In today’s data-driven cycling world, power meters have become a must-have for riders who want to measure, analyse, and improve performance. Unlike speed or heart rate, which are influenced by external conditions, a power meter gives you objective, consistent feedback on your actual effort—making it the most effective tool for training and progression.
At BikeHeaven, we’re here to demystify power meters and help you decide which type is right for your riding style and goals.
What Is a Power Meter?
A power meter is a device that measures the power output of a cyclist, typically in watts. Power is a direct measurement of how hard you're working, which makes it far more reliable than heart rate or perceived exertion.
By training and racing with power, cyclists can:
-
Train in targeted power zones
-
Track performance gains over time
-
Pace efforts with greater precision
-
Make the most of limited riding time
Whether you're chasing a personal best, improving endurance, or building speed, a power meter provides the data you need to ride smarter.
Types of Power Meters
There are several types of power meters, each designed to measure force from a specific point on the bike. The best option for you depends on how and where you ride, and whether you want to move your meter between bikes.
1. Pedal-Based Power Meters
Pedal power meters measure force directly at the pedal. These are easy to install and remove, making them ideal for riders who use multiple bikes. Many models offer dual-sided readings, providing independent data for each leg.
Best for: Road cyclists, triathletes, and those wanting easy transfer between bikes.
2. Crank Arm Power Meters
These measure force from one or both crank arms and are often among the most affordable entry points into power-based training. Installation can vary depending on crank compatibility.
Best for: Road, gravel, or MTB riders looking for a cost-effective solution.
3. Spider-Based Power Meters
Mounted at the centre of the crankset, spider-based power meters measure force from both legs and are known for consistent and balanced readings. They’re highly accurate and commonly used by performance-focused cyclists.
Best for: Riders looking for a blend of precision, durability, and integration.
4. Crankset-Based Power Meters
These come as a full crankset with the power meter integrated. They offer some of the most accurate data available but can be more expensive and may require compatibility with your drivetrain.
Best for: Competitive cyclists and serious enthusiasts wanting high-quality data.
5. Hub-Based Power Meters
Once common, hub-based meters are now less popular due to limited compatibility and flexibility. They measure power from the rear hub and offer good consistency but are harder to transfer between wheels or bikes.
Best for: Riders who don’t need to swap wheels and prioritise durability.
Choosing the Right Power Meter for You
When deciding which type of power meter to go with, consider the following:
-
Bike compatibility – Ensure the meter fits your crank, pedals, or drivetrain.
-
Ease of installation – Some are plug-and-play, others require more technical knowledge.
-
Budget – Options range from accessible single-leg meters to high-end dual-leg systems.
-
Training goals – More advanced metrics (like left/right balance) may matter if you're racing or analysing in detail.
-
Bike usage – If you switch between bikes often, a transferable solution like pedal-based may be ideal.
Power Meter FAQs
Do I need a dual-sided power meter?
Not necessarily. Single-sided meters are great for most riders, while dual-sided meters offer more detailed insights, especially for those recovering from injury or focused on pedalling balance.
Are power meters hard to install?
Some types (especially pedal-based) are very easy to install. Others may require specific tools or bike shop assistance.
Can I use a power meter indoors and outdoors?
Yes. Many power meters pair with indoor trainers, head units, and training apps like Zwift and TrainerRoad for year-round use.
