Re: Thinkrider PP5 power meter
On Strava: https://www.strava.com/activities/17369519118 Looking at the date log, one of the "zero watts" moments is on a downhill - could be coasting, not pedalling February 12, 2026, 08:51:01 AM |

Re: Thinkrider PP5 power meter
The main problem with us, who are shilling these cheap PMs, is that they do not fulfill its primary purpose i.e. reproducible (enough) power measurement. People may be looking at these PMs, not convinced by "good packaging, did not install yet" 5-star Ali reviews and thus guided to specialized forums like this. And if these folks read positive discussions, they may expect what is expected from a proper power meter i.e. reproducible (enough) power measurement. It is in the same realm as having frame with oval BB or group set that shifts 50% of the time. Does it looks like a proper frame/groupset? Probably yes. Can it be used for its main purpose? Most likely, not. At best you can assemble them together, put square wheels on the frame and call it an art object reminiscent of a bike. But it will not be a bike. Would such power meter show some numbers on your computer? Yes. Would you be able to track your progress? Properly pace your effort? Properly compare your intervals at 350W three months before and now, after consistent structured training, barely be able to squeeze 330W out of your legs (because your PM decided to drift 20W down on this ride)? Ride uphill at zone 2, go downhill and now your zone 2 is somehow substantially more difficult, because they did not manage to implement proper temperature compensation? I would love to get a really cheap power meter to be able to more easily swap my cranks and buy it for all of my bikes, but if it doesn't fulfill its dedicated purpose it cannot be called a power meter. It is power estimator. And I am fine with you buying power estimators. Just don't call it power meter for the sake of those who want to buy a proper power meter. February 13, 2026, 03:50:55 PM |

Re: Thinkrider PP5 power meter
I see a lot of concerned users here. The answer is pretty simple - it's a forum and we are here to discuss thing. If someone doesn't want to read our discussion about certain things, he should not post about it or even use a forum. Simple. February 13, 2026, 09:23:15 PM |

GPLama video High power after big ring sprint ahh. My spider didn't have this, but my sprint lower (1000vs1200) and on trainer. Will repeat sprint test February 18, 2026, 01:16:52 AM |

Re: Thinkrider PP5 power meter
Is it possible to perform zero offset calibration without unclipping?Proper calibration of modern power meters requires you to not put any extra weight on the pedal. Qq: you test in absolute, which is great, but as you can see, there are a lot of discussion about specific use case. Could you provide your feedback on that? For example I am relatively new to the sport, I have a Magene p515, I don’t think I ever hit 800W, could that be a suitable option. Or on a bike dedicated to zone 2 effort?It would be plausible only if we were sure anything above exactly 800W triggers the drift, but it could be lower than that. Regardless, it is very easy to get 800W for few spins if you are above 70kg even untrained or not intentional of hitting high power. In that case you may have already drifted away from the calibrated values. Tracking every high torque power spike and recalibrating each time after that is simply not practical. You may probably use it for indoor training in ERG mode but in this case you already have more accurate measurement from the trainer. My suggestion to everyone who already own this PM is to check for the drift yourself - maybe Shane has faulty unit (which is unlikely). I personally wouldn't buy it. February 18, 2026, 06:11:25 AM |

Re: Thinkrider PP5 power meter
Whenever he tests one there is always this talk that he may have received a dud one.. When he tested elilee they said the same thing.. They sent two EK01 (one alloy spider, one carbon) that both had the same issue. They published a press release proclaiming the issue resolved, follow up testing showed it wasn't. The bigger issue I see with the EK01 is that their World Tour team are getting different non-commercial versions of these meters. Why? February 18, 2026, 04:20:28 PM |

Re: Thinkrider PP5 power meter
[.]] Even if a top brand like Shimano have some problems... I can deal with a cheap chinese one inaccuracyWhat's the logic here exactly? If one company cannot make a good power meter I'll use an inferior one on purpose instead of getting one that works. You people baffle me. February 20, 2026, 04:10:07 AM |

What's the logic here exactly? Money... If a product price is low enough, people will buy it, regardless if it works as intended... February 20, 2026, 05:59:40 AM |

Re: ThinkRider PP5 power meter, worth to try?
I was initially tempted to get the ThinkRider PP5 because it’s cheap, but while doing my research, I came across Shane Miller’s review（https://www.youtube.com/watch?v=y0CZEbVhC5w）. His real-world testing was pretty straightforward: the power meter may be low-cost, but its accuracy and consistency are not reliable, and the data fluctuates a lot at higher power levels. For me, the core of a power meter is whether the data is accurate or not. If it’s not, then no matter how cheap it is, it's just money wasted. Honestly, even with a tight budget, don’t compromise on the power meter. Accurate and stable data is just too important. My recommendation is to read the forum first before starting a new pointless thread February 26, 2026, 10:54:48 AM |
