WOW! I just looked at my 5 year old Schwin bike which is in the shed and I haven't ridden for 3 years. It has 36 spokes on the wheels. The bike is really heavy (I think it's steel) and has fat wheels, but I could use it for transporting heavy things. The bike is so heavy I can't lift it up to get it on the bike rack on the car. The weight probably isn't an issue though because I would be leaving from my house. I'd still rather use my Giant because it is so much lighter and easier to ride. The Schwinn is so heavy it takes a lot of energy to ride, but I probably could use the exercise.
