It is too difficult to master how to rock the balance of road cars.

If your average speed and maximum speed are not very high, there is no need to learn to rock the car, especially when locking the car. Once you don't keep your balance, you are in danger of falling off the car. Some people who fall off with X-loaded rocking cars are much more common, and they have seen the pipes on the cars cracked. The purpose of rocking the car is to let you mobilize your whole body and sprint faster when climbing.

If you want to learn, you can start from a gentle slope, the transmission ratio should not be too large, and the pedaling frequency should be lower. Use the flat pedal first, and then your ass will leave the cushion slightly. After this adaptation, try to lock the car on the same slope, and then gradually increase the pedaling frequency and increase the range of body movements.
