Riding bicycles may be ecologically sound but not in New York’s strictly Orthodox enclave of Williamsburg.

Chasidic residents successfully lobbied for the removal of a bike lane, citing parking problems and reportedly the invasion of scantily-clad riders.

In response, two-wheeled objectors had planned a protest last Saturday with a topless ride through the area.

But providence, and the weather, intervened: the downturn in temperatures forced the stripped protesters to cover up.

Is there a prayer for frost?
