I bought a carrier for more comfortable long-distance riding (Granfondo and visits).
When folded in two rows, people couldn't sit, so I attached the carrier.
Tow ball work is essential (13 pin 50mm).

It is a 2-stage Tool Outpace, officially certified by the Ministry of Land, Infrastructure and Transport in September 2025.
KATMO registration is possible, and it is no longer an illegal attachment.
I didn't need Epos just for loading. Loading racks or tool holders are much better with Epos.
E-bike riders should get Epos.
(Weight limit per unit is 15kg. Epos is 30kg per unit)
I also installed an additional license plate.
Get a 'Confirmation of External Device Registration Number Plate Issuance' from the district office
and receive an additional license plate for 26,000 won.
(Before and after installation photos are required.)
It seems convenient that it can be folded in parking mode like this.
Installation takes less than a minute, including swan neck fastening after a few practices.
It seems like the emergency brake should be turned off..
Every time I reverse... it grabs my neck once with a sudden brake...ㅠㅠ
