I'm waiting to take delivery of an 'Industrial' grade adult tricycle with a 500lb capacity a Husky T-124C with a 3 speed case and solid tires or you may want a U.S.A. made Trailmate from Florida. https://www.trailmate.com/ These are not like the 'Cheap' junk you find on ebay or walmart.com. These can be customized by the buyer with the options you want from the list and like all trikes they can get expensive. One item not on their list was a 'Cup Holder'.
