In this equation, torque characterizes the amount of force or effort a rider generates on the pedals, while cadence is measured in crank revolution per minute.
What is a good wattage for cycling?
No exact watt number is appropriate for all riders. Generally speaking, a beginner cyclist may average around 75–100 watts in a 1-hour workout . A fit participant will average more than 100 watts, and pro cyclists can reach 400 watts per hour.
How is power measured on a spin bike?
The gears provide the force or resistance. Velocity is measured as cadence (or RPMs, revolutions per minute). Power is measured in watts, which is a measure of your exercise intensity in real time (looked at another way, it’s the product in the power equation).
How is cycling watts calculated?
The cycling power is measured in Watts. One Watt corresponds to one Joule of energy produced every second . cycling”. It assumes that the power you produce is equal to the sum of resistances you need to overcome, multiplied by your speed.
How does a power meter work?
Power meters typically work by measuring the force on a component (pedal axle, crank arm, spider) using strain gauges. They then convert this to power by multiplying it by the angular velocity (or cadence) of that component. As we’ve already covered, power is measured in watts.
How does strava estimate power?
When data from a power meter is not available, Strava can estimate power using information about an athlete’s weight, speed, and elevation change .
What is good watts per kg?
Generally, untrained riders have an FTP below 2.0 W/kg for men and 1.5 W/kg for women , while professional racers may be capable of sustaining more than 6.0 W/kg for men and 5.5 for women.
How fast is 200 watts on a bike?
Wind tunnel testing has shown that a 70kg cyclist putting out 200 watts of power would be traveling at 32.4kph if riding upright on the brake hoods. However, if the same cyclist were to go down onto his drops his speed would increase to 34.4kph.
What is a good FTP kg?
| World Class Pro Cat 4 and 5 | Male 5.6 – 6.4 w/kg 2.4 – 3.6 w/kg | Female 5.3 – 5.6 w/kg 2.0 – 3.1 w/kg |

Can you put a power meter on a spin bike?
Almost all spin bikes allow you to remove your current pedals and install new ones, and therefore, you could easily attach a set of power meter pedals . (Please note, these power meter pedals require the use of road cycling shoes). This is by far the quickest and easiest way to add a power meter to your spin bike.
How do stationary bikes measure watts?
A power meter on a bicycle is a device that measures the power delivered by the cyclist. Most bicycle power meters use strain gauges to measure applied torque and, when combined with angular speed, calculate power .
What is the 75 rule in cycling?
Follow the 75% Rule. The 75-percent rule states that during a given training week, at least 75 percent of your miles (or time) should be at or below 75 percent of your maximum heart rate (MHR) .
How many watts is 20 mph?
| Speed – kmh (mph) Power (watts) Increase in power needed to increase speed by 2.5kmh | 20 (12.5) 75 | 22.5 (14) 95 20 | 25 (15.6) 120 25 | 27.5 (17.2) 148 28 |

How do I calculate power?
Power is equal to work divided by time .
In this example, P = 9000 J / 60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.
How do you read a power meter?
What power meters do pro cyclists use?
SRM. Along with the SRM PC8 computers, the same two teams use the SRM power meters paired with Campagnolo groupsets. SRM invented the cycling power meter in the late ’80s, and has long been considered the authority on the subject. The SRM power meter used by these two teams claims an accuracy of within one per cent.
Is Strava Cycling Watts accurate?
the virtual watts from Strava are not accurate enough to worry about . If you want to get a feel for improvement, look at speed over the same course over time. There will be variance in that data due to wind etc, but it’s going to be a much better indication of improvement.
Is Strava estimated power accurate?
According to Strava’s algorithms I averaged 343 watts for this three hour ride. From many years worth of rides in the legs, I can confirm that Strava’s estimated power data ranges from “ somewhat accurate” to “wildly ridiculous” (and everything in between).
What is estimated power curve?
Power Curve shows your best average power for time periods of one second up to the length of your ride . We pinpoint your best efforts during a ride and you can compare them with your best efforts in the last six weeks, the current year, and years past.
What is a decent FTP?
The article claims that a typical fit cyclist might be able to crank out 250 to 300 watts as an average for a 20 minute FTP (functional threshold point) test, while the pros usually average 400 watts.
What does FTP mean in cycling?
FTP stands for Functional Threshold Power , which is defined as the highest average power you can sustain for approximately an hour, measured in watts.
Are lighter cyclists faster?
Even at the steepest grade he tested (7 percent), a one-pound difference between bikes only saves about 2.5 seconds—and the lightest bike only reaches the top 7.5 seconds faster than the heaviest one .
How many watts is 22 mph?
It says that based on someone 180 pound, 20mph is 162 watts and 22mph is 209 watts , so, an increase of 47 watts.
How fast is 750 watts in mph?
A 750w electric bike averages 27 to 28 mph on flat terrain.
How fast is 1000 watts in mph?
While it might not seem that fast when compared to driving, a 1000-watt e-bike equates to a speed of roughly 35mph .
