I've used those things, but they are crap. They only hold radiators because they are used over a large surface area and the pipework is holding the radiator up. I would not trust a TV to them either, seeing as they won't hold a toilet roll holder or a towel rail to my bathroom walls properly.
I certainly wouldn't be happy hanging bikes off them. Over such a small load area, if they don't fail the plasterboard will.

Anyway, I have a buyer, so...
