The more advanced option is The EST. After years and years of scientific research, they came up with this innovation. Carefully designed in the laboratories of the tyre manufacturers, they make tyres which take full advantage of the special physical properties of the rubber: it is not elastic in cold. This means the EST tyres automatically increase the rolling resistance and thus force you to cycle slower when it is cold. And the colder it gets the harder cycling gets. A cyclist can have a good work-out while cycling almost at walking speed, with no wind chill effect at all! Awesome!
|The red line is the risk of frostbites without EST. You can see how it rapidly increases. The EST compensates the effects of cold by decreasing the speed (blue line), so the risk stays at the same, low level no matter how cold it gets.|
In fact, the Energy Sucking Tyres are even better than regular brakes. Just try braking on ice. As soon as the wheels lock, you are going to fall. But, don't worry. The Energy Sucking Tyres can function as ABS brakes! They will roll, but slow you down smoothly.
I'm sure whoever came up with this idea will be nominated for a Nobel price. It could be in the phycics category or in the medical category. Maybe even both!
