The Yuba Mundo is a great bike for carrying young children, and the Burley Piccolo is a great way to extend a bike so that child from 4 to 10 can help pedal.
With our Burley Piccolo, our older child is happier riding than sitting, as parents we get some extra help pedaling. It’s a win-win. Unfortunately, there’s no official way to connect the two items right now, although Yuba has hinted at official accessory for this in the future.
Here’s how we made our own attachment for the Burley Piccolo and the Yuba Mundo. It’s been working really well for us.
