Currently set up as a bike trailer. Comes with attachments to turn it into a regular stroller or a jogging stroller. One additional harness will turn it into a tow behind hiking stroller. Can also go cross country skiing if you buy the ski pieces. Comes with an infant sling (not for use while biking) and a few other pieces for child comfort. Zipper of side windows and rollable roof allow the stroller to have good air flow on hot summer days. Has a clear rain screen and a bug screen (both shown in pictures). It can be completely open, or screened off to keep the kids bug free. All attachment pieces are included even if not shown in pictures. Includes tire covers, in use cover (not pictured), and a travel case (last photo) that airlines will check as a stroller so no charge! We have gotten lots of use out of it, but our kids are now riding beside us instead of behind us. It has a few spots of wear but no holes and is in great condition. From a pet and smoke free home.
