This piece of equipment can be converted into a jogging stroller as well. You can also have the kid compartment on the back in traditional bike trailer style or it comes off completely, so you can ride the bike without the kids (as if that would ever happen).
How awesome is that? I want one! Unfortuantely, the price tag does not agree with our current bear budget. Hmmm *looks around the house to see what can be sold off*
