The large-capacity saddle bag can put all products in it and has extra space. Although it can hold a lot of things, we recommend not to store heavy objects, because during riding, the overloaded weight will greatly reduce the service life of the saddle bag. After binding the saddle bag to the bicycle, check whether the binding is tight, because too loose will cause the saddle bag fixing strap to be damaged as the bicycle jumps during driving.
