A Bike Water Bottles is an essential accessory for the experienced biker and beginner, which is essential when traveling long distances, on hikes. For convenience, it is securely fixed in a special holder (made of aluminum, carbon fiber, or thermoplastic), which prevents it from falling out. At the same time, they are easily attached to the frame, do not weigh it down at all, and, most importantly, do not scratch it. A bicycle flask requires some care in order to protect yourself from the ingress of pathogenic microbes. To do this, warm water with any liquid dish detergent will do. You can't just wash it with boiling water - the plastic can be deformed, you will have to buy a new one. The cap should also be cleaned periodically because blockages (sand, dust) lead to seizures.
