Levo Gen 2 Specialized batteries are only designed to last 4 to 6 years

Didn't know this, i just bought a turbo levo this year but, according to the chief product officer

"The bikes are built to last a lifetime, but the batteries typically run out of power after four and six years, said Chris Yu, chief product officer at Specialized. “Generally, the bikes will long outlast the packs for the typical user,” Yu told The Verge. “And so it’s always been in the back of our minds: what do we do about them?”"

Tesla’s co-founder is teaming up with Specialized to solve the problem of e-bike batteries

There is a tsunami of lithium-ion batteries on the horizon that will need recycling.

My understanding is that they are not designed to fail after 4 to 6 years. Rather, given current battery cell technology and the anticipated number of charge/discharge cycles per year, that it the expected life.

RebornRider has it. That said, lithium-ion battery pack life will vary significantly, esp. in a system like this without a lot of advanced electronic/thermal management (unlike, say, that of an electric car) depending on how you use it and recharge it.

I share this link often: How to Prolong Lithium-based Batteries - Battery University

You can see that by simply reducing the depth-of-discharge (DoD) 20%*, one can increase the the number of charge cycles by 60% to 100% (read: double). And then there is thermal management, which is a function of how much current you draw, what temperatures your eMTB is used/stored in, how you conduct your charging session (all-in-one-go to 100% the night before? piecemeal to ending-up at 80% on the morning of?), etc.

(* One might wonder how one would reduce the depth-of-discharge without adversely affecting the experience of a given ride. Easy: by using a bigger battery. Yeah, bigger batteries weigh more... and one might wonder why one would want to carry that extra capacity all the time if one's not going to need it for their average ride. But they forget what you gain with the extra capacity isn't just the ability to cover the occasional bigger ride... but rather the decreased DoD. A marginally bigger battery can net you a dramatic increase in battery lifetime.)

Had my 2018 Levo 3 years now and covered 12,000km. The 504wh battery has had 234 charge cycles in that time and the current health is 86% or 434wh. I estimate bout half its life it has been discharged below 20% and the other half below 50%.
End of the day, it’s still going well and only just short of a 460wh battery that was available in that model year.
I really don’t think the majority will ever keep their bike as long as I have or do as many kilometres. Batteries are now 700wh, so why even think about it. Just ride ya dam bike ?‍
