A '''sissy bar''', also called a "sister bar" or "passenger backrest", is an addition to the rear of a [[Engineering:Bicycle|bicycle]] or [[Engineering:Motorcycle|motorcycle]] that allows the rider or passenger to recline against it while riding. Alternatively it can serve as an anchor point or support for mounting luggage or equipment that is not part of the bike. They can serve as one of the main mounts securing the rear fender to the motorcycle. Over the years the sissy bars have been a focal point of expression for the bike builder. Custom sissy bar designs can be simple or extravagant. They can be built for comfort, purpose, style or a combination of all three.<ref name="lowbrow">{{Cite web|url=https://www.lowbrowcustoms.com/blogs/events-features/a-new-way-to-think-about-sissy-bars-for-motorcycles|title = What is a Sissy Bar?

In the early 1960s some states initiated laws that mandated the use of a bar on the back of a street motorcycle for safety reasons. At the time bikers were not a group particularly concerned with safety, and started referring to the bars as "sissy" bars because they were not happy about having to comply with the new law. Some bikers began making excessively tall sissy bars as a form of protest, which later became part of the modern chopper look. A variety of materials were used to fabricate these custom sissy bar designs such as tubing, rod iron, plate metal, and even welded chain.<ref name="lowbrow" />

Sissy bars for cruiser-style motorcycles are usually affixed to the rear fender [[Engineering:Strut|strut]]s, and are typically made of chrome-plated steel with a foam padded seatback for comfort. Some elaborate custom examples can extend three feet or more.  A backrest for a [[Engineering:Touring motorcycle|touring motorcycle]] is often shorter and less elaborate and may be built into a top box.

==On bicycles==
Inspired by its motorcycle counterpart, a smaller version of the sissy bar was a common feature on 1960s- and 70s-era [[Engineering:Wheelie bike|wheelie bike]]s, such as the Schwinn Sting-Ray and the Raleigh Chopper.  This extended backrest, which attached to the rear of the bike's banana seat, gave a passenger something to lean back on and hold on to besides the rider doing the pedaling.
