I ride a single speed with only one brake, and I don’t wear a helmet. I’ve ridden this bike at night, wearing all black and while wearing earbuds in both ears. But I do have a 3k lumen front light and a 400 lumen rear, so maybe it’s a wash? I suppose when I’m flattened into the Georgia blacktop by a driver that ‘didn’t see me’ as they were running me over in the far right side of the slow lane, going 20+ mph over the speed limit, I’ll know for a second or two wether I was always being unsafe.
