EUNORAU M12 Trailer Hitch Adapter vs Jingzan M10 x 1.0 Trailer Hitch Adapter

These adapters are not interchangeable: the EUNORAU M12 is built for Eunorau hub-motor ebikes with an M12 nut, while the Jingzan is a generic M10 x 1.0 adapter for nutted solid rear axles. Buy the EUNORAU if you own a listed Eunorau model and tow the EUNORAU one-wheel cargo trailer; buy the Jingzan if your bike has an M10 x 1.0 solid axle and you need a standard trailer mount. The EUNORAU is a single-purpose steel part with a narrow fit list; the Jingzan is stainless steel, comes as a two-pack with flange nuts, and fits a much wider range of ordinary bikes.

• Choose the EUNORAU M12 if you ride a listed Eunorau hub-motor model (DEFENDER-S, FAT-AWD, Flash, G30-CARGO, UHVO, DEFENDER) and tow the EUNORAU one-wheel cargo trailer.
• Choose the Jingzan M10 if your bike has an M10 x 1.0 solid rear axle and you want a stainless two-pack with matching flange nuts for a standard trailer.
