I just passed 4000km on my bike without replacing or repairing a single component of the electrics. Every time I’ve thought I had a problem it has turned out to be the bike itself, not the electrics. I use the bike for my regular commute and I live in the subtropics, so it has ridden through cyclones and thunderstorms as well as hot weather without missing a beat. It’s just as responsive as it was when I bought it.
