Had my Nudie jeans for about 5 year wearing them probably 4 days a week averaged over the whole time. Indeed the frequent cycling killed them, but it took quite a while. Now I'm figuring out when to bring them to their free repair service to see if I can get a prolonged live for them.

Disclaimer: cycled probably only 15 minutes a day with them averaged over the whole time, but really hard to say, so your millage might vary
