Thinking about it, there's a definite gap in the market for a cheap set of lights that could be permanently attached to a bicycle. Maybe something that uses a really hefty plastic zip tie or a crimp-on metal fixture?
This is where the concept of Reelights (remember them?) was spot on - they were permenantly attached, permenantly on, and completely vandalproof. But the stupidity of the magnet mounting on the spokes and the finikityness of the distance between said magnet and light was its letdown.
Sturmey-Archer Dynohubs anyone?
My Gazelle came with a Sturmey Archer dynohub for the front light (no standlight unfortunately, so I still need another light as I have a slightly dicey right turn on my commute).
To get the next model up with a dynamo back light was a stupidly big jump in price for some reason, so I fitted a Reelight to the back. Unfortunately the bit with the coil in was prone to getting bashed at work or banged out of alignment when I clattered over a pothole, no matter how tight I screwed it on, and one day when I was trying to adjust it yet again because it had stopped working, it came apart in my hands like cheese, including the wiring inside snapping. I only had it a month in the end. Rob looked at it as I swore copiously, and said ‘Only someone like Kim would be able to fix that’
(I don’t really want it fixed, it’s too fiddly a design IMO and in hindsight it’s probably easier just to charge the batteries for standard lights every few weeks)
The Gazelle does have a fixed rear light on its mudguard, which opens for battery changes with a screwdriver, but it’s a bit low down.
