Here in London many more people ride bikes to get around as it is less harmful and more beneficial to ones health than driving a car. My sister in law, a Dutch woman, said that many orthodox women ride and it's easy to do so in modest skirts. She has been told by her rabbi that is isn't appropriate in England as the minhag here is for women not to.
I would like clarification on this. Are women allowed to ride bicycles for transport?
