I continue to feel greater confidence going downhill, over cracks, pinecones, etc. However, when the temperature went way, way, up, I switched back to the Townie. Why? Because the xootr does not have a cup holder, and I really wanted some ice water with us. I also wanted the option of piling the scooter on the tray, popping the young'un in the Bobike Maxi and pedaling us home post haste. So to speak.
I did not need to rescue us, but I was sure happy to have the icy cold water with us. After a moment's thought, it occurred to me that while I can't put a basket on the xootr (or at least I'm not prepared to do that yet(), I _can_ put a bell and a cupholder on it without compromising portability folded up and slung over my back.
