Bicycle-Powered Treehouse Elevator
Ethan Schlussler of Sandpoint, Idaho, built this clever bicycle-powered treehouse elevator to make it easier to reach his nearly 30-foot-high treehouse. “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,” he writes.
