We're a family of five and the Apex 5 is a great way for us all to transport our bikes. Two of our bikes are for smaller kids, so they're a tighter fit, but even they get on. The rack also goes on and comes off very easily, and both the hitch lock and bike lock work perfectly. (Note about the other review: there's no need to thread the bike lock through the frame, because there's no way to remove a bike when the lock is simply pulled over the top and locked.) Overall, this is a terrific product.
