A quick search of the Gazette shows that the council moved it:

"2) The general effect of the Orders would be to introduce new bike hangars on the following roads: ... d) to remove the bike hangars at the following locations and replace with resident permit parking spaces: ... ii) 1 bike hangar on Mackenzie Road, outside No. 50 Mackenzie Road. "
Someone probably complained that their parking space was removed.
