I have 9 Motrons, 3 of which are that color green, and I like that color the best as well. I also have a Pryer rear end and plan on making a trike as well this summer. I could use any help with the project as possible.
The bike I plan on using is a red model that was primed by one of the previous owners and now consists of 4 different colors; on the fork, rear fender, gas tank, and frame. I'm thinking of a hot pink color for several reasons. First, maybe the color will interest my youngest daughter in mopeds. Second, if I can't attract attention on a trike moped, I sure as hell ought to attract attention on a hot pink trike moped!
Good luck with the project and keep us informed. (edited)
