Two late goals finally clinched victory for the leaders over a Trearddur Bay side which gave them a much tougher test than most have managed this season.
Bangor led 1-0 at half time courtesy of the 19th minute Ceri Lois goal.
Trearddur defended determinedly until 1876 eventually doubled their tally in the 75th minute, Stevie Donougher converting from a Mia Roberts assist.
Four minutes later, Cerys Parry added a third for the table-toppers.
Full credit to Trearddur Bay, though, for putting in a tremendous effort.
This Bangor side have been hammering teams all season, but they did not have it all their own way against the ladies from Anglesey.
Reflecting after the match, Bangor 1876 manager Aron Griffith said: “Brilliant way to kick-start the second half of the season. A bit rusty at times but got the goals in the end. Taking nothing away from Trearddur Bay, they battled and played some brilliant football. Onto our next match now and hopefully we keep the winning streak.”

Playing their first match since November 13 – nine weeks ago – Pwllheli looked refreshingly sharp as they sealed the win which moved them up to fourth place.
The deadlock was broken on the half-hour when Marsli Owen finished following a cross into the box.
Charley Davies doubled the lead before half time when she tapped in from a corner.
Bess Roberts came on for Owen in the second half and made quite an impact.
In the 70th minute, Roberts made it 3-0 with a stunning header into the top corner.
And Roberts struck again on 88 with a firm shot inside the box.
Top-scorer Lois Thomas rounded things off with a beautiful top right-hand finish from the left side of the box.
Llanfairfechan, who are enjoying a very impressive first season in the league, were well beaten on the day but are settling in some new signings.
