Power meter

Cycling Power Meter

Cycling power is an indicator to tell how much energy from your feet to make the bicycle moves. By sensing the cadence of pedaling and force on the crank or pedal, WUSA develops the algorithm to tell the output power on your riding.

Collecting data on cycling computer and smartphone

Why cycling data ?

You may ask why counting spinning data is important? Higher cadence using small gear makes your muscle burns fats which means more higher aerobic performance. On the other hand, lower cadence with high gear makes your muscle burns glycogen which means you will get fatigue more quickly. Then what is the best RPM goal for a beginner cyclist to reach? You can find out your best RPM by using Spindo and you will have to maintain a steady cadence to get your current best RPM. But if you want to increase your RPM, there is no shortcut to improve your RPM from 30 to 90. By calculating the output power, you can use these data and train yourself to sustain on a steady cadence with a lower output power, so that you can know if you are pedaling right.  

The more accurate spinning cycle you get, the more correct RPM will be calculated.  Spindo is strong in sensing technology to handle this precisely.  Utilizing the data which Spindo tells, you may  trace your cycling record  and see if you have improvement. 


Pedaling right and get improved.


Not only an exercise, and have fun.
