AeroPod, PowerPod and Newton

Thooey,

Sorry for the bum steer, Thanks to John for the straight scoop!
I am an old man and my memory works when it wants to, usually at the wrong time

Ken and George and all, I have only four profiles for the unit which simplifies. A workaround for me has been to, first, label the profile number in the title in the edit profile list. Second, when I want to download a profile, I select the active profile in the Newton first and it goes by default t...

Hi thooey, I took a look at your ride with Isaac and tried the tool/repair for missing cadance. Well the power for the repaired section went out of sight (unless you are a very high end rider) but did not seem reasonable to me. So I have no clue about that, I wonder if the strava power data captured...

Hi George, Hard reset does not delete those things or anything that I know of. It does reset the date to a production date of some kind. So, if you do mid ride for some reason, you might want to go into setup and set date/time approximately at least. Of course you will end your ride with two ride fi...

Hi, I saw the iBike Facebook recent Feb 11, 2015 posting a YouTube video by Brian Toone and watched it with interest. Well I was curious and Googled Brian Toone and here is his web site which is currently showing a Isaac screen report on his bike race, very cool! http://toonecycling.com/ Enjoy, Russ...

I would suggest using some form of editing on the GPX file to give it the same start time as your ride after the cal ride. I am only familiar with Garmin edit capability in the PC app but I expect you can find something. Maybe someone can chime in with an application suggestion or google know so muc...

Barry, Besides changing your profile, I believe John is suggesting you can post analyze that ride you mentioned with a tweeked CRR. In other words, use the analyze/ return to original download choice then choose tweek values and change the CRR to the .008 and observer if the power levels appear more...

Hello EHB, I took a look today, waiting for the roads to dry :-) I did a return to original download and then did a check cal without the DPFM, then I cancelled that and did a check cal with DPFM and both are close to each other. Your wind cal would seem to be close enough, unless the wind changed d...

Wow, I just went back and scrolled along through the ride, zoomed in. It becomes apparent that your positive and negative slopes are power related in appearance! Maybe you knew this already. 0-200 w Negative slope 200-400watts balances positive/negative 300-500 aprox 2/3 positive 300-up all positive...

Davidson_ibike.jpg I find this an interesting view. I don't know track details but is the up and down slope properly unequal for the track? If not, then bike tilt correction may be off, of course dynamics of high and lower power may skew the tilt too. Other wise It looks reasonable to me (maybe I s...

Hello Pete, I have taken a quick look and two things jump out right off, wind looks unbalanced on the high side and your cda looks really quite a bit below average. So I tried 'return to original download' followed by a check calibration, this is the significant part: Aero 0.292 -> 0.231 Wind Scalin...

Fernando,

You said:
"Perhaps you should split the file into threes, work on the middle section and then unite them."
Interesting idea! I may play with that some, after I read your provided links.

Really appreciate your time,
Thanks,
Russ

Sorry, I can't resist qualifying my post, cannot be unless you have warp drive wheels :D From your advances stats: Rolling -225 -119.9 -0 W CdA: 0.373 m^2; Crr: -0.0156 Now if you tweek your CRR to .005 (typical) you get this in advanced stats: Power 0 259.1 1084 W Rolling 0 38.4 72 W CdA: 0.373 m^2...

Hello danhulbert,

I just took a quick look at your file and your negative CRR value jumped out at me. That cannot be correct.

Regards,
Russ

Fernando, I really appreciate your 2cents worth as being quite a bit more in value! And no problem with delay, especially understandable with the Christmas and new year holidays (happy New Year!). I agree on the 46km ride, not worth the effort, but there, I think it did improve accuracy because my w...

Zoltan and all, Full disclosure here, I have nothing to hide when it comes to odd :-) Here is a picture of one of my failed iBike experiments. The objective was to measure my breathing rate during a step test to find my ventilatory threshold. The VT is said to be quite close to the lactate threshold...

Dear friend Zoltan, I did not mean to hurt! Please forgive me. I have enjoyed the ideas of how to use the beloved iBike in ways not intended by Velocomp and you have certainly contributed great ideas, perhaps my unlimited imagination needs some reasonable limits! I think we both would love for a few...

zoltan, That looks really neat on your new boot, glad that works out for you. Now given Ken's point and if you still want wind data, think more about the trailer idea. If the wheel is not too large, you can double even triple or quadruple the circumference that you tell the iBike is the case. This i...

Zoltan, I have an idea you might try. Purchase one of the hand held wheel distance measuring devices. You may have to extend the handle some way and mount it like a trailer from your belt, probably attached to both sides for stability. Then mount the magnet, sensor and iBike back on your 'trailer'! ...

Hello Zoltan,

I have a possible solution but you may reject it.
With the Newton mounted on top of your hat:
Place a magnet on one boot and a speed sensor on the other!
Trouble with that is to get the data you want you may need to keep a
high cadence :=)

Russ

Fernando, These are 'corrected' as discussed above. I expect they should be as original when you select analyze - return to original download. I do not have auto correction selected. This is why I suggest taking note of the points of correction before returning to original to see the difference made...

Jose and Fernando, Here are two examples of my tweeked rides. Yesterday's ride first, without applying about half of the wind correction that Isaac calculated, nearly all of the wind shown was on the high side. The wind died to zero nearing the end of the ride. During that period there was a clear n...

raceferen, Thanks for the advice, I really need it this morning :) But actually and seriously, with a look at the local personnel weather stations around and the tables of wind measurements, along with studying the wind display is Isaac, sometimes I think an educated guess is likely to improve accur...

tesmurphy and racefern, I do normally use the route correction as it is rare that the barometric pressure stays same over my ride and if the wind wasn't steady (normally the case) check the 'wind changed' box. This way it will only correct the elevation and if I find that the wind dropped of rose on...

Pete, Nice link. I played with it and you are correct 90 degrees of crosswind has some effect. However at 97 degrees and a bike speed at the default of 40kh, the effective speed was 40.03, really not much. So at some angle of cross wind and speed, it is nill basically. The removal of wind in Josej f...

Josej, It is interesting that if you select that portion and use the correct for blocked wind sensor repair tool, accept wind as zero, then your average watts for that section rises from 218 to 290 watts or so. I think, if the wind is exactly 90 degrees off center perhaps that is justified since it ...

rstrom and iBike, I have seen a very similar occurrence once. In my case, after not finding the sensors for awhile, I went into setup and the profile was sitting on a different one from the bike. I had not changed bikes since prior ride. So I then manually selected the correct profile and off I went...

Thanks to Tom Gore and John at iBike! I sent my Newton back at Tom's suggestion. He said they would open it up and check it over (for hw updates, I guess) and also fix the serial number problem. Well they turned it around quickly, fixing the problem and for free. Great service iBike!. Thanks, Russ

OK, I fired up an old laptop that has xp and 2.5 Isaac on it and fixed my profile in the Gen 3. Now after today's ride..... Guess what? The exact same pop up complaint appeared at the end of uploading my ride. Except it did receive the ride into Isaac and after complaining that the weight was outsid...

Hello Velocomp, I dusted off my b/u Gen 3 iBike as I am packing my Newton+ to ship to Tom Gore for service. Yesterday I took it for a ride and ran the check calibration function to correct the wind scaling, which was the only change When I clicked send to iBike, it popped up an error: Following para...
