Using this wheel set is easy. First, make sure your bike is compatible, especially if it's an ACE - X bike from 08/2020 - 09 - 2021 with a light switch. If you have another model, it should work too, but be aware that speed display might not function. When installing, follow basic bike wheel installation steps. For maintenance, keep the wheels clean. Wipe them down regularly to prevent dirt build - up. Check the spokes for tightness every few rides. If you notice any issues with the motor or the cassette, it's best to take it to a professional bike mechanic. And always use the appropriate controller for the best performance.
