Why climb 30 feet up when you can bike? Check out Ethan Schlussler’s Bicycle Powered Tree House Elevator:
“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,” he writes.
“It was originally a 20-something speed bicycle, but first gear wasn’t slow enough, so I cut the large sprocket off the front, and welded it on the rear to get a lower gear. I also had to do away with the de-railers and make a new chain tensioner.”
The treehouse is not yet complete, but Ethan says, “I will be building walls and insulating it in the next few weeks, and eventually I intend to live (or at least sleep) in it. “
