@roezone@BrentToderian ITYM one of the few DIY ones. It's not "luck" that I chose to get battery motor & frame separately or can replace any one of them. I remain unimpressed with bosch / shimano #eBikes, but I can see why bike shops won't deal outside of that supported yet locked-in scheme, they're not electrical technicians and most don't want to be. Meanwhile manufacturers want to be exempt from #rightToRepair, and there's still very little open source controller specs & software options.
