This will not give the drive enough insurance because once the tail hits the ground there’s not much he/she can do besides wreck. By adding two sets of joints to the frame, we were able to allow the new tail slider to let the bike and rider down at a more controllable rate. As the tail slider first makes contact with the ground, the first set of joints absorb some of the impact energy. When the bike reaches a high enough angle with the ground, the second set of joints smooth out the transition of balancing on the back wheel. From the design that we conducted and our experiences of riding, we improved the slides on the existing products. We tried to assume all the possibility that the bike needed to be much safer for the rider and other drivers on the roads. The biggest improvement from the old design was adding the wheels to the rear. This gives the rider a safe surface to fall back on if needed, and almost act as training wheels for the whole bike. The wheels eliminate most of the friction between the ground and the part itself, and help absorb the force of impact with the ground. The rear of the tail slider consists of two rubber wheels with 2 ½” of surface area, spaced 2 ½” apart. They are equipped with a ball bearing center assembly to practically eliminate friction. Tail bars, 12 O’clock bars, provide a window of opportunity for the rider to correct their mistake and save themselves from injury. The existing tail bar systems are crude in design but gives the rider a slight advantage that they wouldn’t have otherwise. These tail bars can also impose greater risk of injury if they are misused. If the rider brings the front wheel off the ground too fast or too high, the tail bar will scrape the ground and the bike will be thrown off balance. Ingenuity 12-OClock-Bar ** Existing Systems Criteria The design requires some solid design drawing and material selections for the frame and wheels. The material selected for the frame of the new “tail slider” is 1144 carbon steel with about 6% carbon content, making for a medium strength alloy common in automotive applications. The density of this steel (7.84 g/cm^3) is much higher than other composite materials such as carbon fiber, but will withstand the impact of hitting the ground by bending rather than shattering like carbon fiber The double joint design acts as a safety net to slowly let the rider apply weight to the back wheels. The main problems we found in the old design were harsh contact with the ground, and excess friction from raw metal scraping against asphalt. We proceeded to fix these problems and have developed a new product that will help avoid the potential hazard of a high performance street bike sliding down the road uncontrollably. Sport bikes are one of the most popular and dangerous forms of transportation today. It takes years of riding to develop the skills it takes to perform stunts on a sport bike at a professional level, and even with those required skills there are many risks involved in riding. Aspiring stunt riders can easily be involved with wrecks high speeds and some incidents end in serious injury or even death, either because of the rider’s inexperience or unawareness of other vehicles. Stunt riders become more prone to injury as they go beyond the intended abilities of the machines them selves. To develop wheelie skills without fatal accidents an existing device is put in place to prevent over rotation. These are called “12 O'clock Bars”. Without this proper protection when training injury is more likely. Illustrated in the graph below is a study from the Insurance Institute for Highway Safety relating depicting that there are higher fatality rates in younger riders over the years. Young riders that go to stunt shows may be inspired, but don’t realize that they’re riding capabilities aren’t adequate to perform these stunts. Even though 12 O’clock bars currently exist there is room for advancement. Through proper engineering and assessment these safety devices can be improved so that they will be more desirable to use and are more apt to save lives or prevent injury. The design of a system for all bikes is nearly impossible due to the various configuration of the frames and cowlings from one model to another or manufacturer. The most pertinent constraint is the fact that specific considerations must be made per make and model of sport bike.
