About the PowerTap G3 Hub Power Meter

PowerTap is known for their hub-based power meters which have been on the market for over 15 years and have a reputation of being reliable, accurate and trustworthy. The company is currently on their third generation of power meter hub, the PowerTap G3. The PowerTap G3 Hub Power Meter is used in replace of your current hub and is able to deliver +/- 1.5% accuracy and transmits both speed and cadence data as well. You can purchase a stand-alone hub, or one that is pre-built into a completed wheel set, making installation a breeze.

Why the PowerTap Hub?

Priced Right

At $399, the G3 offers accuracy, durability, ANT+ and Bluetooth SMART – all from an established power meter manufacture with a reputation of making top-notch products.

Quick Installation

If you buy a completed wheelset, installation is about as easy as it gets. All you need to do to is install the wheel in your bike and you’re good to go.

Easy to Use

In typical PowerTap fashion, the G3 Hub is easy to use. Spin the cranks to wake it up, perform a quick zero and you’re ready to go!

ANT+ and Bluetooth SMART

The PowerTap G3 Hub is both ANT+ and Bluetooth SMART compatible, so the power meter can be used with your cycling computer or smartphone.

Only Hub-Based Power Meter

PowerTap is the only manufacture of a hub-based power meter – so the choice is easy when looking for hubs.

PowerTap G3 Hub Options

    The Powertap G3 hub serves perfectly to a rider introduced to power meter training for the 1st time. The price has gone down and more affordable now. I use it both for indoor and outdoor training. Trainer Road and my Garmin Edge detect and connect to the G3 hub flawlessly.
    Power meters are not easy to get in my country and I’m glad Power Meter City international free shipping make that possible. Also, the tons of power meter information and guide from this website has no equal.
