In situations like these, there is only a problem if there’s a problem. I would suggest the EC allows he bike to be moved across common property and on to th terrace provided there are no issues with, safety, damage to common property, noise and smell.
If the bike turned out to be a de-muffled Harley-Davidson and you were woken every morning and night by its roar and rumble, tyre tracks appeared on your laws and the stench of petrol fumes invaded your homes, it would be nice to be able to reverse the decision without too much hassle.
