They are hard to come by. They do not make them anymore and they go quickly when they do come up for sale. I have seen one in use. The family using it had it hooked up to a tandem and were very happy with it.

I have not heard of any problems with them. Search on here for Adam and you should find some threads about the trail-a-bikes. I would imagine that they are similar in feedback except the tandem of course would be more difficult to control.

Test ride the sellers set up if you can. You should be able to tell fairly quickly if the configuration will work for you. If after test riding you are unsure I would vote that you buy it. You will be able to decide if you want to keep it after putting some miles on it with your setup. If you decide to sell I think it would go fairly quickly.

Good Luck.
