My wife was cycling as her means of transport before me. I had a car- she didn't.

But a neighbour of mine showed an interest in cycling. Not for cycling as a sport but he saw how fit myself and a couple of other riders were and it was the fitness he wanted---not the cycling. I set a bike up for him and told him to collect it any time from the shed. Took a year before he was cajoled into taking it out and that was when another neighbour bought a bike to get fit and came out with me a few times.Cut a long story short and he took the bike out and just rode the local mup. Flat smooth route and he struggled. I took him out one evening and found he was going too fast- in the wrong gear and I bought him a pint after 5 miles. Ride back was better and he continued riding. 4 months later he bought his own bike and I have been trying to catch him ever since.

The problem is getting that first ride. Find a girl friend of hers-or yours- that rides and get her to suggest a ride one day. May take a while but you know if she does give it a try then it can go one of two ways. She will either love it once the butt ache gets overcome- or she will throw the bike at you.
