I do that. Two kids, not three. And I appreciate that the bike is light. It doesn't make much sense, in a way: If I have a trailer and 150-200kg of total weight (and I have as much every couple of weeks), why should 5kg more or less matter? But it matters: The bike feels better when it's not that heavily loaded, ie. most of the time. What matters most of the time, matters.
