I really don't know how well those would hold up against a heavy prying attack. They look pretty tough, but I have no experience with them. Sorry. I also can't tell what kind of key they use, and whether or not the key system would be easily defeated.

I am absolutely certain that I wouldn't use them as my only lock on my nice bike in a high risk area.

EDIT:
I just noticed that it has a 'Push button keyless locking convenience'.
Bad. "Convenience" always, always equates to a loss in security, at least to some degree.
