180mm Disc Brake Rotor 2 packs CYSKY Stainless Steel Bike Disc Brake Rotor 6 Bolts for Most Bicycle Road Bike Mountain Bike BMX MTB (Include 12 Screws, Black)

I was able to get about 2000 miles off the routers that came with my bike and these have been a perfect replacement for them. I have about 700 miles on them now and no issue whatsoever. They also seem to be more robust than my previous pair. For sure a great buy for an E bike (can handle the added load of the machine).
