7. THE NEWTON POWER METER WORK The iBike Newton power meter uses a revolutionary approach to power measurement that is based on Newton s third law For every action there is an equal and opposite reaction In bicycling terms this means that the factors causing the cyclist to expend power during a bike ride hill climbing opposing wind tire bearing and other losses bike acceleration are equaled by the power applied through the pedals by the rider With the exception of the Newton all other high performance power meters determine power by measuring the forces applied by the rider to the pedal Directly measuring applied pedal force is an accurate way to derive power provided the cyclist is willing to accept the weight cost installation inflexibility and operational penalties that are characteristic of a direct force power meter DFPM In radical contrast the Newton uses state of the art sensors along with new and patented technology to measure the opposing forces that cause the cyclist to expend power opposing wind hill climbs bike acceleration and rolling friction of the bike and tires A powerful microprocessor programmed with proprietary DSP filters and real time solutions to the dynamic power equation processes the output from the Newton sensors many times per second computing the total power demands created by hill slope wind etc And thanks to Newton s third law measuring the power consumed by hill climbing
8. baseline that characterizes your current level of fitness This reference point is called your Functional Threshold Power or FTP One way to determine your FTP is to do a one hour Time Trial your average watts for that one hour period is your FTP Another way to estimate your FTP is by using the Newton s 20 minute fitness test The Newton 20 minute fitness test is similar to a time trial just shorter in time To estimate your FTP from the Newton fitness test take the watts per kilogram number shown in your FIT TEST screen multiply that number by your weight in kilograms then multiply that number by 0 95 For example if your W KG measurement is 3 02 and your weight is 81KG then your estimated FTP is 3 02 81 95 233W Once you have determined your FTP number from either method you must enter that value into the Newton Go to Setup FTP CFG FTP Configuration Click the center button then use the arrows to enter your FTP in watts Click the center button to Accept If you re training regularly you ll want to check your FTP about once a month Normalized Power NP Have you ever participated in a group ride where your watts are never steady Group rides can be very difficult but afterwards you might suspect that your average watts don t accurately reflect how difficult the ride was The disparity between measured and perceived effort is due to coasting surging using brakes and soft pedaling In fact your averag
