I really love my bike. And I ride it every day. This is why I frequently pass by this amazing machine of incredible value. It is a bicycle tube vendor that serves and helps bugged bikers whose bike tire has fallen flat. Every day of the week at all times. With a good brand for tubes.
So all you need to do if you have a flat tire: go there with some coins and buy the repair tube. They have 26″ and 28” tubes with various valves, so most common inconveniences can be handled. If you have two left hands you can check out the store and get help or even rent a bike here. But my personal focus is the yellow vendor. I simply love the idea of having a bike tube at my 24/7 convenience. By the way: if you need a tube you have to push hard on the button after paying in coins. This is what is said in German at the button section.
