12 kg (~26.5 lbs) is pretty heavy for a road bike. The UCI limit is 15 lbs but no normal person will have a bike that light so let's say 16 lbs. If my math is right, that weight difference works out to an extra 16 W you have to produce to do that same climb in that same time, which is significant, roughly 6% of your power.
5+ W/kg for 45 minutes is very good though!
In his video, he's 53.7, and holding bike, 65.1, so that's 11.4kg/25lbs with a big under saddlebag and a really big water bottle (full or not?). Probably 21-22lb bare, which is typical for a not super expensive, mid-range road bike. Free gain would be to ditch the bag for the effort, and carry only as much water as needed. Next some low rolling resistance tires.
