Considerably cheaper than Tern GSD. Performance Line 65nm is still great motor for hauling heavy loads just not as powerful as cargo motor on GSD. They also have ST (short tail) version which is equivelant to HSD with 10spd PerformanceLine which is lot cheaper than HSD's which come with IGH. Entry level HSD is 9spd 50NM activeline plus which is bit weak for light weight cargo bike.
