Ideal bike computer and estimated power

Bike computer collects data from sensors, then makes arithmetic operations and shows the result: speed, cadence, heart rate, travel time, etc. Sometimes – power, but it is usually a separate device. Frankly, it’s nonsense, when such a simple device is called as computer. It is rather a calculator, which is not much different from the first mechanical meters of wheel revolutions. But what it would be if real computer, for example, such as in smartphones, work “on board” during cycling? Continue reading Ideal bike computer and estimated power

Mechanical doping and average speed

Mechanical doping or technological doping  or tehno-doping this is related to devices for improve athletic performance. In cycling problem has become so serious that before each race bike scanned, judges search for hidden electric motor. I hope that in this case the developments of mechanical doping may well be used officially, if replace the battery by capasitor. This can give the with skillful management a significant increase of average speed.

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
