Aosom Solo Single-Wheel Bicycle Cargo Bike Trailer
OTOH, I used a Bob Ibex for several long distance tours and while it was great, it was EXPENSIVE to take on a plane. The last time I should have just dumped it in Australia instead of paying for air freight. Now I will tour with reduced stuff (carried too much with the Bob) and maybe make better time. don't get me wrong, the Ibex was an excellent trailer, but culky for shipping.
