The Chariot is a modular child carrier system that, with the addition of specific accessories, can serve as a bike trailer, regular stroller, jogging stroller, hiking carrier and cross-country ski trailer. While this might seem like the definition of overkill, it may just be the ticket for dedicated outdoor enthusiasts. I happen to know someone who owns one and he swears by it, especially when it comes time for vacations. Instead of having to choose which stroller to leave at home or whether the bike trailer will see enough use to merit the space it takes up in the car, he just packs up the Chariot and its accessories and heads for the hills.
The build quality is superb and it is full of thoughtful features such as reflective fabric for nighttime visibility and an adjustable suspension system. While a Chariot is a big investment (base models start at around $500, plus accessories) they certainly will earn their keep in a variety of situations.
