Two men who posed as Uber Eats delivery cyclists are wanted for stealing bikes from a secure garage in Melbourne.

The thieves, who were carrying insulated UberEats delivery bags, tailgated a vehicle to get past a car park security gate in Docklands about 4.30pm on March 4.

They then used an angle grinder to cut two chained bikes loose on the fourth level before leaving the building with the bicycles in tow.
