Scores of nude cyclists rolled through Sao Paulo to call attention to the bare facts: this Brazilian city is dangerous for bikers, and short on dedicated bike lanes.

Some demonstrators did a Full Monty ride while others opted for a relatively demure topless protest that was carried out in some other Brazilian cities, like Porto Alegre, and in Peru’s capital, Lima.

In Lima, protesters were demanding bike lanes and better traffic lighting.

They said they also were trying to raise awareness of cycling as a healthy and environmentally friendly mode of transport.
