A single other rationale they opted versus in-wheel motors was the seals, Palmer claimed. “Sealing factors within wheels is also super-complicated with all the crud and mess ground into it on a everyday foundation,” he said, summing that they mirror the proper tradeoffs “for a item that is going to be performing.”
