Bike owners have been urged to be vigilant after the thefts took place between July 13 and last Sunday.
The equipment was stolen from five locations within the East Lothian town.
The bikes were collectively worth more than £4,000.
They include a black framed Voodoo Batu with luminous yellow detail, a sky blue On-One, a grey Trek DS 1 Hybrid and a white framed Fenetic Sprint Electric Bike with black mudguards.
Inspector Andy Hill, from Haddington Police Station, said: “More than half a million bikes are stolen annually across the UK, with around half of these stolen while the bike is on the owner’s property.
“We’re urging people to ensure that bikes are kept somewhere secure and out of sight wherever possible when not in use such as in a storage facility or a locked shed or garage.
“Always secure your bike to an immovable object with at least one good quality lock such as a D-Lock. It’s recommended that you invest at least 10 per cent of the cost of your bike on this.
“If you see any suspicious behaviour, make a note of any person or vehicle descriptions and report this to Police Scotland via 101 – always dial 999 if you see a crime ongoing.”
Insp Hill added: “Anyone who may know the whereabouts of any of the stolen bikes is urged to help us reunite these with their rightful owners and contact either police or the charity Crimestoppers as soon as possible.
“I also want to take this opportunity to remind people to always ensure that, when buying a bike second-hand, the seller can provide proof of ownership.
“If you buy stolen items, either knowingly or otherwise, they can be reclaimed by their original owner, meaning a financial loss for yourself and potentially further police action.”
Those with information can contact Dunbar Police Station via 101 or charity Crimestoppers anonymously on 0800 555 111.
