Now I need tp find pants that wear better found some but they had reinforced knees and they rubbed my knees raw.
Yeah, it's just the first gen "Classic" drives that had the 1:1 until the current batch came along.
With the cargo bike on these hills, a lot of the riding is full-assist climbing or full-brake descending. It's a lot to put a chain through.
For the pant thing, maybe some separate knee guards would work well? I dunno, fit can be really tricky and a lot of mountain bike clothing has tough stitching on heavy-duty nylon so there can be a lot of sawing. Could also try wearing some thin roadie knee warmers underneath the reinforced stuff to give some relief from the cheese-grater effect.
