Three late withdrawals left City sending out a patched-up side which - in the end - could not cope with an Aber side in a good run of form. Rae Ingram, Clayton Blackmore and Ricky Evans all cried off during the afternoon which meant Huw Griffiths started for the first time this season and Gareth Williams slotted into midfield.
City fell behind on 17 minutes when Phil Priestley saved from a corner, but Lee Spike headed home from close range. Left winger John Lawless, who had impressed with Burscough last season, was causing Peter Hoy trouble on the City right and it was no surprise when he was yellow carded for a foul on the flying winger.
One Citizen worthy of special mention was Huw Griffiths who battled gamely despite his lack of fitness, working hard to quell the threat of Lee Spike and co.
Despite falling a goal behind, Bangor played well and had a good share of possession without managing to beat home custodian Worsnop. However this revival took a body blow when Peter Hoy was yellow carded for a second time for a foul on Lawless and sent to the dressing room.
Soon after the interval Bangor were back on level terms when on 48 minutes Gareth Williams crossed from the right for winger Kenny Burgess to fire home from in front of goal.
The scores stayed level from much of the second period, but as Bangor tired Phil Baker fired a freekick from his own half over Phil Priestley and into the Bangor net. City claimed the award was indirect but the goal, timed at 75 minutes, stood regardless.
On 85 minutes Lee Spike made it 3-1 before City replaced goalscorer Kenny Burgess with Ross Jefferies. A second strike inside a minute made it 4-1 on 86 minutes when John Lawless scored from another freekick as the ten men finally wilted in the closing stages.
