How speed depends on tires quality

Choosing of tires is paid of much attention. At the same time it often said (especially for road bikes), that 80% of the efforts goes to the air resistance. How significant then the dependence of the quality of tires?  Continue reading How speed depends on tires quality

Headwind and average speed

Headwind can greatly reduce the speed of bicycle while tailwind sometimes not so noticeable. But the average rate of “back and forth” is still falling. How much it because of wind?  Continue reading Headwind and average speed

Why hills lower average speed

The average speed is quite whimsical. It is easy to lower, but it is difficult to increase. If the way goes through the hill, it always “bites” from the average speed, in addition to being exhausting.  Continue reading Why hills lower average speed

Finding cycling perfomance parameters using another’s power meter

There is quite many experimental data from the happy owners of power meters. Such data could be used for finding cycling perfomance parameters as roller resistance and air drag.  Continue reading Finding cycling perfomance parameters using another’s power meter

How cycling power spent during moving a bike

Bicycle speed depends on the power of pedaling, on type and class bicycle, on road condition and on wind and elevation. It is interesting to evaluate in what proportions.  Continue reading How cycling power spent during moving a bike
