I just picked up a 20 inch bike for my kid.

It doesn't quite fit in my car with the front wheel on and it's a little small for the trunk rack.

The wheel comes off easily enough but it's held on with normal bolts on each side.

It's is possible or terribly difficult to add a quick release to a wheel without swapping out the whole hub or anything?

This is a generic image of the wheel. The axle is solid so it would have to be replaced I'm sure.



If it's not doable of worth the effort I can get a cheap extra wrench to keep with my kid's bike gear. Not the end of the world. But if it's cheap and easy to install a thing like that, it's worth it.

Thoughts?
