The Burley Piccolo is the most stable trailer ride for your kiddo, the anchor point on the Moose Rack is rock solid and avoids the tippy feeling with other brands/models. More info in the web link. Your child learns how to use gears while attached to your bike, and before long they are pushing you up the hills. 2 Moose Racks included -- one for your bike and one for the bike enthusiast grandparent. Piccolo and Moose Racks pretty much like new, used for one child. New price would be $400 for the Piccolo + $70 for the extra Moose Rack.
