oBikes have been described by Melburnians as clutter, litter, a nuisance and even "visual pollution".

Several pictures emerged on Friday of the infamous yellow bikes wrapped in City of Melbourne tape declaring them "illegally dumped rubbish under investigation".

A City of Melbourne spokeswoman confirmed the council had begun removing some hazardous bikes blocking footpaths.
