The semi recumbent position of the Comfort trike provides a lower center of gravity for improved stability. The trike has an extra large seat pad together with a large backrest and a long frame and special handlebars. It really is a great trike for a big person and also can easily be modified to adjust for a smaller person with a 24-25" inseam. Specifications: 24" front wheel and 20" rear wheels. Overall length 71", width 30". Rear basket, 3 fenders, reflector kit, dual mirrors, bell, front and rear hand operated brakes and Shimano 6 speed index gears.
