Renae P.Renae P.: I finally got smart and replaced the cassette myself instead of taking it to a shop. It works fine. So far over 75 miles on it with no problems.

EricB: This was the factory cassette on a Quiet Kat Warrior hunting e-bike.
I had allowed my old chain to stretch WAY too much and the new chain was skipping on my lower gears after I replaced it. I decided to replace the cassette and chainring. Replacing the cassette was incredibly easy (plenty of how-to videos online). I bought the $10 Park Tool Shimano cassette tool, but I did manage to actually remove the old cassette with the "needle nose pliers method" that I found online before the tool arrived. I also did not have a chain whip? tool and simply used the old chain clamped with vice grips to keep the cassette from spinning.
A quick overview of the needle nose method:
1. Remove the rear wheel and lay flat on the floor with the cassette on top.
2. Using a chain whip, pipe wrench, large channel locks, etc..., prevent the hub from spinning.
3. Insert small needle nose pliers into the hub... pull out on the handle to spread the needle nose part as wide as possible inside the hub. Try to get the needle nose into 2 of the slots that are in the center, across from each other.
4. While applying pressure to spread the tips of the needle nose, rotate the needle nose...
