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.
Also, I was under the impression that this was obvious, but I have been proven very much wrong: IT'S A DOG, NOT A BEAR.
There seem to be a few frequently asked questions, so I will answer them here in hopes that people will read this before asking questions, or misinforming other people with incorrect idea.
1) How do you get off at the top? Very simple: I step off the bicycle, and onto the treehouse. Since this video was made, I have cut a section out of the (temporary) railing to make this easier.
2) What happens if you forget to anchor the bike at the bottom? It would go flying back to the top, but I can't imagine how I could possible forget to do that, because it would be pretty obvious when getting off that something was wrong. But even if I did manage to do that, there will always be a ladder of some sort for backup.
3) What if you fall/is that safe? Of course it's not "safe", but neither is walking across the street. That said, almost every part of the system is many times stronger than necessary, and there is no single part that would make it free fall if it broke. And even if it did fall, I would most likely survive; it's only 28 feet (at most).
4) Can you give us a tour of the tree house? Yes, as soon as it is finished.
5) Can you do a tutorial? I could, but I think that would not be necessary. If you are capable of building this for yourself, you can probably figure out how it works mostly from looking at it. And if you are not that capable, you probably shouldn't be trying to build something like this...

酷發明「自行車動力電梯」！ 登9公尺僅需30秒！
記者曾鈴雅／綜合報導
現代人買房，大多喜歡有電梯的房子，如此便不需辛苦的爬樓梯。但住在9公尺高的森林樹屋上，懶得爬梯子該怎麼辦呢？
美國22歲青年Ethan Schlussler因此自行研發了一部免插電的電梯，只要腳踏自行車升降設備，30秒就可以登上樹屋；既不污染環境，又能擁有都市生活的便利性，懶人出招一舉兩得。

美國愛德荷州的桑德波因特，以自然風光著稱，更因美景如畫、氣候宜人，入選美國西部10大最美的小鎮之一。居住於此的Ethan Schlussler，於是在樹林中搭建了一棟高逹9.15公尺的樹屋，並計畫以此為家。不過每天攀爬梯子上下頗為麻煩，且腳踏車也抬不上樹屋，他於是異想天開，想要為樹屋打造一部不插電的電梯，以省出入家中的時間及氣力。 因為懶得每天爬梯子上下樹屋，激發Ethan Schlussler發明了這部自行車動力電梯。（擷取自Daily Mail）
這部花不到一星期就完成的「自行車動力電梯」，以腳踏車做為電梯骨幹，Ethan Schlussler運用吊鋼絲升降的原理，在樹屋前後裝設滑輪以吊掛腳踏車，另一頭則利用舊熱水器水箱的重量使腳踏車保持平衡，而腳踏車的齒輪運轉則做為升降系統，如此只要像騎腳車自然的踩踏，整個人就像搭電梯一樣緩緩的上升。 結合吊鋼絲升降及齒輪運轉的原理，這部人力電梯能在30秒內登上9公尺高。（擷取自Daily Mail）
雖然為保持腳踏車平衡上升，Ethan Schlussler已刻意降低踩踏的速度，不過經過多次的實驗後，目前這部電梯能以30秒的速度登上9公尺高的樹屋，令人叫好。Ethan Schlussler甚至發現，自身的體重加上重力加速度的效果，下樓的速度還可以比上樓更快。 電梯的方便性，令Ethan Schlussler以樹屋為家的夢想又向前跨一步。（擷取自Daily Mail）
