Burley Attached to Adams Trail a Bike Safe?
 

I'm interested in attaching our Burley D'Lite 2 seat trailer to a Adams Trail-A-Bike so my wife won't have to pull anything on family rides.

The Trail-A-bike has a safety label about the rider weight is not to exceed 85lbs. A loaded Burley and Trail-A-Bike is going to exceed this limit.

Has anyone ever experience any type of hitch failure on the Adams when doing this?

But the trail-a-bike is not carrying the Burley. The hitch load is only about 10 lb. I have seen a tandem with 8 yr old as stoker, 6 yr old on trail-a-bike and 4 yr old in trailer. This required care on corners.

No problem with weight. The trailer does not have much weight at the tongue end that attaches to the trail-a-bike (I'm estimating less than 4 pounds with my 3 y.o. and less than 6 pounds with both my 3 y.o and 4 y.o. in the trailer. I pull the trail-a-bike and trailer with my MTB or WE pull the trail-a-bike and trailer with the triplet. That is one very long chain. I hardly notice the "sway" of the trail-a-bike with the triplet.

Please make sure your brakes are really working well, and limit downhill speed since the only braking is from the bike in front of the trail-a-bike. Ride safely.

+1 to everybody said -no problem with weight, except uphill.
I frequently commute with such a "train" and have not had any issues.
Look at pictures of several road trains in this thread: http://www.bikeforums.net/showthread...=279527&page=3
