If you postpone something it normally means to delay to a later date, but if canceled it means its over. I think 2021 would be over and not postponed? Are they planning on doing it later this year, probably not. So I would say cancel it for 2021 and say that….. would almost be impossible to do it later in the year, would be like starting from scratch with 1500 bikes………
