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

Reinvent the bicycle – based on idiom Reinventing the wheel for best desciption of innovations for bicycle
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.

Road bike aerodynamics improvement
The appearance of the bicycle has not changed for 100 years. Unlike airplanes, cars, motorcycles. Maybe it’s no need road bike aerodynamics improvement? Continue reading Road bike aerodynamics improvement
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
Calculation of necessary power on wheel depend on given speed
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
Reinvent the bicycle. Introduction to section
Looks like development of the bicycle as a vehicle is quite delayed in comparison to cars, motorcycles, even scooters. Continue reading Reinvent the bicycle. Introduction to section
