Becoming a father last December has seen my looking into all sorts of child transport systems. The obvious and urgent one to buy was our pram which is great. But then comes the question of how to move about at speed or off road? Hence I've been looking at strollers that I can jog with and rucksacks that I can carry my little princess in.
But last week I've also discovered this wonderfully designed child and adult bike (above). It's made by a Dutch company called 
Triobike. Here is their website. The front cradle detaches and becomes a push chair for two kids and the bike can then have its front wheel fitted to be ridden separately. I love such attractive, practical and (apparently) well made inventions.
