Last year, we got ourselves one of the best child-related products we have ever seen: a Chariot Carriers Corsaire XL bike carriers. This might sound like marketing hype from their marketing department, but it really is a brilliantly designed product (mostly). At core, it is a carrier with two wheels, seating two children, and which can be quickly turned from a bike carrier into a regular city stroller. For us, this really means freedom! In particular, the freedom to quickly pop down town using the bike, and then not have to carry our son but rather have a decent stroller to push him around in (and to load up with shopped stuff).
