Which one fits a regular bike with quick-release wheels?

The CrafTecker coupler. It is made for nutted and quick-release axles. The EUNORAU adapter only threads onto an M12 hub motor axle.

Will either work with disc brakes?

The CrafTecker coupler is explicitly not for disc brakes. The EUNORAU adapter mounts at the hub motor axle nut and states no disc brake restriction, but check clearance on your frame.

Which is better for a hub motor e-bike?

If your e-bike has an M12 rear hub motor axle and you tow an M10 trailer, the EUNORAU adapter is the correct part. For other e-bikes with standard axles, use the CrafTecker coupler.

Both are steel. The CrafTecker adds a nylon strap that can wear and should be checked. The EUNORAU adapter has no moving parts but relies on clean M12 threads.

Is the EUNORAU worth it over the CrafTecker?

Only if your axle is threaded M12. Otherwise it will not fit, and the CrafTecker is the cheaper, more universal choice.

Can I use the EUNORAU adapter with a non-Eunorau trailer?

Yes, if the trailer mounts on a male M10 fitting. Trailers with other couplers will need an adapter.

Buy the CrafTecker coupler if you have a standard bike or e-bike with a nutted or quick-release axle and no disc brakes. Buy the EUNORAU adapter only if you own a Eunorau e-bike with an M12 rear hub motor axle and a matching M10 trailer. The CrafTecker is the broader fit and holds a 5-out-of-5 rating from 4 ratings; the EUNORAU is a narrow threaded adapter rated 3 out of 5 from 2 ratings.
