I love riding at night but I'm probably not going to do it until it stays warm at night, currently it still drops to 0 overnight. I run 3 rear lights and 2 front lights, so visibility to other road users isn't an issue. Of course, my night rides are largely for relaxing, cruising at a comfortable speed with no pathway traffic is really nice. If I wanted to mash I'd take my mtb out instead, same amount of effort but slower speeds and less swearing when I do hit a pothole.

I can remember every crack/bump/hole on the pathway so that isn't an issue. I do have an issue with off leash dogs running across the pathway like a deer would across a road.
