id totally buy a set of those off you if you made them. i dont have any nerfs or heelguards on my bike because most nerfs are a little larger than i feel necessary? very nice design though! and i like how the center mounts for them go up to that bracket on the frame. definitely very nice design, you should totally reconsider making/selling those, you've got skills!
(im mostly jealous because i went to school for metalworking and fabrication, and i have none of the tools available that id need to make that kind of stuff, just the knowledge.)
i agree that most nerfs are way to big, thats why i downsized mine, kinda a low profile look lol, but there is a couple things i gotta do yet (the right side bracket to the motor mount) now that i have a good design and pattern, mabe i could throw a couple sets together
