Twicycle: The Hand-cranked Bicycle
For centuries, bicycles have been powered only by leg movement. While there have been many variations of the bicycle, all of them are powered using leg muscles. We've heard of the tricycle and the unicycle, but now a new bike is going to be hitting the streets soon, the Twicycle. Although the name sounds humorous (sort of like Tweety bird trying to say "tricycle"), the bike literally uses twice the amount of movement. The Twicycle can be powered by leg movement and arm movement. These two forms of cranking allow the bike to go up inclines easier and reach faster speeds. Check out this bizarre bike in action below!
