Crystalyte 5403
In our last Crystalyte shipment we brought it some of the very large 5400 series Crystalyte motors at the request of several customers. These motors are tanks, designed for 150mm rear dropouts, and their 13.5kg (27lb) mass means they can handle significant power levels for long periods of time before overheating.
The hubs are on our simulator, and have been modeled in CAD as well. We only have a handful left from this order available both independently or as part of a kit with a 40A 72V controller.
