Utterly sick of it. It has worsened dramatically since apps such as Deliveroo. I ride a motorcycle myself. Much of the noise nuisance is due to rider technique combined w illegal bike status. There is a law re noise levels. As another post has said the problem is that there is no enforcement. Hopefully electric bikes and mopeds will change bike roadworthy status. I contacted Wandsworth council once, motivated by Westminster banning moped deliveries. Wandsworth not at all interested and couldn’t see the issue. Perhaps they will in future??
