I bought a 2022 Gen 3 Levo several weeks ago. The motor had a loud buzzing sound, so I had the bike shop order a replacement motor. The original motor had a build date of Dec 3, 2021. After the replacement motor was installed, I noticed the build date was Nov 29, 2020--older than the original motor. Just curious if anyone else has had replacement motors that were 2 - 3 years old and if it's anything I should be concerned about.
