My tyke is going to be of age to "portage" soon and I just don't have room for another bike outside of the road bike I am saving for and my current Steamroller. If you were me, living in a largely flat city (NY), would you consider hooking a seat up to a fg bike? The only safety issue I see is the increased difficulty of unweighting the back wheel, but I will of course not be skidding and of course will use a front brake. Provided I ride like my child's life depends on it, do you guys see any problems with this combination?
