You need to realize that cargo is meant to be carried with a trailer, and something that gets you there faster and more efficiently without having a stupid suiside attachment to one side of the axle
These idiots and their bags need to get a real trailer and put their food in the back and stop running around with their "Square" scanners....their app happy craze has no value for the rider or the long hours
They don't pay shit and can't haul shit either
They saw the couriers carrying goods on single speeds and thought "Hey I can put them outta business"
That bike friendly front....?
Cmon they are cutthroat
This is the way of carrying up to 500 Kgs on a bike.
If you have hills to deal with get a SRAM Dual Drive on the rear for 81 speeds of variance.
