Adding a power sensor to your bike: what options are available depending on your budget?

Whether you're a recreational cyclist looking to better understand your performance or a dedicated athlete aiming to structure your training, adding a power meter is one of the best investments you can make for efficient progress.

Good news: there are now options for every budget. Here's an overview of the main solutions available.

Option 1: Add a Power Meter to Your Existing Crank Arm or Replace It

This option involves installing a power meter—such as the 4iiii model—on the left crank arm, typically on the non-drive side of the bike. You can also opt for a dual-sided meter (left and right) for more accurate readings. Alternatively, the entire crank arm can be replaced with a compatible model that has a built-in sensor.

Easy Installation: Bring your bike to our shop and we’ll take care of sending the parts directly to 4iiii for a fast and professional installation.

Advantages:

• Great value for money

• Quick installation on your current crankset

• Lightweight and discreet

• Compatible with most crank arms

Estimated budget: Starting at $450

Option 2: Install Pedals with Integrated Power Meters

Some pedals—like the Garmin Rally or Favero Assioma—include highly accurate power sensors. They’re easy to install and can be swapped between bikes, making them ideal for cyclists who own more than one bike. These are available as single-sided (left only) or dual-sided (left and right) models. You can also choose a platform that matches your riding style: road (Look Keo or SPD-SL) or gravel/MTB (SPD).

Examples available in-store:

• Garmin Rally RS (Shimano), RK (Keo), XC (Gravel/MTB)

• Favero Assioma Uno

Advantages:

• Easy installation with no special tools required

• Perfect for riders who use multiple bikes

• Dual-sided power measurement (depending on model)

• Compatible with road or off-road riding

Considerations:

• Higher cost

• You may need to change your cleats if switching pedal systems

Estimated budget: Between $699 and $1,400

Option 3: Choose a Bike with an Integrated Power Meter

If you're already thinking about buying a new bike, choosing one that comes with a built-in power meter can be a smart and seamless solution. More and more bikes now include integrated sensors—SRAM groupsets often come with them, and some Cervélo models equipped with Shimano include 4iiii technology.

Advantages:

• Fully integrated, clean look

• Highly accurate data

• No compatibility or installation concerns

Estimated additional cost: Between $800 and $1,500, depending on the model
