Some people might argue but I don't think Rad Power Bikes fall into the junk bikes category at all. But tangentially, one of my peeves about them is that they go to a good bit of effort to make people think their parts are proprietary even though in my not so limited experience they are not. I think, for example, if they were out of brake pads they'd want you to wait 3 months for them to get some in rather than tell you you can get some on Amazon, that will work at least as well and be delivered tomorrow or the next day. You just have to know something about what you're doing. Maybe that's the way it is with most mike manufacturers, but I don't think they do themselves any favors.
