Cycling 10 km every morning and evening, can you lose weight?
There will definitely be some effects, but if you ride a bike at 10 km, the amount of exercise is still relatively small.
If you want to lose weight, you must first understand your physique and why you are obese. Secondly, we should take a multi-pronged approach, not only exercise, but also diet, exercise and work and rest. Finally, I wish you success.
