Ok so I'm very new to motorized bike ownership. I recently purchased a nel luso beach cruiser used from fb marketplace (paid 150$, then purchased a used motorized american blades mountain bike for 135$). The bike first shredded the back tire while my hubby was riding it to work, so I quickly learned how to change that out and adjust it to not scrub the frame or the chain (which is what shredded it to begin with), hubby was riding the bike 23 miles a day back an forth to work, after a few weeks or so the back tire seized up while he was riding it. So he pedaled the rest of the way to work. After getting it back home, he now rides the mountain bike. After reading many forum posts and looking at many youtube how to vids, AND today FINALLY being able to compare the two bikes with the clutch gears cover plate off, finally figured out why tje back tire seized up, ABSOLUTELY NO GREASE whatsoever on the gears inside, which I'm pretty sure seized up the smaller gear which i will post a pic of, that will not turn AT ALL. When the clutch is engaged the bike moves smoothly. Disengaged, no movement. The large gear moves less than a 1/8 of an inch, the small gear moves NONE. I desperately need help to get this thing unstuck. Uploaded pic of the gear I'm talking about. Not sure of the proper names of the engine parts.
