Types of Cycling Power Meters & Buying Guide

Over the years several manufacturers have produced numerous type of power meters that can be used on different road bike locations. Here are several categories of power meters depending on the places to be installed:

  1. Pedal power meters –placed in the pedals
  2. Hub power meters –placed in the rear hub
  3. Crank power meters –placed on the on crank arms
  4. Bottom bracket & Chain ring power meter –a bit difficult to mount
  5. Spindle power meter –place in the in the spindle of a chain set

The different power meter locations have specific advantages and disadvantages hub based systems. These are amongst the most simple power meters on the market because there are far fewer different forces acting on the strain gauges which means that they can be very accurate and reliable a lot of engineer’s regard hub based systems like this to be amongst the most accurate power meters on the market.

On the other hand you can expect your power readout to be slightly lower than if you’re measuring at the crank or the pedal because you’re actually accounting for drivetrain losses through the chain the other key thing that you need to be aware of with a hub based system is that you won’t get any differentiation between right and left pedal.

Pedal based systems are really easy to fit and swap between bikes but they can be slightly less accurate because of the complexity of the force measurement being measured at the pedal and also being exposed on the side of the bike that can also be at greater risk of damage

Single sided crank arm systems can also be relatively easy and quick to swap between bikes but it does mean that you need to have the same sort of chain set on both your bikes and not everyone always does

Bottom bracket and chain ring based systems can be very accurate and also offer very low maintenance however they are arguably harder to fit and this is something that’s made even more difficult by the seemingly endless number of bottom bracket standards on the market today

finally you should also consider the warranty of the power meter that you want to buy because in our experience they’re quite complicated bits of electronics they can go wrong and they can wear out so if something does go wrong you want to make sure you’re covered.

Almost all spin bikes allow you to install out your current pedals for new ones, making it simple to attach a set of power pedal. Please keep in mind that these spin bike pedals power meter need road cycling shoes. 

A power meter pedals attaches to the pedal of your bike and measures the amount of power you generate when cycling, whether it’s on an indoor cycling bike, or outside on a road or mountain bike.

Power meter pedals are ideal for someone who wants to get something out of their cycling performance or who wants to link to apps like Zwift to see their cadence, speed, watts, and distance traveled in real time.

Crank Power Meter for Spin Bike

If you’re looking for a crank-based power meter for spin bike we would not encourage you. These crank-based power meters require specific cranksets these are a hassle to install the power meter crank arm on spin bike. Crank-based power meter, such as those made by Stages, 4iiii (crank-based 4iii precision power meter), and Pioneer, replace your non-drive crank arm and calculate the power provided by your left leg. These are also the cheapest cycling power meter.

These crank-based power meters take about ten minutes to install. Although the only drawback with the crank-based power meter is that you have to confirm that the cranksets are compatible.

You can also use a crank-based power meter but just make sure the dimensions is right and fits well onto the bike’s crank arm. Crank-based power meters like those from Stages use small pods packed with electronics. You can go DIY and bond the crank-based power meter to the back of one of the exercise bike’s crank arms.

At the time of writing this article no manufacturer produces power meter crank for spin bike. Power meter pedals are by far the fastest and most straightforward method of adding power meter to spin bike and some of the best type of power meter for spin bike.

3. Garmin Vector 3 Pedal-Based Power Meter

The Garmin Vector 3 is a pedal-based spinning bike watt meter with a lot of features. The Version 3 has a dual-sided power reading measure, unlike the Vector 3S model. As a result, instead of just the left leg, you get balance input on both sides.

The Garmin Vector 3 seems to address the drawbacks of the previous model. Unlike its predecessor, the Vector 2, the V3 power meter is entirely enclosed inside a stylish pedal – this configuration avoids the unpopular practice of dangling an unprotected strain gauge off the pedal.

It also eliminates the need to set the pedals with the correct level of torque.

Garmin advertised their pedals as weighing 316 grams, but we found that they weigh 324 grams. The pedals themselves, which were initially manufactured by Exustar, a third-party brand, have now become a Garmin in-house venture.

They use needle bearings instead of the bronze pedals which can comfortably accommodate a heavier rider weighing up to 100 kilograms.

They are compatible with both Bluetooth and Ant+, allowing them to work with a wider range of software.   The Garmin Vector 3 uses LR44 batteries, which have more reliable performance over 120 hours of riding. Both of the power pedals does have its own battery compartment.

