We recommend having a tire installed on your wheel. While not strictly necessary for the operation of Fliiiight, the extra inertia provided by a tire has a significant effect on road feel. Be sure to use a kevlar beaded folding tire. They're the most common type of tire, and are sold folded up, like in the image below.
Speed up! Using a higher, faster gear improves your road feel while increasing the maximum resistance and power your trainer can achieve. Note that you should always use your top gear in ERG mode.
Make sure the height of the resistance unit is aligned for your wheel.
Open the Chrome troubleshooting app and set the motion limit in a couple steps at a time. Note that while adjusting this setting can increase Fliiiight's maximum resistance, and increase the strength of virtual inertia, it will also increase the likelihood of wheel-magnet contact. How far you are able to customize this setting depends on your individual wheel. We recommend trying other troubleshooting steps first.
