It actually appears to be per bike per 100km. I find that quite surprising given it's half the number of tyres, there's substantially less initial volume per tyre than a car's and, as you say, there's a lot less weight on them.
Given their focus on MTBs, I wonder if it's related to the type of terrain being ridden (higher incidence of gravel/sharp rocks than your average road) or different tyre compounds between the two vehicle types.
I would bet on different rubber being the culprit. My downhill and trail tires are super soft in order to grab the rocks and roots better. They wear out quicker than road tires because of this. Still takes a few years in with me riding every day but it’s noticeably faster than the roadies.
The problem is that it lasts the lifetime of the bike
@Fingolfinz @anindefinitearticle and only replaces the tubes, it still needs to be retread at some interval. So 'lasts the life of the bike' is a bit misleading....?
(Just going by the linked article)
Thank you for the clarification, I’m definitely not qualified to make any claims on it
I guess it went over your head. I’m saying that a company won’t make it because capitalism rules everything so since this is something that would be helpful for the consumer, it’s bad for capitalism.
Reduces waste and profit, that is a no-no.
Think of the poor shareholders!
The Germans, of course.
Oh wow thanks that is super interesting!
I have been wondering if you could do something like that with carbon fiber (using carbon fiber as springs) after once seeing a bicycle wheel with spokes that was made using carbon fiber wrapping. Which is a process that can be / has to be automated. If you could create the entire wheel including the tire through carbon fiber wrapping it could become really cheap and worth the downsides. This could be done by a machine that isn't much more complex than a 3D printer, plus a special 3D printed mandrel to build this tire on. Basically they just seem to be large loops the size of the tire that provide the springiness plus a mesh that holds it together with a rubber tread on top.
PS: Not sure if that "superelastic shape memory alloy" is fundamentally different from normal springs or if that is just marketing speak, or the need to function without maintenance or replacement in space.
PPS: Apparently it is vastly different from my idea.
