That's certainly your choice - no one's forcing you to use them and if you feel uncomfortable or unsafe without a helmet - and can't be arsed to carry one around, - then it's clearly not for you.
Seeing as there is no legal compulsion to wear a helmet when cycling, I see no reason why the bike hire scheme should be burdened with such a restriction too.
i do think it is a shame that cycling helmets aren't available, practical considerations aside. i thought the scheme was intended to be attractive to tourists, not just locals with knowledge of the roads.
