Which one fits my bike?

Check your rear axle. If it is solid with M10 x 1.0 threads, get the Jingzan. If it is hollow with a quick-release skewer, get the Harlik. They do not substitute for each other.

Can I use the Harlik on a solid axle?

No. A quick-release hitch needs a hollow axle and skewer to clamp through. On a solid nutted axle, use a threaded adapter like the Jingzan.

The Jingzan's 304 stainless steel resists corrosion well. The Harlik's metal grade is not stated, so long-term durability is harder to judge, though its quick-release mechanism has more moving parts to wear.

Is the Jingzan strong enough for a loaded trailer?

Jingzan lists a 90 kg maximum weight recommendation. Stay within that and check that your trailer's own hitch and frame limits are not lower.

Do I need tools for the Harlik?

No. It is designed for tool-free attachment and removal, which makes switching between towing and normal riding fast.

Is the 12-pack Harlik worth it over a single hitch?

Only if you run several bikes or trailers. One bike needs one hitch, so a 12-pack is more spares than most riders use.

Jingzan 2-Pack M10 x 1.0 Bicycle Trailer Hitch Adapter for Nutted Solid Axles, 304 Stainless Steel Axle Mount Adapters with Flange Nuts vs Quick-Release Hitch for Bike Trailers And Cargo Carriers

These are not interchangeable parts. The Jingzan adapters are M10 x 1.0 threaded fittings for bikes with a solid nutted rear axle; the Harlik is a quick-release hitch for bikes with a hollow quick-release axle. Buy the Jingzan 2-pack if your rear axle is solid and threaded M10 x 1.0, and the Harlik if your bike uses a standard quick-release skewer.
