For those who require even more cargo capacity on their Boda Boda, the good people at Bikes at Work in Ames, IA have created a tow hitch to suit your needs. You'll want to contact them directly to place your order, but have a look at their solution: this hitch will work for Boda Boda Original (versions 1 & 2).
If you're looking to tow a trailer with your Boda Boda (V3), this will require a custom solution.
Of course, their trailers are second to none as well! Learn more about them on their features page.
