i am very satisfied with the bike. the feeling of riding with motor assistance is very natural. the quality of workmanship is very high. And the bike looks very good. i was annoyed about one thing: i adjusted the saddle higher, right after unpacking. in the process, the black paint on the seat post was scratched off, even though i had turned the screws all the way up and was very careful. that is very annoying and looks ugly. Maybe a little grease would have helped?
