I'll agree with W&S.
In my early 30's, I found myself newly married to a wonderful woman that hadn't ridden a bike in years, but was easily to persuaded to allow me to spend more on our bike than we did on our car. 2 years later, she now has 2 bikes of her own (We sold her BMX race bike to buy her a beach cruiser) and we have the tandem. It may sound backwards, but the tandem was her gateway back into cycling. I doubt she would have gotten back into it if it wasn't for a custom fit tandem with all the little touches just for her. By the way, I'm 36, she's 39.
Oh, I still enjoy the company of my shadow once in a while.
