This is a sort of follow up to the thread re older folks and biking.
I'm 52 and I would not mind biking on a female or unisex model. As we get older it can get more difficult to swing our leg over the bike. I live in the Netherlands and the overwhelming majority models of bikes here are commuters and in two flavors - male and female.
I think it would a smart marketing move for the companies to begin offering unisex models. Any thoughts?
