I love how bats follow me, using my bug-packed beams as a free lunch. I love riding after the pubs and clubs have closed, when the streets are deserted. I love the circus of lights. I love the silent whirr of wheels and stars.
The downside? Nighttime grinds up unlit hills take forever. And you have to remember to charge your lights. But that's about it. With some big lights, you own the night.
