Travel bikes are great, but perhaps in your case the 2 bike solution might be the way to go provided you have secure storage for your bike when you are not there. If baggage is handled enough, eventually something will happen whether it is loss or damage. If you are traveling frequently enough, some damage may result from the simple act of packing and unpacking your bike. No idea how often you are going back and forth, so maybe I am wrong. If the airlines charge enough, that second bike could pay for itself pretty fast, it wouldn't have to be a beater. For sure, most full size bikes involve extra charges for transport, travel bikes maybe not, Once you factor in the price of a travel case, that second bike looks even better. This all hinges on you always traveling to the same place.
