Is it really necessary to have a stockpile of spare parts and accessories for an eBike, or are manufacturers and local bike shops overemphasizing this need as a way to drive sales? Ive seen some people swear by carrying a comprehensive toolkit and spare parts with them on every ride, while others seem to get by just fine without. Whats the real cost-benefit analysis of having access to these parts, and are there any situations where not having them would be a major liability? Should we be pushing manufacturers to design eBikes with more standardized, easily-swappable components to make maintenance and repair more accessible to the average rider?
