Our friend, Russ, just sent us an email with this awesome DIY Mundo hack to add extra cargo capacity:
"Before I bought my Yuba Mundo about a year ago, I used a Bob Yak trailer when I had a lot of cargo to haul. Having the Mundo has been a big improvement on hauling capacity, flexibility, and stability. But from the start I was wondering if there might be a way to attach the Yak trailer to the Mundo to further up my hauling capacity. I started to work on that this AM, and over 30 or 40 minutes came up with two different “engineered” solutions that would have involved more or less work with metal pipes or brackets. Then I took one more close look at the Mundo and noticed the lower set of bolt-on bosses on the rear vertical support for the rear rack. I think that these bosses are used for attaching the large black plastic spoke protectors (which I don’t use). The space between the bosses’ outside edges was close to the space between the mounting dropouts on the Yak. I had already taken apart the special rear hub quick release that attaches the Yak to a regular bike’s rear axle, and had the thick, shouldered washers that the Yak dropouts rest in. I bolted these to the rack bosses—the shouldered washers are recessed and the bosses fit inside the recesses—and checked to see how close it came to fitting the Yak. Miracle of miracles, the spacing was right on! The trailer fit perfectly and the retainer clips that hold the trailer dropouts to the bike worked as well. I loaded the trailer with about 25 pounds and took it for a test ride. It handled very well; a lot more stable than it would have been on my regular bike. I replaced the stock screws on the Mundo rack with slightly longer ones and thicker washers for a more secure attachment to the rack. Total cost at the hardware store was 98 cents. I don’t think that those bosses on the Mundo rack are engineered for a heavy load, but I think that it will be reasonably safe for trailer loads of up to 40 lbs., since the load is shared between the trailer wheel and the bike attachment. All together, it makes for a very long bike/trailer set up—about 11.5 feet. So I will be using the dorky Yak safety flag to help alert drivers to the long load. I’m excited about discovering this hack and hope that others are able to use it!"
