How do bicycles stay upright and the story of learning to ride a backwards bike


Angular momentum and gyroscopic precession are critical to keeping a bicycle balanced.  To see why this is the case, see what happens if the brakes lock the wheels in place while the bicycle continues to move forward by skidding along the road.

It sounds like the problem was redefined in such a way as to eliminate the 'conservation of angular momentum' as being a significant contributor by someone who invented a very awkward bike that remains stable without angular momentum. If you are talking about a normal bike that people actually ride, then it is you who is redefining the problem. Perhaps normal bikes do rely heavily upon conservation of angular momentum in order to remain stable. The fact that another bicycle was created that does not rely on this effect says nothing to those bikes which do. In other words, it is a false equivalence. The term bicycle is much too vague, as multiple types can be constructed that rely on different factors in order to achieve stability. Just because one type of bicycle eliminates the need for one factor does not make that factor irrelevant for other types of bicycles.




The backwardsbraincycle. Interesting. Riding a reversed steering bicycle is impossibly hard before our brains adjust (which takes a load of practice). Destin shows that a kids brain had much more plasticity (his kid took 95% less time for his brain to "click"). He also noted something important: that he had the knowledge of riding the bike but not the understanding. So information=/=knowledge=/=understanding.


How to learn to ride a bike in 5 simple steps ?







Learning how to ride a bicycle doesn't have to be difficult or painful. With the proper size bike frame, a helmet and a few minutes of practice just about anyone can get it. To begin, lower the saddle so you can sit on the bike with both feet reaching the ground for stability. Next, kick along with both of your feet and get used to balancing. Once you're comfortable coasting for short distances try putting one foot on the pedal while kicking with the other. Make sure you know how to use the brakes (some bicycle pedal backwards for braking and others have hand brakes). The final step is kicking off and putting both feet on the pedals. At this point you should be able to pedal the bike and stay balanced but if you feel like falling you can just put a foot down to catch yourself. enjoy riding your bike for exercise, affordable transportation and to meet new people in the community.
