Clifford- Have you ridden a heavily loaded cargo bike? They are already a handful at times with the load "wagging the dog" to a degree. Add the hinges that pivots are and the leverage changes from what a "standard" suspension is designed to work with one might end up with a loosy, inch worming ride. besides if the load is still directly attached to the suspended wheel the shock to the load isn't much different then a hardtail with load.


For damping shock to the load it is the load that needs to be suspended. I don't off hand know of any cargo bike where the load is the suspended element. Andy
