Soma has a pair of cargo bikes in the works. The “Tradesman” is their modern take on the traditional English baker bike. It takes a 26” wheel in back and a 20” up front. Maximum capacity on the platform is around 50 lbs. It’ll be available as a frameset in mid-November for $600 retail.
The “Pick Up Artist” is a longer, front loader with linkage steering. It has a much higher carrying capacity of up to 150-200 lbs. Like the Tradesman, it takes 26”/20” wheels. Soma has not yet committed to manufacturing this one, but I’d love to see it come to market. If you like the looks of this bike, consider dropping them a note to encourage them to make it available.
