You may think that complete wheels are necessary when it comes to bicycles. However, one creative (engineer) recent invention shows that two half wheels are just as good as one full wheel.
Sergii Gordieiev is engineer and Internet star. He is (know) for his wonderful inventions. Of these, his latest creation is undoubtedly the most eye-catching. His (usual) bike has two half rear wheels instead of a complete one, and they work together to do the job of a normal one. As strange as it sounds, this crazy bike shows that two half wheels, when used (correct), are just as good as one full wheel. The key this invention is the timing of the split wheels. As one of two half rear wheels is in the air, the other half wheel lands on the ground to keep everything balanced. a clever idea!
Gordieiev says that even if the wheel is perfect, there's really no good reason (break) a perfectly good bicycle. From making the rear frame of the bicycle longer to (cut) a wheel in half and making sure they work together to carry out the function of a full wheel, you can't imagine how much work he has put into the bike. The engineer adds that he hopes to excite people's interest in DIY through (he) example and encourage them to be creative.
