- Page 5 STEP ONE: INSTALL THE LATEST VERSIONS OF NEWTON FIRMWARE AND ISAAC SOFTWARE PowerStroke requires that your Newton have firmware version 3.0 (or higher) installed, and that your Isaac software is version 2.0 (or higher). You can obtain the most current (and free) firmware and software upgrades using your Isaac software: Firmware 1.
- Page 6 STEP TWO: PURCHASE/INSTALL POWERSTROKE NOTE: IF YOU HAVE PURCHASED AN IBIKE NEWTON POWER METER WITH THE POWERSTROKE KEY PRE-INSTALLED, SKIP THIS STEP AND PROCEED TO STEP 3! 1. Purchase a PowerStroke Key from the iBike Store. 2. You will receive an email from Velocomp, instructing you to email the serial number of your Newton.
- Page 7 7. Click the “Upload” button 8. It takes just a few seconds for the key to be installed. At the end of the installation, you’ll see a message saying that the PowerStroke feature has been installed. 9. Download any ride files stored on your Newton. Erase your ride data from your Newton.
- Page 8 STEP THREE: SET POWERSTROKE RECORDING TO “ON” TIP: After installing your PowerStroke key, your Newton is automatically set to record your ride files in PowerStroke mode (“ON FAST REC”). You can check if your Newton is in PowerStroke record mode, in either of these two ways: WHEN WAKING YOUR NEWTON FROM SLEEP Whenever your Newton is awakened from sleep, AND your Newton is set to...
- Page 9 TURNING POWERSTROKE RECORDING OFF For long rides, or when doing starting a ride where your Newton’s memory is nearly full, you will want to turn PowerStroke recording “Off”, so that you don’t run out of ride memory during your ride. When PowerStroke recording is “on”...
- Page 10 STEP 4: SET CADENCE SENSOR POSITION PowerStroke ride files include information regarding the mounting position of your cadence sensor on your left chain stay. After downloading your first PowerStroke ride, Isaac will prompt you to state where your cadence sensor is positioned on your bike (“Above” or “Below”...
- Page 11 USING POWERSTROKE ON THE ROAD Hi-speed PowerStroke recording works “behind the scenes”. When in PowerStroke mode you won’t see ANY differences in the on-the- road operation of your Newton, EXCEPT that your ride memory will fill much more quickly. Why does memory fill quickly? In PowerStroke mode, your Newton records sensor data at high speed, 16 times per second, instead of the usual “one time per second”, or “one time per five seconds”...
- Page 12 ANALYZING POWERSTROKE FILES WITH ISAAC SOFTWARE NOTICE: PowerStroke files can be read only with Isaac software, version 2.0 or higher IMPORTANT: WE STRONGLY RECOMMEND YOU READ THE APPENDIX, WHICH PROVIDES DESCRIPTIONS OF THE CONCEPTS AND MEASUREMENTS THAT ARE DISCUSSED IN THIS SECTION In these instructions we will concentrate on features unique to PowerStroke;...
- Page 13 Displaying PowerStroke Wasted Watts in Main Window PowerStroke Wasted Watts can be displayed in the main window, as follows: 1) In the main window, touch the “Show” button in the top right of the main window. This window will appear: 2) In the bottom left corner, select the “Wasted Watts”...
- Page 14 The PowerStroke Window In these instructions we will use the “Sample Ride” file (located in the Help menu of Isaac) to illustrate PowerStroke functionality. To see PowerStroke stats for the entire ride file, click the PowerStroke icon: To analyze PowerStroke information for a selected portion of the ride, while in the main window, highlight the portion of the ride you want to analyze, then click the PowerStroke icon NOTE: FOR BEST QUALITY OF POWERSTROKE ANALYSIS, SELECT AT LEAST...
- Page 15 Here is the PowerStroke window for the entire ride: NOTE: IN THE “WASTED MOTION” PLOT AND “RIGHT CRANK” PLOT, RIGHT STROKE INFORMATION IS COLORED IN PINK. LEFT STROKE INFORMATION IS COLORED IN LIGHT BLUE. NOTE: CLICKING THE PLAY (>) BUTTON IN THE LOWER LEFT CORNER CAUSES THE WASTED MOTION AND CRANK VIEW PLOTS TO ANIMATE.
- Page 16 There are four sections to the PowerStroke Window. Each will be described individually. WASTED MOTION PLOT The Wasted Motion Plot shows the motion of the bike, relative to the center of mass of the rider, both side to side, and front to back, as the cyclist pedals through a complete turn of the crank.
- Page 17 Crank Stroke Plot All cyclists know that their bike is propelled down the road by the power (Propulsion Power) they apply to the pedals. And many cyclists know that the bulk of their propulsion power comes unevenly during each crank stroke—only a small portion of their propulsion power is applied at the top and bottom of the crank stroke, and most propulsion power is applied between.
- Page 18 Reading the Crank Plot Here is a snapshot of the crank plot Here’s how to get the most out of the Crank Stroke plot: 1) The Crank Plot shows the pedaling motion of the cyclist as the crank turns, as viewed from the right (gear side) crank 2) Clicking the green Play (>) button at the bottom left animates the Crank Plot, and also the Wasted Motion plot 3) The cyclist’s actual front-to-back movement is represented by pink...

- Page 20 WATTS” ; “IDEAL MOTION”; PROPULSION POWER PowerStroke includes iBike’s exclusive measurement suite of front-to-back and side-to-side wobble motion of the bike, and the Wasted Watts, Motion, and Time caused by wobbling. This appendix discusses concepts and measurements that are central to PowerStroke.
- Page 21 Propulsion Power It takes power to propel the bike/rider down the road. Power meters measure propulsion power. Propulsion Power is reported in the PowerStroke Stats Box, and is the same as the “Average Watts” number reported in the main window of Isaac. Wobbling and Wasted Watts Wobbling requires the cyclist to expend energy (watts) to power the wobble—that’s Wasted Watts.
- Page 22 Is all wobbling “bad”? Of course not! For example, in a sprint, side-to-side wobbling is extreme— producing huge amounts of short-term power, but at reduced economy, due to wobbling. And even when not sprinting, some amount of wobbling is both natural and normal.

TROUBLESHOOTING Problem: I don’t see the PowerStroke icon in Isaac Possible causes: 1) The version of Isaac installed on your computer is not 2.0 or higher. Use the Help/Check Online for Software Update…feature to obtain the latest version of Isaac. Problem: In Isaac, when I click the PowerStroke icon, I don’t see any PowerStroke data Possible causes:... - Page 24 Problem: My Crank Plot looks OK, except my power pulsations seem to be at the wrong angle Possible causes: 1) You have not set the Cadence Sensor Position in your Profile. Problem: My power readings are “off” Possible causes: 1) This has NOTHING to do with your PowerStroke features! Consult your Newton Instructions for troubleshooting tips.
