Re: How to get raw ride data?

Exact same thing happened to a different friend of mine on a ride today... It has happened multiple times to these two guys...

It appears to be impossible to recover the original data to demonstrate the problem; the software always seems to correct for it. I have attached an example.

Re: How to get raw ride data?

Gotta disagree about it being a bug; the iBike shouldn't start recording before it is finished its startup sequence.

Just my opinion, but the unit should know this and not require the user to do it. I am unaware of any other cyclometer that has this problem (AFAIK).

Just my $0.02

Re: How to get raw ride data?

Well, if that's what was going on then I would expect the distance to be a tad low (probably too small to really be detected).

But what is happening is the opposite. A Huge over-measurement.

Thanks.

Is this a bug with the sensor or with the iBike unit?

How to get raw ride data?

A friend of mine has experienced (a couple of times) an odd thing where during his ride it would all of a sudden show that he rode a huge distance when he hadn't. For example, yesterday at mile 40 (for us) we averaged about 18, his unit showed he was at mile 126 and had averaged 28mph. I wanted to l...

When remounting, do you need to re-cal?

I assume it is pretty easy to take the mount off if you don't want to use it.

But if you remount it I am guessing one would need to do another calibration ride?

I assume you don't if you are just replacing the recharged battery...

Nope, no work done. Headset still nice and tight.

Besides, if it were just a tad loose I might expect small changes, not those HUGE jumps.

Re: Can't calibrate ride?

Any chance of getting it tweaked to be closer??

Also, I have another bike I would like to use. I am trying to get it to be as similar in terms of weight, fit and position on the bike as the one I am using now. What are my options since I can't seem to get a reliable calibration?

Re: Can't calibrate ride?

The entire ride was a group ride. I did get a good wind calibration to start, and then re-did it around mile 30 when we stopped. When I apply this profile to the ride (after the ride) it looks like it is showing 10% lower power instead of 20% lower (by my eyeball calculation). Certainly better, but ...

Seems like that would be a nice software feature; analyze iBike profile compared with DFPM measurements (over the course of a ride of course)

Re: iAero as head unit for Quarq

So, just to be clear, all power related display on the bike would be based on the DFPM (like NP, TSS, etc)?

Re: Can't calibrate ride?

Do the numbers in the profile look good to you?

And is it worth re-doing the cal ride using a 1sec sampling rate and doing some coast downs?

Re: Can't calibrate ride?

Cool, so the iBike already has the new profile loaded? My power numbers looked better than before, so I wanted to apply them to some recent rides...

And thanks John.

Can't calibrate ride?

So, I did a successful calibration ride, however when I try to load it into the software, I select the portion of the ride that was out and back, but the calculate button on step 4 of the dialog is always grayed out.

Any ideas?

iBike Aero III w/Garmin speed cadence sensor issue

So, my unit is suddenly showing me calories instead of cadence. I know the speed/cadence sensor is working because of the wattage it is showing me only when I pedal.

Any ideas (sorry if this is a FAQ, couldn't search for it).

I have experienced this a few times now and it is a bit annoying. Basically, I start my ride out with a good wind calibration. I even validate it before I start riding.

OK. I have attached my cal ride with 8 coast downs. The surface was pretty smooth, byt the Crr seems pretty low.

Coast downs in addition to a cal ride?

If I have already done a cal ride, would coast downs help get a more accurate profile? If so, what additional work is done with a coast down (what aspects of the profile would be improved)?