Customer review
“These are excellent power meter pedals that are simple to install and configure. You can set your Garmin power pedals to automatically trigger a calibration any time you use them, which is sure when swapping between bikes with different crank lengths or simply to make your readings are accurate. The 3S only has a left pedal power meter, but it operates flawlessly and has accurate power readings. These are one of the best power meters I have.”

  • Compatible with zwift 

  • Smooth Silent Spinning

  • Built To Last

  • Lightning-fast Setup

  • Magnetic Flywheel

  • Noise Reduction 

  • 6 Resistance Settings

There are several bike trainers available. They usually start at about $250 and go up from there, but you can get them for less if you look around. In addition to having a great road feel, they’re also extremely compact. The Saris Fluid 2 is another great trainer.  In reality, it’s one of the best-selling trainers ever and features a big, accurate flywheel that gives a road-like time.

If you go this way, there is one thing to keep in mind. Many popular indoor training apps will directly transmit gradient changes to the trainer, and provide a more actual training experience. However, they will only do so if you have a ‘smart trainer’.  But, if you choose a dumb trainer like the ones mentioned above, be aware that your trainer would not be able to provide this input. As a result, certain people, whether or not they have a power meter on their bike, would use a smart trainer like the Garmin TacX Neo 2T Smart Trainer.

Option 4 – No Power Meter on Your Bike – Then Buy a Smart Trainer

If you do not have a power meter on your road bike at present and you want to drive indoors, you may need a smart trainer. These sophisticated but expensive trainers take the indoor cycling with power meter to next level. They have an integrated power meter. The power meter transmits cadence and power data to your bike console, or training app.

Best Smart Trainers for Indoor Cycling

  • Foldable: yes

  • ANT+ & Bluetooth

  • Includes front wheel block

  •  +/- 2% power accuracy

  • Dual ant+ fee-c and Bluetooth 

  • Zwift Certified

  • +/- 5% accurate power readings

  • Dual ANT+ FE-C and Bluetooth

  • Cadence, speed data

Moreover, as the trainer determines power at the rear wheel, they measure power from both legs. 

When used in conjunction with a training app, these trainers can send suggestions right to the pedals. The trainer basically takes care of the resistance.

This further simplifies professional training. Once interval training is scheduled in your training app, the intelligent trainer will change the wattage from one interval to the next to precisely match your training. What you have to do is spin the pedals.

Smart trainers start at around $400, but most popular versions sell at or above $700. Saris H3 Smart Trainer or the Saris M2 Smart Indoor Electromagnetic Resistance Bike Trainer are among the popular trainers. 

The Garmin TacX Neo 2T Smart Trainer is also a popular model. The NEO 2T features adaptive inertia technology that accounts for rider weight as well as other variables to provide a fair and seamless ride. It can also withstand sprints of up to 2,200 watts, simulate incline up to 25% and measure the power data in 1.0% error range.

These smart trainers are nice, but you can’t ride outside in them. So the disadvantage to this option is that you would not be able to use a power meter on your bike for outdoor training trips.

Spin Bike Power Meter & Zwift

When some questions, can I use Zwift with just a power meter? Does a power meter provide a decent Zwift experience on spin bikes?

The metrics would be close to accurate. To replicate hills in Zwift, however, you must manually alter the resistance, while a smart bikes or smart trainers can set the resistance automatically for you.

Another piece of advice is heard is “grab a cadence and speed sensor and you’re free to go.” The well-intended recommendation makes use of Zwift’s option of combining a speed and cadence sensor with a dumb trainer. Zwift has essentially checked some dumb classic trainers, and other supported trainers and basically, you’re calculating Z watts for Z speed.

They have a different looking table, but possibly are based on estimates that may or may not be accurate, for unlisted trainers. A spin bike will be more accurate in Zwift with a power meter or an indoor bike with power meter like the Stages SC3.

Stages SC3 spin bike with a built-in crank power meter is compatible with Zwift. Although it does not immediately change resistance, we believe it still offers a strong Zwift experience.

It isn’t the best experience because there is no freewheeling because you have to adjust the resistance manually, but it is a better experience than a dumb trainer because the spin bike is nearly quiet and has no maintenance. Simply get on and ride and if you don’t like to by here is video.
