The Newton 5 is the world’s only power cycling computer that includes everything you need to train–and win–with power.

And at $499, it is the world’s most affordable power system.

Only the Newton 5 has a microcomputer that delivers power measurement, power training programs and power testing in one super-light unit, with the easiest-to-read display around.

We’re often asked, how does the Newton 5 work?  Where are the strain gauges?  Simply, the Newton 5 uses advanced accelerometers and pressure sensors from the space program to measure your power.

The Newton 5 is a power meter and more.  It is a world class cycling computer.  It is incredible software.  It is a personal trainer that tests your limits and then improves them.

All in one unit.  All for one purpose.  To help you get more results and more fun in your cycling.




Newton 5 technology was introduced at Eurobike 2014, and adds these 5 exclusive features:

  • User Configurable Screens
  • Dynamic Power Smoothing
  • Automatic Profile Selection
  • Send Newton Power to ANT+ Bike Computer (“GT”)
  • Simplified Setup and Calibration

Every Newton shipped after October 1 2014 includes Newton 5 technology at no extra charge!

If you’ve never trained or cycled with power, you are missing out on the most important accessory you can have on your bike.  No other bike component–wheels, frame, helmet, you name it–will improve your cycling as much or as quickly.

And no power meter offers you as much capability and flexibility as the iBike Newton 5.

We are so confident that you’ll love the iBike Newton 5, and so convinced that you will love training and riding with power, that we offer all of our website customers a no risk guarantee:

Try the iBike Newton 5 for 30 days.  If for any reason you don’t like it, return it in good condition for a full refund.  Details are here.

Sure, you can spend much, much more to try out a power meter.  But we are not aware of ANY competitor that lets you try theirs risk-free.



One of the most frequently asked questions about the Newton 5 is: how accurate is it?

Superb accuracy begins with sound technology and engineering.  Here is a section that talks about how the Newton 5 works.  People who have studied the Newton’s technology–engineers and physicists in particular–are amazed by its robustness.

We have 10 years of customer testimonials…you’ll find them on Facebook and elsewhere.

We’ve had lots of independent reviews. Here is a detailed independent review, published in the February 2014 issue of RennRad, a prestigious cycling magazine, written by a PhD, comparing the Newton 5 to SRM, PowerTap, Quarq, Polar, and Garmin.

The reviewer’s finding? The Newton 5 was within 2% of the SRM, at 1/5th the price.

SensorImageThe iBike Newton 5 uses 21st century digital sensor technology.  The Newton’s accelerometer and dynamic pressure wind sensors—both used in aerospace applications—absolutely nail the power a cyclist produces.

Because the iBike Newton 5 sensors are “hard wired” to the main circuit board, iBike PowerStroke readings are recorded 16 times per second, every second! No other power meter gives this depth of data.

The iBike Newton 5 uses patented technology that does away with strain gauges and expensive hubs, cranks and pedals.

Complete cycling computerTraditional power meters require separate purchase of a bike computer.  You’ll also need to find software or a website to read the bike computer’s data.  And if you want to train with power, you will likely buy a book that tells you how to so…or hire a coach who tells you what to do.

We think there is a better way.  The iBike Newton 5 Power Cycling Computer is a complete system: power sensors, sophisticated bike computer, Mac/PC software, and power training workouts are all included.  There nothing else you need to buy or search for on the web.

  • Quick Set Up

We know you want to get out and get riding! So we’ve made setup the easiest ever, with videos and expert “wizards” in Isaac software

  • Rugged, Space-Age Sensors

The iBike Newton’s solid-state sensors are located inside the bike computer head–far away from spinning hubs, cranks, and pedals.  No moving parts means superior water resistance and nothing to wear out. No moving parts means no need for expensive, inconvenient, periodic “recalibrations” at the factory.


  • Easy to move from bike to bike

Switching from bike to bike is easy and affordable. Conveniently place a 2nd mount and sensors on your additional bike and all you need to do is slide your iBike Newton onto the mount when you’re ready to ride. Your iBike Newton stores 4 profiles for 4 separate bikes!

  • ANT+ compatible

iBike Newton uses ANT+ technology, so you can use any Garmin speed/cadence sensor and heart rate strap–or any other ANT+ sensor! The iBike Newton also reads power data from any ANT+ direct force power meter.

And optionally, you can transmit your Newton power data to any ANT+ bike computer.

  • Mac and PC compatible

iBike Isaac software is feature packed and easier than ever to use. A click of the button shares your ride exploits on Facebook–or click a different button and send your ride file to TrainingPeaks or Strava.

If you ride with an iPhone or Android smartphone,  Newton Tracker adds full GPS and STRAVA capabilities to your iBike Newton.

The free Newton Tracker app (available at the App Store or the Google Play Store) runs in your smartphone’s background (for more than 10 hours) and records your GPS data.

When you download your iBike Newton ride in Isaac software, Isaac “pulls” your smartphone GPS data from the cloud and magically adds it to your ride.

View your ride in Google Earth, or send your ride data to your STRAVA account.

Superior Reliability begins with Superior Design

Newton_Black 05Read about any other power meter design and you’ll find concerns about adjustments, water seal integrity, temperature variation, glue failures, and periodic factory recalibration.

The iBike Newton’s 21st century design does not have any of these concerns, because it has no moving parts and because it uses the same durable sensors used in aerospace applications.

Reliable, Fully Rechargeable, Winter-Ready Battery

With 4 times the capacity of the original iBike battery, iBike Newton rechargeable battery is ready to roll!

Sensors and batteryWeather can’t stop it – the iBike Newton battery is fully enclosed. And in 20 degree weather the Newton’s battery life far outlasts any rider’s stamina.

The iBike Newton battery lasts up to 20 hours of ride time, and recharges quickly from any computer USB port or USB charger.

Rugged, Secure Mount

NewtonMountsThe iBike Newton’s mount has been designed for superior reliability.  A metal bolt secures the iBike Newton to the mount, providing safe and rock-solid performance of your Newton, no matter how rugged the terrain.



The iBike Newton’s capabilities begin, but does not end, with accurate power measurement.

Traditional power meters measure power and cadence. Nothing less, nothing more.

But because of the iBike Newton’s patented, built-in sensor technology, you get so much more!


  • Current, average and maximum:

    Wind Speed, Hill Gradient, Altitude, and Temperature

  • Snapshot CdA

    It’s like having a wind tunnel at your fingertips. Change ride position, change gear, change clothing–and measure the aero impact!

  • PowerStroke

    See your wasted motion, both front-to-back, side-to-side, and left to right. As you improve your pedal stroke, PowerStroke will quantify the improvements.

  • Drafting analysis

    See when you draft, when you pull, how often you pull. Quantify the power differences. See if your race tactics are working or not.
