Hi Everyone! I'm a new RadMini Step-Thru 2 owner & work commuter! I love it--- love love love. But my biggest fear whenever I ride is a flat tire, so I'd like to practice a repair before I'm actually in need of one. I've watched Rad's Change-a-Flat video, and a few others. I'm not handy at all, but I'm ready to try!

Unfortunately.... I can't loosen the Axle Nut on the rear tire! It's on TIGHT. The bike is only 2 weeks old, they must have used Hulk Hogan to tighten this thing at the factory. Eek.

My (probably silly) Question:  Can I use WD-40 to loosen the nut?

If I use WD-40, will I ever get the tire back on and tight, or because of the grease on the lug nut threads, will it be super wobbly? I don't want the tire to come off when I'm riding down one of the big hills I have to tackle to get to work. 

Or... is there a better way to loosen an Axle nut?

Thank you in advance for any help/advice!

Jen
