Some nice bikes. That Niken was the previous gen (up to 2022). They probably had a black one on display with a TFT which would be the 2023 model. I'm guessing that the Niken doesn't have any updates for 2024.
I left a comment and just noticed yours. I was hoping that the Niken might get an update from the latest 2023 model, but I assume there won't be any updates for 2024. I'd like to see some cool paint schemes for the Niken.
