If he just built the treehouse on the ground he would have saved himself a lot of trouble. But he didn't so there now. I can't wait to get invited over to this guys house! Lets so the math: a rickety 30 year old bike, thin ropes, towering heights, and a boulder to fall on and no one even got hurt. This bike elevator clearly relies heavily on witchcraft. Burn it now with fire!!!
I have built a tree house (though it is not finished yet) that is nearly 30 feet up a tree. I got tired of climbing a ladder six and a half million times a day, so I made a bicycle powered elevator to solve this problem. Don't you wish you had one? :p I welcome any questions or comments.
