The green Kalkhoff Endeavour 3.B MOVE was snatched from outside its owner’s home on Abercromby Place at around 4:30pm on Thursday.
An iron railing – and the bike’s lock – proved no match for the thief, who swiftly sawed through both while his hapless victim was just feet away indoors.
The bicycle, which comes with an in-built 500 MWH battery, has an estimated value of £3,000.
Its frame contains two unique serial numbers to help identify it: SN 635 660 017 and PN 637 527 034.
The bike’s owner described the thief as a young male who was wearing a grey or black hoodie with jogging bottoms.
After lifting the bike, he is though to have headed off towards Broughton Street.
Those with any information on the location of the bike can contact Police Scotland on 101.
