Looks like we're getting into riding bikes as a family activity. We're all decked out with two hybrids, two 16" bikes, and a trailer for the smallest member. Now what do I do about getting these things hauled around?? Thinking ahead, we could be a 5 bike family within a year or so. The two 16" bikers will soon be 20" bikers..

I need some input from those out there about how to haul all these bikes! I would prefer a hitch mounted setup vs roof as we have a minivan and we're a tad veritically challenged..

Thanks ahead of time,
Brian
