Why wouldn't you? The PM always "knows" which crank arm is up or down. So as long as you're not pulling on the pedals - which you really shouldn't do since it's inefficient - it always knows which side is applying how much power.

For me the readings are accurate. Usually 50/50 with an occasional up to +/-2 spread which seems normal.

No it's actually a lot more complicated than that and it's also a reason why other single sided PM brands/models don't offer L/R balance. The PM only knows if one side is putting power or not, that's it. To conclude that the other side is always putting exactly the same power skews the L/R stats. If you buy the assioma UNO (which is pretty much the golden standard for PM accuracy) you'll notice they don't provide L/R balance for that reason, because it's not possible to get accurate data. That's also why in the assioma app you can specify a L/R power balance if you know you're always outputting 45/55 for instance. This way the uno won't simply *double* your power but will use this ratio.

Think about it this way, with your logic you could be doing one-legged workout (where you only have one leg clipped in) and the single side power meter would think you're applying power on the other side when you don't even have a foot clipped on the other side. Single side powermeter will never be accurate for L/R balance because it can only tell if one side is putting power or not.

I've had assioma duos. During high intensity workouts/sprints it's very common to get an imbalance on the power because people tend to have a stronger leg/side.

I'd get a used bolt v1 versus a probably very unrefined chinese bike computer. Or if you really want something new I'd consider Bryton.

That is the current version of the app, looks exactly the same but it connects to my L508 without that message.

I would contact Magene support.

There was rumour of two different versions of the L508, one built just for the Chinese market and the other for the International market. If you bought your L508 from AliExpress you might of got the Chinese version.

I did buy my from the "offical" Magene store on AliExpress, but that was 18 months ago.

Thank you, I did try contacting them via email and even their FB page but no answers so far after a week... I'm considering asking for an aliexpress refund at this point...

I did download the chinese app (wasn't easy for me) and it does connect, but then without any translation the app is completely unusable for me sadly...

Just received my light, I unfortunately cannot connect to it with the Magene Utility app, how do I update the firmware then?

Anybody else with this issue?

"This device is not compatible with the current app. Please use the corresponding app."

My app version is v1.7.1

I installed the old design on 5 bikes, and i cracked one non drive side arm at 6 or 7nm. Racework is largely useless to deal with. They made so many mistakes in my order with them that i can't remember the exact count. Beyond the cranks, i bought 12s chains from them, they sent me 11s, the bar tape they sold me is the absolute worst i've ever used, and more. They refused to warranty anything, including the crank arm even though it was low torque (they dont tell you what torque to use, btw), but i managed to buy a replacement one for cheap enough - abnormal, but at least i still have 5 cranksets to use and not 4, for now anyway -.
We've put around 5k km on all these cranksets so far, i'd say. to avoid cracking more crank arms, i'm using 5nm and an obscene amount of threadlock. It's been working.
Either way they updated the non drive side design.
I wouldn't recommend them, goes without saying, but to be fair, i'm happy with the cranksets as long as it's not broken - kind of like i'm happy with my ltwoo er9 when it's not broken, the problem being that out of 5, 2 broke for no reason -, and their 3d printed saddles are nice too.

Wait so you had TWO failures with the er9 groupset and you still went ahead and got five? Or am I not reading this correctly.

"Happy as long as it's not broken" is not good enough, any failure during a 100+km ride is something that will ruin your day, and something that very rarely happens with groupsets from the big three.

Yes I don't think expecting perfection from a radar is reasonable, you should always be on guard all the time and the radar is just something extra that helps.

Thanks for the recent information, this is a bit reassuring, as firmware issues that can be fixed via software is better than having say a bad sensor that just would never work no matter how much code you throw at it.

How's the magene in group rides? Does it go crazy?

Oh they usually shift well enough, but with the increased tension of a clutch on a GRX derailleur I've had mixed results, whereas a cheap 105 cassette still shifts perfectly well on the same derailleur and with or without clutch. It can't be the derailleur when this variable is consistent between the two cassettes. Also I've noticed that in salty winter rides in Canada they tend to rust a lot quicker than Shimano cassettes. For dry weather they might be alright but anything wet/muddy they'll wear down very quickly.
