Eunorau M12 to M10 Trailer Hitch Adapter, Hub Motor
Eunorau's M12 to M10 adapter threads onto a hub motor's M12 axle nut so its two-wheel hunting trailer can hitch without touching the dropout. Eunorau lists it for the DEFENDER-S, UHVO, DEFENDER, G30-CARGO, Flash and Flash AWD. It is $25.99, with free shipping to the lower 48 and US support.

What you get with this m12 to m10 adapter
A female M12 to male M10 steel adapter for the rear hub motor axle nut. Mount it on the side of the motor where the motor cable does not leave the axle center: Eunorau notes the cable cannot sit at the shaft center on the side you mount it.
The figures below are Eunorau's own, one value per row, and the fitment table repeats Eunorau's model list.
