IQ2 Power Meter

looks like a rough start for the testing

https://www.strava.com/activities/3297091670/analysis

Since I don’t do Strava, I only saw the elevation gain and the comments. Though this is not promising. Will see what they do with it.

Only half the ride at best even has power data, not a great start

Maybe @dcrainmaker coasted for 18 miles or so…

Lots of downhills over there :stuck_out_tongue:

38m of elevation ought to be plenty

Or he’s mechanical juicing

It’s not the size that matters, but how you use it.

As I often ride the same routes I can confirm that the elevation gain is accurate… sometimes I come back home and see 100+ m of elevation gain and wonder what happened, until I realised I forgot to turn off the head unit and at least 30 m are from the elevator ride to my apartment :stuck_out_tongue_closed_eyes:

Most of my elevation gains in The Netherlands are due to increasing temperatures throughout the day and the lack of my garmin to correctly interpret the resulting decrease in air pressure. :laughing:

Looks like I’ll hold off on my pre-order a little longer!

Pure stud right there.

When are we going to see your impressions and evaluation?

They picked it up yesterday to investigate. What was occurring was crazy weird, and honestly, I’ve never seen any unit do what it did in all the years of testing of power meters. And they were pretty honest too they’ve never seen that issue before. It was as if someone had a volume dial on my power, and would slowly turn it down till I stopped. If I stopped, then I’d get ā€˜volume’ (aka power) back again…for a few minutes, and then I’d get my volume turned off again. Crazy weird [Also, the most awesome idea ever for a Zwift Racing hack of a competitor].

This was dual-recorded on both a Garmin Edge 530 and a Wahoo BOLT. So definitely not a recording-side issue.

They’ve got all my data from the ride and videos as well. They’re hoping to have either a new unit to me tomorrow or Friday, or my previous unit back. There’s little point making an impressions post/video on a single ride that obviously something is seriously broke on that unit. They did seem legit ā€˜WTF?!?’ in our discussions (in a good way).

So hopefully I’ll have another unit by weekend I can start putting it through its paces. Initial brief testing (a few mins) on a trainer before I headed out looked fine. And most of the first 20 minutes didn’t look bad either.

As I said before, what I saw I’ve never seen before. In all the list of ways power meters can ā€˜fail’ my testing, this wasn’t one of them. Which honestly, I think is a good thing (as weird as that may sound). Mostly because it was so weird I don’t think it’s something they would have overlooked in testing - and thus hopefully is just a single bad unit.

Interesting. It’s sounds like a power (electrical) issue like when a battery drains until it stops, then after a while it has a bit a charge and it goes a little bit again.

They probably screwed it up making sure it was right for you.

Competition heating up…

Not really competition just on price. If iq2 aren’t reliable/accurate/available then I’d go for crank or no power meter. 5 times the price really puts them out of reach.

If iq2 fails looking at the interest generated hopefully someone else will try for SPD options. A collaborative effort with Xpedo and Assimo would work with very little effort on their behalfs.

Only five times the price if you bought in the Kickstarter. 3x the price as it stands, which yeah, is still crazy… but it’s a product you can actually buy!

Is the IQ2 supposed to be more accurate than that? I couldn’t see any accuracy claims on their website.

Edit - I see it on their Indigogo page. 1% will be cool if they can achieve it.

IQ^2’s response to the issues @dcrainmaker saw last week. Sounds like they found a cold solder.

ā€œLast Monday we delivered our first power meter to DC Rainmaker, planning to send another power meter to GP Lama soon after. On Tuesday, DCR rode with our pedals and got some consistent power readings until he encountered an issue he nor we had ever seen before. Luckily DCR lives nearby, so we decided to pick up the pedals to test them at the office. Back at the office we tested for days and didn’t encounter any issue. But finally, we found a solder mistake on the PCB was the culprit. Clearly, this is a singular issue for that particular power meter. We will bring a new power meter to DCR this week and also ship one to GP Lama.ā€
