EUNORAU M12 Thru Axle Trailer Hitch Adapter for Mid-motor Ebike

Make hauling with your e-bike easy and secure with the EUNORAU M12 → M10 Trailer Hitch Adapter. Built from rugged steel, this adapter screws directly onto your rear hub motor’s M12 axle nut, converting it to the more common M10 threading so you can attach a compatible trailer without messing up your dropout.

It’s a simple, reliable solution that lets you tow gear, racks, or camping trailers without compromising the strength or integrity of your bike.

Key Features 

• Made from durable steel for long-lasting performance

• Converts M12 rear motor axle thread to M10 — perfect for adding standard trailer hitches

• 18 mm install length fits cleanly without interfering with the bike’s dropout

• Designed to maintain your hub motor’s wiring path — install on either side, but be mindful of cable placement

• Compatible with multiple Eunorau models, including Defender-S, UHVO, G30-CARGO, and more — ideal for pairing with Eunorau’s hunting or cargo trailers

Note: The ebike trailer adapter is designed for a mid-drive ebike and attaches the trailer to your thru axle. Please select the correct adapter based on the width of your dropouts.
