I am gonna buy a gas powered fork bike nothing classi, chose mostly for offroad and speed, So ive been told it goes 20/25 but people have told me they can go up to 65 , im confused please help , thanks. Let me put it another way. 700 watts is a measure of power and that is not directly related to speed. Racing?There are two "naive" pacing strategies (let's think about a 40K time trial, just for sake of argument).
Is there a chart from say 0-40 MPH, with wattages for all of them? Highly inefficient for what? However just for the hell of it I'll pretend this thread has a sane future Training?
but it is 10% of a bigger number, so the power needed is still more, if you ease off the power you will slow down! Answer. Or the other way 10mph headwind and you maintain 16mph by how much would you have to increase your power? (Not that I'm in any way implying it's docile!!!). what did you put in for the other variables (rider weight, bike weight etc) Or the other way 10mph headwind and you maintain 16mph by how much would you have to increase your power?Obviously a headwind would add nothing to your speed. 25 MPH?So I weigh about 150, 5' 6", standard road bike. Manc33 becomes interested in power numbers. You missed the point. Obviously a headwind would add nothing to your speed. Please correct me if I'm mistaken.The algorithm uses zero wind and flat road, which never really existsHas anyone ever solved the optimal racing strategy as a control theory problem?
Wiki User. Let me put it another way. based on the above and your hypothetical 100W at 15mph, just take the velocity, multiply by 2/3 then square. Find someone you can ride with who has a powermeter. If in zero wind you are riding at 16mph with a power of 100 watts, then you ride into a headwind of 10mph but still maintain 100 watts by how much will that headwind reduce your speed? The speed of an object is the magnitude of its velocity. If in zero wind you are riding at 16mph with a power of 100 watts, then you ride into a headwind of 10mph but still maintain 100 watts by how much will that headwind reduce your speed? I think that might actually be more accurate than using speed, because there is no flat, windless roads.Would you elaborate? Thats odd, at around 15-20 MPH each MPH gained takes around +15% more power. "In many ways, my story was that of a raging, Christ-like figure who hauled himself off the cross, looked up at the Romans with blood in his eyes and said 'My turn, sock cookers'"Well, it takes me more like 180w to average 15mph on a ride.

Have a look for an iPhone app called bike calculator, it gives very good estimates of wattage for various gradients, speed, wind speed, weight and even position on the bike. I need a chart with all other variables factored in except it taking Ride next to them at a prescribed watt for 20 minutes or so and try to assign perceived exertion. Is it me, or if this mystical chart existed and was reliable would we all be wasting our money on power meters, when we could just buy a cheap speedo? Top Answer. I am starting training for a time trial.You can't comprehend how much energy is wasted by accelerating too hard too fast or using too much effort up a short hill. I'm confused by the unusually reasonable and bike-related nature of your query. But that doesn't account for the loss of watts from a poorly indexed front mech and rubbing quick links. 25 MPH? You’ll still get plenty of gears for most road riding, but you won’t have quite enough high gears for when the speeds gets very fast, like 26 mph to 30 mph or faster. 2016-12-27 17:33:30 2016-12-27 17:33:30. The aero drag force acting against you increases with your speed squared, i.e. How Fast Is 700cc In Mph Units Sold: 18. You missed the point.
I just read somewhere "It takes 100 watts to do 15 mph on level ground". Or the other way 10mph headwind and you maintain 16mph by how much would you have to increase your power? You need to also account for rider weight and bike and so forth. How long is a piece of string? What difference would there be if riding into a head wind of say 10 mph? 0. I would expect it to take into account the physiological behavior of the rider (e.g., recovery time after cracking) as well as the non-linear effect of air resistance. I just read somewhere "It takes 100 watts to do 15 mph on level ground". I used to believe it was, but I don't any more. In simple, Speed is a way of measuring how quickly something is moving or being done. I am just curious, too cheap for a power meter at this time.
Preliminary readings show 800 watts at 27 mph, 1000 watts at 30 mph, and 1200 watts at 33 mph. Top 13 Best Comfort Bikes Reviews In 2020 it moves fast (up to 15 MPH… It depends on how fast you want to … The first naive strategy is constant speed, the second is constant power.
