That's a lot of information for the marketing agencies to target us cyclists!
I can speak to some of the info: you pretty much need to be single or have older kids to really get into cycling because you cannot go long distances or commit to multi-day cycling trips with young children. Yes, you can tow them or have them on a tandem but they have to be as into as you - I would not tow a child for 200 km on Le P'tit Train du Nord trail! I can only speak to my personal experience, but when I attempt to go out on an interesting ride, my 9 year old son wants to stop everywhere and look at everything. It never amounts to a long ride. But it is a different ride - we enjoy the journey, however short it is, and I cherish those moments. However, I do look forward to the day when he wants to do the long trips with us.
Here in Quebec, with the route verte, I am not surprised that cyclists are over-represented - we have (and are building more and more) a great infratstructure for cyclists. This year Montreal introduced the Bixi bike taxi system around the city, and you can see how the bike paths have improved and expanded at the same time.
Get on your bikes and ride!
