One thing missing from the back of my bike was a reflector. It likely had a rectangular one under the seat when it was new- that to me is not really very much in keeping with the ethos of the bike so I had a rummage and found this on Amazon:
A 1 1/4″ round reflector, metal backed, made in New Jersey. I made up a small metal bracket, painted it black and attached it below the light on the rear fender.
Ordered also a small module housing a couple switches to operate the lights and ignition- the push-button on the handlebar that currently kills the engine is going to be for a horn of some description, something a little louder than a bell.
Annoyingly, it arrived broken. I glued it up and now it’s better. Next up, dismantle, rub down and paint up handlebars… then refit all the parts.
