Sir Chris Hoy's Hidden Golden Bikes

City council? Get to the council building, wouldn't be surprised if they had a hand in this being that they fund the national cycling centre.

Could also be cricket club? Get down Old Trafford.

Unlikely to be cycling club.

Aye, there is no 'manchester cycling club'. So City Council, possibly town hall is a good shout.

No 2nd or 3rd clue yet though. And the 3rd has the code.
