I'm talking about replacing the battery as a whole, currently there are many form factors and you can't be sure you'll be able to get a new battery when the performance of the original one starts to degrade. If manufacturers would be forced to make it replaceable for X years at reasonable cost, either by providing replacements or by adopting an industry standard, that would fulfill the "right to repair" IMO. You then want to extend that to the other main parts like the motor or the controllers, so you're not left with a piece of junk when one component fails. Just like for normal bikes.
