The Heavy Rider is one of the Hard-Boiled Heavies and the tenth major boss fought in Sonic Mania when playing as Sonic, Tails, or both characters together. She is encountered at the end of Lava Reef Zone Act 2, along with her trusty Moto Bug steed, Jimmy.
Heavy Rider will continuously ride back and forth on Jimmy, swinging her mace around. Because of the mace and her high speed, she is a tricky foe to land hits on. If the player is about to collide with Jimmy, the Moto Bug will jump over them. Eventually, Rider will decide to perform one of two stunts:
- She may choose to drive up onto the ramps and make a daredevil jump over two flamethrowers that will spit fire all over the arena. This will get the crowd cheering and cause confetti to rain down on the arena. During this attack, the player must stay out of the center of the arena unless they have a Fire Shield.
- She may also choose to ride off the left or right sides of the arena, rev up some speed, and zoom across to the other side with the mace held out in front of Jimmy. If she decides to do this right after the above stunt, she will leave a flaming trail that will hurt the player.
After eight hits, she will be knocked off her steed, ending the boss fight and allowing the Capsule to fly in.
- Jimmy the Moto Bug is a tribute to Sonic Retro community member Polygon Jim, who passed away in a car accident in 2013. He was famous for creating Motobug the Badnik in Sonic 1.
- For whatever reason, the Heavy Rider releases an animal when defeated. None of the other Hard-Boiled Heavies have this behaviour.
