it damages the gearbox and chain Especially on electric bikes there's a shift towards 'integrated' gearing (either traditional in the back wheel or the new-ish Pinion systems), plus belt drive, which shouldn't have any problem with weather. That plus all bearings being properly sealed these days should make this a whole lot better than it used to. Still using the word 'should' because I don't have any experience myself apart from just riding through rain; I just cannot get over leaving any of my bikes outside, having been raised with strict 'no metal outside' policies :)
