The market for power meters has become increasingly competitive, offering a wide variety of models that can be placed in various parts of the bicycle. Each meter has its advantages and disadvantages based on its location, accuracy, and price.

Rear Wheel

Hub-based systems such as the Power Tap G3 are simple power meters that operate with less detailed data on the meter. The hub is considered an accurate location for measuring power by many engineers.

Bottom Bracket

This type of power meter measures the excess force within the transmission cycle, resulting in a slightly lower power measurement compared to pedal-based power meters. Dirty drive chains may also affect accuracy.


Chainring power meters provide the most accurate power measurements, but they lack the ability to swap between bikes like pedal-based systems. They also do not accurately measure left/right power. However, these issues can be mitigated with a bottom bracket sensor and compatibility when switching bikes.

Crank Arms

Crank-based systems like the Garmin Vector allow for easy switching between bikes and generate individual records for each bike.


Pedal-based power meters can be easily adjusted and swapped between bikes, but the complexity in measuring force can affect accuracy. They are also more susceptible to damage when exposed, which may shorten their useful life.

The concept of power can be explained by the study of physics. When an object (mass) is displaced, it creates a force that moves a distance in a given time. The resulting power is calculated by electronic circuits that convert this energy into watts, providing data in the power meter. In simple terms, the mass is the rider plus the bike, and the distance is the road traveled.

However, the resistance to movement is not consistent, making it more complicated. The equation for power is Force x Speed = Power, which is applied to a specific part of the bicycle such as the axle, crank or pedal.

Manufacturers face challenges in accurately measuring this force, as small details can affect the results. The location of the meter, the quality of technology, and even the resistance to temperature can impact the measurements. Therefore, it is important to consider these factors when choosing a power meter for cycling.


Single-sided power meters are a type of device that measures the power output of only one leg, typically the left one, and then estimates the total power by doubling the reading. However, this method of doubling the power output of a single leg may not always provide a completely accurate representation of your actual power output.

It is important to note that imbalances in power output between the left and right legs are common, with a difference of around 48/52%. Therefore, before investing in a single-sided power meter due to its lower price point, it is recommended to check for significant imbalances in your power output.


These devices calculate power output by combining the power from both legs instead of measuring each leg independently. While accurate, they don’t provide separate measurements for each leg. A popular example of this type of power meter is the PowerTap.

The latest trend in power meters is wireless connectivity with smartphones, allowing data to be recorded through an app. New models are equipped with smart Bluetooth connectivity, enabling easy connection with phones or firmware updates.

In addition, some power meters can transmit via ANT+, allowing connection with popular cycle computer systems, such as Garmin. If you’re interested in learning more, check out our article on the best cycling computers currently available on the market.


Accurately measuring power data can provide specific performance requirements for a particular discipline or competition. It allows for more objective training that fits an individual’s needs.

As a cyclist, monitoring speed during each ride can be beneficial. While heart rate monitors provide some information, knowing one’s power output offers a quantitative and repeatable way to evaluate training effectiveness.

For instance, if it takes longer to finish a training route but power numbers are up and heart rate is stable, it indicates that the training is working. On the other hand, power data can also indicate when it’s time to rest. An abnormally high heart rate or reaching a particular power level might suggest it’s time to cut the ride short and head home.
