One of my friend's younger siblings recently got a Razor Pocket Mod (the mini moped) for Christmas. After getting a chance to ride it, despite being too big for it, I began looking into purchasing one. However, I quickly realized how crappy of a moped it is. What I was wondering is how difficult it would be to remove the current parts in one and essentially make it a micro moped ebike sort of thing? I'm looking for ~20mph and ~5-10 mile distance.
