I purchased two Como 2.0 ebikes last August. Recently I discovered the sticker on the underside of the frame that says my bike was manufactured in December 2017 and my wife's bike says it was manufactured in June 2018. Both bikes were sold as 2019 models. Is this "normal" I am not aware of any other products with an advertised model year that far removed from when it was manufactured. One concern I have is that the batteries were already over 18 months old when we got the bikes and may not last as long as they might otherwise. Thank you.
