I have a similar issue. All I can say, is the more you try and [s]force[/s] persuade them, the more it tends to put them off.

If someone doesn't want to do something, probably best to leave it?

Besides - bike time is my time. Not sure I want to share it with 'er indoors. It's the best bit of peace and quiet I get! (and she gets as well I'm sure!) ;D
