Fire roads are great for nightriding, not very technical, and a larger margin for error. I only ride singletrack at night that I am very familiar with, and I would avoid anything too technical. I look forward to riding with a group at night, as I have only ridden solo or with one other bike. The more people, the better chance they’ll find my body.
The first to find the body should get the bike. 😀
Part of it lies in the intensity of lighting, whether it be a high end light, or multiple light sources. I have a two beam light on the bars, and a single light on the helmet. Works great, and lets me see what is lurking trailside while still keeping the track in front of me lit. I have yet to see the trail lined with bikini clad models out on a night run…..one day.
