How do I convince my girl to start riding?

I hate having to work out logistics of where I'm going to leave my bike and when to take it and when to leave it, taking it on trains that never fucking work in an attempt to travel with her, and standing shivering at stations and bus stops waiting for her to catch up when I'm riding.

Do I buy her a bike so that she's forced to take it up, or will she resent being coerced into it? The commute wouldn't be far, from Fulham to Marble Arch.

She's a bit scared of traffic but otherwise healthy and athletic - how do I make her see it's not so bad out there and a lot easier than taking public shitting transport everywhere?

I suppose it would be better to arrange a dutch city bike or something less intimidatingly masculine as a racer?

Stop waiting for her?

Might provide the motivation.
