Simon and Lisa have a full list of their kit posted on their site with lots of good tips they've learned along the way.
I think they've done a great job with the bush-camping considering that they were not wilderness survival enthusiasts when they started. They certainly are now.
To carry all of this on a bike was an amazing feat of organization and redundancy. As they said "This is our life". Lisa cooks a wide variety of meals on her one burner stove. You can't live on Ramen noodles for two years straight. Mac
