Bicycle-Powered Treehouse Elevator

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.

Pedal Power: The Quest for the 100 MPH Bicycle

Pedal Power: The Quest for the 100 MPH Bicycle

England’s Tom Donhou makes some beautiful hand-built road and mountain bike frames. He got the idea to put his handiwork into action build (and pilot) a bike that could reach 100 miles per hour on the flats. Working in his shop and with England’s Royce he build a rocket of a bike with a monster front chain ring nearly as big as his wheels. !He was inspired by the homebuilt cars roaring across the salt flats of Utah. There are no salt flats in the U.K. so he choose a two-mile WWII-era runway. But his quest didn’t stop there. The short documentary below documents his efforts and those of his collaborators. It’s a great story of ingenuity, daring, and the maker spirit.
