Adaptable to multiple uses, the Thule Chariot Multisport Trailer ensures you can bring your kid along on nearly any adventure. One attachment lets you hook it to your bike for a day of cycling, while another set lets it ride of skis for winter-time exploration. A third kit makes it work as a jogger. Of course, you can also use it as a regular stroller, complete with the requisite storage and reclining seats, and it folds up for easy transport. Available in one- and two-child models.
