Most people have not seen me towing with the folding bicycle. This gets alot of attention. I wouldn't recommend this rig for every day use, but it is great for picking up a bicycle from the bike shop. The short wheel base is perhaps less suitable for towing, but it has an element of convenience, and sure gets attention.
The bicycle fits inside the trailer. I plan to tow it home with a large bike tonight. I'm planning to secure the gear w/ a 4 hook bungee net. The bike might fit better with the detachable pedals off. I put weight plates inside for extra load. With the bike & gear, it will be 70 pounds of cargo. No problem. 70 pounds of cargo, plus the trailer and other bicycle is well over 100 pounds. Bigger workout.
Down the road, it would likely be useful to have a trailer that can be towed by a bicycle or a car. Nice thing about this trailer, like the bicycle, it is also lightweight, and it folds up.
