1 nut on it, I have no leverage to remove the other nut. Putt ing other nut back on is no help, since that side is now unstuck, it loosens very easily. Trying to grip the bolt with pliers is unsuccessful too. Theres no where near enough friction, it just slides.
