EUNORAU M12 to M10 Trailer Hitch Adapter vs EUNORAU M12 Trailer Hitch Adapter

Both are steel Eunorau adapters that bolt onto an M12 rear hub motor nut, but they are not interchangeable. The M12 to M10 adapter is the one to get if you tow the two-wheel Hunting Trailer, since it steps the axle thread down to the M10 male fitting that trailer needs. The plain M12 adapter is a two-part mount for the one-wheel cargo trailer and fits a wider list of Eunorau models. Check your trailer's coupler and your motor's thread pitch before ordering, because the two adapters use different pitches.

• Choose the EUNORAU M12 to M10 adapter if you tow the two-wheel Hunting Trailer or any trailer with an M10 coupler on an M12 hub motor.
• Choose the EUNORAU M12 adapter if you tow the one-wheel cargo trailer and your motor has an M12 nut with 1.5 mm thread pitch.
