BD bikes come with low end kenda tires. It's a good idea to get tires with better puncture protection,like the panaracer ribmo or t-serv protex.The hole in your tube is not caused by being bad(unless it's a long tear along a seam) but more likely by some debris(glass,thorn etc) making it's way through the tire.Before installing a new tube, line up the old tube with the tire and check the tires inside around the puncture area for anything poking through.
