If it's the orange Giant in the photo up thread, they are 25kg/55lb. I guess it could be lowered to someone receiving it, but it seems there was only one person seen on CCTV leaving. A second person may have not left the area/ not left at the same time? If the bike was dropped, someone would hear that. They seemed to have a lot of bikes, perhaps there is a bike storage garage near the apartment block?
