Some generic Shimano disk brake, I think BR-something. Got BOS1 brake pads on it. I don't commute on it, but definitely ride at least a few hundred kilometers on it a year. They aren't particularly performant, you should always be able to lock up hydraulics with a single finger if they are adjusted correctly imo. Even my mechanical avid BB7 disks I could lock up with a finger when my brake cables were newer.

I've ridden my (heavy!) e-bike for a few thousand miles, and although I've replaced tubes and tires, I'm still on the original disc pads. I don't think they're anything special, just middle of the road cable actuated stuff. Do pads usually wear faster? Honest question.

Depends on the riding conditions. The pads on my road bike lasted about 10,000km. In 12,000km my mountain bike has needed 6 sets of pads and 1 set of rotors.

Mine usually last 1000 km. What brand are yours?

The stock pads the came with the Rad Rover. Tektros, I think. https://www.radpowerbikes.com/collections/brake-pads
