My 2007 edition is subtitled, "The complete guide to safe and enjoyable cycling for adults and children." It contains a chapter specifically aimed at parents. I'd say the book could be taught to kids, but it isn't written for kids.
That is probably down to Bikeability. My 2006 edition only has three references to children:
1. Watch out for them crossing the road
2. Watch out for them as "they can cycle very erratically"
3. Put them on a tandem
To return to the original assertion that "Cyclecraft is destroying UK cycling", I think that is rather too strongly put.
I do think Cyclecraft is helping to maintain cycling in the ghetto by raising a higher barrier to starting.
The joy of cycling is the "get on and go" quality coupled with the freedom it brings. It seems to me that cycling has been put into several ghettos: sports, off road, leisure & commuting rather than just being seen as a way of getting around.
The Dutch & Danes in particular seem to emphasise that cycling is basically an extension walking for most people rather than as an activity requiring special training, special clothes, special bikes etc etc.
In many ways Cyclecraft is in the same category as proposals for bike registration, compulsory bike insurance and so on in that it is a constraint to cycling rather than a promoter.
I do think the techniques described in Cyclecraft have kept cycling in the game but I don't think they can be the way forward.
What concerns me most is that Cyclecraft is often quoted as the only way to cycle and John Franklin seemingly tries to prevent segregated measures being built.
If we had the levels of cycling here seen in Denmark or Germany I for one would not be unhappy for Cyclecraft to be seen as one of the reasons for that. The thing is we don't and I don't think we will unless and until we get the infrastructure that the majority are willing to use.
