This, and the propensity for manufacturers to hyperfixate on trying to make everything proprietary, is why I will never buy a prebuilt e-bike. My bike is a converted regular bike, and if any component fails I can just rip it off and replace it with any of a variety of readily available yum-cha components. The prices a lot of manufacturers are asking for these pieces of shit are astronomical, too. If you’re not afraid to run a wire or two, you can build a more performant bike with bigger battery capacity for half the price or less.
