Can a trailer be connected to the trike?
Yes. Under the seat is welded a little 3 inch bar. (You should be able to see this bar in the above pictures.) The bar is hollow and is probably meant to be used when connecting a second set of passengers to the first. Fortunately, the manufacturer had the where-with-all to make this bar the same size as the hitching post on a regular bike. Thus, you can connect a typical trailer or carrage to the Ricksycle.
