How do you remove a capnut from a toy?

We accidently put together our daughter's toy bike in the wrong order and now to fix our mistake we need to remove a capnut. We have tried prying it off with plyers and a hammer to no avail. Help?|||Try placing a cut in one side of the capnut.





Use a hack saw, file, grinder, drill or dremmel tool.


Then rip the capnut off.





Replacement capnuts can be purchased at a full service hardware like Ace and True Value.|||Did an instruction booklet come with the bike? Hopefully the instruction book has a phone number that you can call. The customer service could give you some ideas.
