There’s so much to unpack here, and respectfully a lot of it is wide of the mark, or a bit misleading.
‘Rare minerals’ are also used in all sorts of chemical processing including the refining of petrol. These minerals are amongst the most abundant on earth, but until now there’s been no drive...
What are you doing to them?
I’ve been using lipos in my RC hobby since they became available, I’ve only lost one to a fire and that was when I nosed in the rc aircraft from 200ft that it was in.
Charging them with the appropriate quality charger and I’ve never had so much as one get hot.
My earlier Focus Jam2 is running a SRAM AXS GX rear derailleur, basically they hang off the standard hanger that your bike already has so will fit. You could probably just change the shifter and rear mech, if your bike already has 12 speed Shimano then you could keep the chain ring, chain and...
Pure guesswork, but don’t summer 2025 bikes launched get called the 2026 model anyway?
It’ll be out when it’s out, but interested to see which rumours turn out to be accurate! 😊
Probably just an area in which they need to be flexible, DJI design and make 100% of their drone products, e-bikes are not vertically integrated in that way.
I think that’s consistent with what I’ve been talking about, ie the battery pack is ‘oversize’ to ensure that the designed and advertised capacity can be delivered for the reasonable life of the product.
Perhaps what dealers can see with their diagnostic kit is degradation of the complete pack...
He says many things in the video, including ‘even if you do everything wrong, the battery will still last for a very very long time’ and also ‘if you need to charge to 100%, don’t worry about it’…
Electric car batteries are a rather different kettle of fish though, my current one at 100% SOC is...
I’m saying that the battery management is telling me that it has 100% of the capacity relative to when it was new.
A typical lithium-ion battery is usually rated for at least 500 cycles, so 170 is not really a lot in the grand scheme of things, so why shouldn’t I believe it?
To be clear, again, I was demonstrating that one of my own batteries in one of my own e-bikes used at my convenience rather than that of the battery is telling me that after 4 years, 170 charge cycles and 2200+ miles that it’s available capacity was 100%.
It even says that in the app...
Battery charge percentage and battery health percentage mean two different things, that’s why they’re both displayed in the specialized app.
Battery state of charge is not the same as available battery capacity, which is what is being referred to by battery health.
I have never said that 100% in the BMS means no degradation. Show me where?
The discussion, such as it is, is veering between straight chemical battery degradation and available battery capacity for the given application, which in this case is powering a motor to assist your pedalling. The two...
For goodness sake… 🤦♂️
It is 100% for the purposes of my ability to use the bike as it was designed. It has the same range visible to me as it always did, of course it will have degraded, but if Specialized are hiding that degradation from me in the way of a decent BMS, why do I care? It...
Whatever the reason, the point was that this is a 4 year old battery that has never had that 80% option, is a small one so has frequently been charged to 100% but 170 cycles and 2800+ miles in it’s still 100% healthy.
It’s just been used to suit me rather than the other way around.
The motor...
If you’re running the stock forks, then switching to a Domain or Lyrik etc will save you quite a bit and make the bike a bit more nimble.
The 500Wh Gen 3 S4 Alloy I have was 23.5kg with a Lyrik fork.
I’m 178cm, so both an S3 and S4 ‘fit’ me, but in hindsight I prefer a more playful and manoeuvrable bike for my riding and trails.
My new frame is S3 size, and more similar geometry and sizing wise to my Jam2.

Description Ok, so I’ve posted before about my love/hate relationship with my Gen 3 Turbo Levo Alloy, and ultimately I’ve decided that the fact...
A healthy quality battery will last for over 12 months before it would be anywhere near flat, so it wouldn’t need replacing.
Also, a new factory battery will still have its passivation layer from when it was manufactured, this doesn’t migrate away from the cathodes and anodes until it starts...
