Yes, "OP" means original poster
30 kg is a lot of weight to get up hills. I weigh the same as you, and with a 16kg load, I often use my lowest gear on steep or long sustained grades. Some of our mountain passes here require climbing for 65 km; nothing really steep, mostly average <6%, but with steeper pitches.
Rowen,
90 rpm is my normal cadence. I just shift down to lower the cadence if needed. I can easily handle my loaded bike at 3.5 mph with very little wobble, but the hill has to be steep enough to give me substantial pedal resistance. It still beats pushing a bike up a hill.
