Confused..... that always used to be the bike parking, it had marked bays as such. Google streetview agrees with me. Satelite (newer image) shows different though but I can't spot any bike parking. Not been there for a while.

Guess that's West Bay plonked on the list of "Goodbye, I'll spend my money elsewhere", as they seemingly want to add complication to my life.

the surface there isn’t designed for the weight of a motorcycle stand
Well if it's not up to that then I'd opine a family of 4 obese hippo-croca-pigs sat on one of those benches shovelling fried crap down their throats are probably putting as much pressure through each bench leg as a motorbike on a sidestand, so they better ban fat people from the benches.
