There seem to be loads of ninja student bikes this year.
For my sins I live just off the QBC, and when I venture on to it of an evening, there's usually a totally unlit bicycle with a darkly clad rider coming down the hill from KB. It's difficult to see them until they're very close to me.
I started noticing the prevalence of unlit bikes a few weeks before the clock change. I don't remember seeing nearly so many unlit bikes in previous years. It almost seems like it's becoming the majority/default thing to do.
