These bikes are great in so many ways, but the way the headlight's top screw and the tail light screws in leave them VERY susceptible to coming loose since they're threaded into cheap plastic. My machinist friend made an aluminum replacement for the headlight screw in problem, and my motorcycle tech friend solved the tail light issue. My machinist friend has a few of the headlight pieces leftover from when he made mine and is selling them for 25 each, shipped within the US. I'm also happy to share how we/he fixed the tail light. You use a dremel and smooth out the surface. You apply epoxy and then 2 elevator bolts. Let dry for 24 hours and then simply bolt back in using the original rubber grommets in their same places.
