My big complaint with Swytchbike is the lack of backwards compatability. In short, you buy a Swytchbike today, but 3 years from now, you can't get parts or even worse, their entire model format has changed. For example, the original batteries from Swytchbike, sold several years ago, are no longer supported. So what am I supposed to do with them? I can't buy an extra battery - they're no longer making them. In fact, the only course of action is to replace the entire power module (battery and battery mount on the handlebar). This is not very consumer friendly. I don't expect my e-bike to be outdated within a year or two by its own manufacturer. But mine was. The hardware Swytchbike makes is unique to Swytchbike. When it's outdated, it becomes trash. Very disappointing.
