Maintaining your TranceBoard is very simple. None of the electrical or mechanical parts need to be serviced. Just routinely checking that screws and nuts are tight, bearings are clean and rolling, rotating your wheels and keeping your electric skateboard clean. The limit we suggest is 120 to 130kgs. Over this weight the board will loose some torque only noticeable on hills. But still, you can even drive two people on the TranceBoard, one sitting in front, the other one standing at the back of the person with the remote controller in hand. But be aware, you can drive very fast, even with two people.
