Re: Geoid PM500 power meter
I bought one today’s morning from geoid store when it was for around 220$. Now price increased and it’s not much cheaper than pes515 so for now it has no advantages over magene’s. Hope it’s going to be delivered not canceled. I am also wondering if it’s going to be Chinese version with no app connection but since I bought it from official store I hope there is chance of unlocking it like pes505. I asked Geoid this before buying and got this answer: ”Hello! The GEOID PM500 power meter is fully compatible with European use and does not have any regional restrictions. It works with all major cycling apps and computers including Garmin, Wahoo, Magene, iGPSPORT, and Bryton, regardless of region. The power meter uses both ANT+ and Bluetooth protocols, which are universally compatible across all regions. You can use it with any compatible cycling computer or app in Europe without any limitations.” November 01, 2025, 07:34:12 AM |

Re: Geoid PM500 power meter
I got the power meter. It's a bit heavy at 668 grams, but that's still okay. The Magene app works and recognizes it. November 16, 2025, 12:36:34 AM |

Re: IGPSPORT Binavi Air
I just created a fit file and sent it to my BiNavi Air through the App. According the user guide, (connect BiNaivi Air to APP tap on the yellow small icon, right low corner of device picture) Tap: Specially Function - Select: How to calibrate the elevation.Then it reads amongst more: Auto calibration of height is done through GPS. This will be updated 5 min after GPS connection February 16, 2026, 02:36:31 PM |

Re: Geoid PM500 power meter
I tested the PM500 against my Tacx Neo 2T a while ago and posted the results on Reddit and wanted to post the results here as well but had trouble logging in. Anyway, now that I've managed to log in, here are the results. I installed a Geoid PM500 on my gravel bike thinking (hoping) it would offer the performance of the now discontinued Magene P505 at a lower price as the Magene is well proven and I'm happy with mine on my road bike. However, I have not seen much testing of the PM500, so I decided to do a quick and dirty test of mine against my Tacx Neo 2T by comparing the two fit files using compare-the-watts.com Results (with 2 seconds offset and 1second smoothing): Overall  Some low power steps in ERG mode (the slope is the Neo 2T not adjusting resistance fast enough to compensate for me raising the cadence)  Higher power steps in ERG mode  1st 1000+ watt effort in free ride mode  2nd 1000+ watt effort in free ride mode  3rd 1000+ watt effort in free ride mode  Observations regarding the PM500: - Tracks the Neo 2T pretty well overall. - No fumble after 1000+ watt efforts (seems to be the pitfall of many power meters tested by Mr. Lama, including the latest crop of affordable models, unfortunately). - Seems to be more responsive to sudden power increases (always felt the Neo 2T felt "smoothed" compared to my P505 ridden outside). - Several drops in cadence can be seen, but I don't know if it's some sort of glitch, connection issue or the meter picking up drops in my not very smooth pedaling (linked to previous point?), but there doesn't seem to be any corresponding drops in power, weird. - There is a drop in power between the 28th and 30th seconds in the 3rd 1000+ watt effort, but no cadence drop, again, weird (linked with the 2 previous points?). I'm happy with the results, it's close enough to the Neo 2T and doesn't exhibit offset problems after higher power efforts. Installation is very straightforward, just like a Shimano crank, simpler than the Magene PES P505. The most negative point about this power meter (and other Magene spider power meters) is the crank interface, I wish it were Easton compatible. I hope this post was of interest to those shopping for affordable power meters
