Hi, I’m attempting to adjust the power received from my indoor bike to more equal what I can do outdoors. I use a kickr bike which as I ride it… is 6-7 percent less than what I can do outdoors… I’m really only interested in using ebc indoors… is there some setting that gives the ability to “inflate” the numbers used? I want the feel indoor efforts to feel like the effort outside. I realize this could be down to some indoor riding style and not the readings from the kickr bike… but indulge me.

Hi Doug,
Good question. Have you compared your power meter directly to the Wahoo Kickr Bike, or is your 6-7% estimate a self-perceived difference? I’m not sure if Wahoo app has any power offset options… maybe you could check there to start?
I would also consider checking that you’re adequately ventilated indoors. Since you’re obviously not moving when training indoors, it makes evaporative cooling far less efficient indoors. If you’re dripping & drenched in sweat, you should reconsider your fans (& placement too).
Cheers!
No, I don’t think the wahoo app has that functionality. I do use two large fans! This is mostly self perceived, but I can never hit the numbers consistently indoors that I can outside (not even talking about max power). fortunately I can make this adjustment on Fulgaz but that means everything must be run through FulGaz . so I can’t seem to harness the goodness of EBC.
There is an adjustment under the individual power setting in EBC. I dont really understand the functionality of this setting as there is an overall ± setting on the main page of EBC. Can you clarify this?
Doug
+/- on EBC adjusts intensity of the workout under ERG control (AUTO mode).
While you could adjust in either direction the primary usage is to lower intensity if starting to fail interval sets. My preferred method is to switch to Slope mode and do the best I can. That may mean skipping an interval and inserting some extra rest time, but in Slope mode you can also exceed targets or insert “ghost” intervals of your own to make up for anything you miss.
There are ways to analyze the % difference in trainer vs power meter but one simple method is RPE based. Ride indoors on your outdoor bike (if not currently your trainer bike) and during a workout select Sensors and switch between Power connected to your bike power meter and trainer power. If they are substantially different you will feel it.
Use this Free Ride sub-LTP workout and switch Power back and forth over several minutes while using +/- to change intensity levels (watt targets).
For example, test at 100%, then 120%, then 150%.
If the difference feels substantial at each level you should consider dual recording to analyze the exact difference in watts/%. Ask for instructions if you’d like to do that.
If the difference feels marginal consider locating one of your fans to target your torso and head if both fans are currently floor based.
Do you consider your fans as high velocity or high volume? A small, high velocity fan will cool more effectively than a large, high CFM fan.
thanks, I’ll consider those. the fans are probably more large cfm than velocity. its hard to judge there effectiveness cause in the winter my basement is on the cold side!
