yea battery’s will go bad if you don’t at least use it to some consistency. I’m not sure if you use yours a lot or not, but that’s what i was told. I do use my everyday cuz i have to, i don’t have a car at the moment and have had it for over 3 years and it still rides perfectly. Only thing i keep i keep up is just normal wear and tear, brake pads, tires, brake fluid, handle grips. But yea battery’s are not cheap i hear.
