We discussed this issue at my local LCC group meeting (mixed sex, third of it female) last night, as we had received an email about the LCC board considering this. The consensus was, that while there might be different barriers to cycling for different groups of women (we are not just a great lump of girlz for goodness sake who all think, look and behave in the same way, you know, there are old women, younger women, women from all kinds of different ethnic and cultural groups, single women, others with tons of family responsibilities etc etc etc) the one thing that would get the largest numbers of women from all different groups on a bike would be safer roads, with less motor traffic moving around at slower speeds. The majority at our meeting thought that the LCC's Go Dutch campaign was the kind of approach that would be the most successful. Build the safe and pleasant cycleways and they will come, women, children, babies on the backs of bikes, as well as a few more men!
Interesting. Thanks for feeding back on here. Which group are you?
