Really the only reason I dont ride much in the winter, is because i just dont enjoy riding in wind and rain. Cycling has to be enjoyable for me to do it, and as i'm only a leisure cyclist i can pick and choose as and when.
More of an issue to me, is high summer heat, even more so now with the heatwaves that are becoming more frequent every summer now. This isn't just not enjoyable for me, but seriously affects certain health issues i have.
I sometimes wonder why i persevere with unassisted bikes and maybe should just stick to ebikes. But its hard to quit them completely.
