How to protect SLR cameras during riding?

Buy a saddle bag that can hold a SLR. Spend less than 100 yuan on Taobao. It leans back with one shoulder. Now tie the bag around your waist with a belt or other belts, so that it won't swing violently when riding and won't damage the camera. Don't put the camera in the handlebar bag. First, it increases the inconvenience of turning operation. Second, it is easy to bump the machine. Third, once you fall, it is easy to break the camera. You can also put it in your backpack with some shockproof foam. This is my experience.
