Did Burley get rid of the center strap for a single child on the newer model? A saw a January 2015 review of the D'Lite which features the center strap in the case you want to use it with a single child. This one does not seem to have it. I went as far as driving to a store that has it on display and could not locate the strap. This was the only reason I was considering the extra expense of the D'Lite. My youngest is not old enough to ride on bike mode yet, but the oldest is so, she will be riding alone for a while and I want her on the center. Next step is to read the manual of the newer model, maybe it has something I couldn't find.
