Wheelbase essentially. The handling is a lot more agile, tight u turns, maneurverability, feels good having the front wheel closer. Super easy to pop the front wheel up over a curb while riding, and lift the back too, where as the cargo is much longer and sort of required the wheel to do most of the work.
It also has the same capacity as a cargo because you can use a cargo rack and extender bar like i did.
The Cargo feels really long, and turning is slower (less reactive) at slow speeds, due to the wheelbase. Its probs more stable at speed, and the front wheel position makes it less likely to tip forwards if loaded heavily in front of the wheel. But if ur hauling something that big, uve probs got buddies to help getting it on and off, and you wont be flying at speeds that require more stability than what the mini max's wheelbase already offers.
But what also had a lot to say was Jimmi had this one in the basement with sliding dropouts, allowing for lots more tire clearance.
