Here's my list with some conflicting items: Rechargeable lights (USB for convenience) - 2 front, 2 back for redundancy. Extra light strips for arms / backpack as needed. Decent pump. Saddle bag with spare tube and tyre levers. Helmet Glasses with clear and tinted lenses (I use photochromic lenses) Waterproofs Winter gloves Overshoes Edit: This post is more about accessories than the bike itself.
