We’ve been to the moon and back, can harvest the power of the atomic nucleus, and hope to unlock the secrets of the universe, but surprisingly, there is little we know of how a two-wheeled bike manages to stay in balance. Scratch the last one off the lists, scientists now know the secret to balance. Scientists dabbled in multiple theories, wondering why it was only human intervention that could keep a two wheeler going. Researchers at Cornell University finally created a bike with carefully calibrated mass distribution that can move on happily at speeds of up to 5 mph, finally giving scientists insights into how bikes manage stability and balance. Checkout the videos at Physorg for insights into the study.
