I thought this would be easy. I have a Radrunner 2 ebike. Easy question: What brake pads do I need? Semi metallic, organic? What brand? Are Tektro 10.11 all the same? I saw Tektro 10.11 organic but the add said it was for hydraulic brakes but I have cable brakes. Will these work? Lots of questions but maybe only one answer. Thanks for the help!!!!
