Motor heat sink hubsink 100-250mm diameter motors
made of 6063 alloy aluminum this pair of heat sinks wraps around your motor and each one is held on with a screw and nut. each one is custom cut and is non refundable. There will be a small gap between the start and end. You will need a short phillips screw driver to assemble it. It is much easier to put these on before the wheel is spoked/laced, but they can be fed through and bent on a completed wheel as well. Please email us your hub motor diameter. If you give us the wrong diameter than the heat sink will not fit as well as it should so please measure accurately.
