1. Remove the seat by lifting the front of the seat and pulling it back until it comes off the rear seat post.
2. Once the seat is removed, you will see a black cover on the right side of the bike. This cover is held in place by two screws.
3. Remove the two screws and lift the cover off the bike.
4. The battery will be located under the cover and held place with two 10mm nuts. Disconnect the battery cables by loosening these nuts.
