Losing 30 kg solely through cycling is not realistic in a short period of time. While cycling is a great form of exercise that can help with weight loss, it is important to also focus on a balanced diet and other forms of exercise to achieve such a significant weight loss goal. It is more realistic to set a goal of losing 30 kg over a longer period of time, with a combination of regular cycling, a healthy diet, and potentially other forms of exercise. It is important to consult with a healthcare professional before starting any weight loss journey to ensure it is done in a safe and sustainable manner. **

Full-face helmets provide more protection for the face and jaw in the event of a crash, making them better for more aggressive and high-speed cycling such as downhill mountain biking or BMX racing. However, for general cycling, half-shell helmets are often preferred due to their lighter weight, better ventilation, and less restrictive feel. The choice between the two depends on the type of cycling and the level of risk involved. **
