![]() Two different wheel sizes complicate stocking replacement tires, tubes, and rims. ![]() Inferior roll over behavior for rocks and roots.A stronger and at the same time lighter rear wheel.More space for increased tire clearance in the tightly spaced bottom bracket area.An effect which is often cited as the reason for a more nimble ride feel. Due to the smaller diameter, a smaller rear wheel has lower gyroscopic forces.Watch out for MX bikes, as this is the term that bicycle companies often use to market their mullet bikes. As a result, we see many companies starting to sell bikes with mixed-sized wheels. Naturally, that sparked the interest of the mountain bike media as well as the consumers. Since the UCI allowed mixed wheel sizes for the 2019 race season, many downhill athletes chose to run mullet setups in their competitions. The basic idea is to combine the good roll-over behavior and gyroscopic stability of twenty-nine-inch wheels in the front (where it matters most) with the nimbleness of a 27.5" wheels. It describes the combination of a large front wheel with a smaller rear wheel, typically 29" up front and 27.5" on the rear. Mullet bikes are a trending subject in the enduro and downhill mountain bike world.

ANSYS, like SolidWorks, was an important tool in verifying design assumptions and concepts. The SolidWorks models where then transported to a computational simulation program, ANSYS. It was decided this was a vitally important ability, as future modifications will be needed when less conservative loading cases are discovered and then applied. This is an extremely powerful program that allows the user to not only produce a three-dimensional component but also allow future modifications to be made to the component to change its dimensions. SolidWorks was the tool used to generate the components created in the design phase. After several redesigns a final model was able to be created. Working closely with the rear drive train, cockpit and upright teams, a design was conceived and developed. Contrary to the current push-rod suspension on the Gen 1 car, the pull-rods allow the centre of gravity to be lowered, which is ideal. After in-depth research it was decided that a pull-rod suspension system would be the most effective assembly for the Gen 2 car. This paper details the design and simulation of the James Cook University Motorsports 2nd generation vehicle for the Formula Society of Automotive Engineers competition. The suspension assembly of a vehicle is a vital component in its ability to function safely and effectively.
