How can I take the axle out of my Kickside?

wrap a rubber band around it so it wont damage and grab pliers and turn them just like taking the halfs apart and it should come off

If you need to keep it in tact, do the rubber band thing pollo said and if you can get an allen wrench (hex screw thing) and do both if you can. If you don’t need to save it, just grab with pliers. Either way, twist.

I just use the allen wrench.

I think a tissue is more effective than a rubber band, but you have to make sure you have a firm grip on the axle.

If you can, though, an alan wrench is best.

Take a cloth, and unscrew it with a pliers or something like that. You could clean your axle while you’re at it too.
