We used a rack for a 700c wheel, which makes it a bit high, but basically all of the main rack makers also sell smaller racks for smaller wheel sizes, or as stated for recumbents. We also zip tied 2 water bottle mounts up on the boom because all of the normal places are too small to hold a water bottle mount. My son has now grown to a seat on the tandem and his older brother has cast off and is now on his own wheels when we tour so sadly the Piccolo has been hanging unused in the garage lately. It was a fine solution for several years however. It is plenty stout to handle a rack and a moderate load. I would not put more than about 20 pounds or so on it though as it will give your little one more weight to throw you around with if they are prone to that. The stout frame of our tandem and the weight of 2 riders helped us resist any wagging the little one caused, but you likely will be more influenced by that on a single bike.
