There are a great many methods of how to learn to ride a bicycle. And they are all correct, you just need to find the only approach that is right for yourself and start training. However, if you are teaching your still far from adult child, then you need to be extremely careful in order to avoid unnecessary injuries (injuries in general can be avoided, alas, in no way).
So, if you are explaining to your child how to ride a bicycle, it is best to choose a tricycle. Let him become his first transport. You don’t really need to think about how to learn to ride a bicycle of this type, since it is quite easy. In addition, there is a lower risk of falling, but the child will already understand the driving technology. After he mastered it, you can transfer it to a two-wheeled bicycle with side wheels, which can be removed at any time. They do not provide the same reliable support as it was with the previous vehicle, and thanks to this, he will receive the first skills of maintaining balance. This is one of the most important moments of science called "how to learn to ride a bicycle." Then the wheels can be removed and the bike slightly held during the first "adult" trips of the child. Do not worry too much about falls and bruises. In the end, we all learn to ride the bike the same way, paying off with bruises and abrasions. However, after such a long journey, as described above, all possible injuries are minimized.
With the children sorted out. Next in line are adults. How to learn to ride a bicycle for an adult? In childhood, this seems easier, and courage in children, as it seems, is gaining more than in adults. So, if you decide to start training, you will need to start the bike itself. If you don’t have one, you can borrow from someone you know. It is best to find a bike with a low frame - for greater convenience and to reduce the risk of injury. Further, for better protection, it would not hurt you to get elbow pads, knee pads, a helmet and other similar paraphernalia (but this is only according to your desire). Learning to ride best on an earthen surface so that falling is not so painful and dangerous. If there is nothing like an earthen pavement suitable for riding nearby, then it is better to train on flat and smooth asphalt, without pits and potholes. For training, it’s better to choose a simple bike, but if it still has several gears, it’s better to put it on the middle one - there will be more effect.
Learning to ride is better not alone, but with a friend. When you start riding, let him hold the bike by the saddle or even slightly push. Do not drive slowly, but at an
average speed so that your assistant does not run too fast after you. When you accelerate enough, your comrade must let you go - and voila! You go! Spin the pedals smoothly and balance the movements of the body. At the end of the path, do not jump off the bike, much less fall. Slow down the speed gradually, and just before the moment you stop, rest your foot on the ground. After a week of training, you will already be able to perfectly master the skill of
cycling. Although, maybe so much time will not be needed. For some, one day is enough for some.
