Legality of home-built electric bike?
I live in northern New Jersey. My summer project is to build an electric bike/motorcycle. I plan on using a regular beach cruiser pedal bike, removing the pedals and mechanism, and powering it with an electric motor. I'm estimating it will go anywhere from 20-25 mph. I know the laws about mopeds and motorcycles, but what would this fall under, since it will be custom and home built?
I'm using Radioactive_Legos' Flat Tracker as a reference https://www.instructables.com/id/48V-Electric-Flat-Tracker/
