After ordering on November 5th, received on November 26th in the morning. It seems like a new seller and I ordered with some doubt as it might be a fraudulent company selling at low prices on Ali recently, but I received it today. I just received it and opened the lid before going to work, and I will assemble it tonight.
I developed a hobby with electric bicycles and have recently expanded my interests to include electric scooters. This is my third purchase, but this time there was no request for customs duty payment and no Kyungdong delivery fee either. It seemed strange, but I found out that the Kyungdong delivery fee was prepaid. I was so moved that I was embarrassed^^
I will post additional feedback after driving after assembly.

There are some difficulties in assembly.
It would be great if the manual was detailed. A detailed explanation is especially needed when assembling the caster wheels.
After assembling everything and doing a test run, it went well. I'm glad and happy about that.

For the price range, I am satisfied... The battery capacity is large and I like the cushioning too~
I will try it a bit more and leave a review~~

Recommended. It works well. The only issue is that the front wheel router disc is bent.
There is a sound. I inquired with customer service, and they proceeded with the replacement. It seems like delivery will take 15 days.
The battery arrived separately from the bike. It seems like the battery took 10 days and the bike took 15 days. The daily riding results are still good so far. I hope to use it for a long time without any major issues.

Its really good .. The technical support was cooperative.. it was easy to install, send all the necessary equipment .. I am a large size, my height is 190 cm.. It did not fit me 100% at first. It might be more comfortable for a smaller person.. But i think with time it will be better because it is very beautiful and very good
