We recommend that you clean your Evolve from dust and dirt after each use. Especially your bearings as these play an important part in providing you with a smooth and efficient ride. Also, if you do not maintain your bearings it might reduce the performance of your battery or lead to bearing failure. We also recommend that you frequently clean and keep an eye on your motor or belt drive - to see if there is any damage. You can easily maintain your electric longboard by using a damp or dry cloth to swipe it down. Also make sure that all nuts and screws are tight!
