I'd be interested in this too. I currently cycle with my toddler to nursery and back and have a really cheap, crappy and heavy bike which I need to replace before winter sets in as I don't trust it to get through any sort of challenging weather.
One thing I would say about the Bobbin and Duchess bikes is although they look great and are comfortable, they tend to be a lot heavier than most bikes. I used to have a similar bike and there's no way I'd put my toddler on the back of it, plus a basket with all our stuff - I'm just not fit enough to move that kind of weight!!
My wish list for a new bike now is for it to be super light but sturdy and to be relatively upright for comfort.
