Every machine needs maintenance and repairs and an electric scooter is not an exception to this. Of course as compared to a gas powered scooter the amount of maintenance required for an electric scooter is much less, but needs care just like every vehicle.
Gas powered vehicles machines are complex systems with so many things to look after on the other hand an electric scooter is a very simple machine. A person with little knowledge of electrical circuits can repair it on his own without any need to look for a mechanic. But if knowledge of electrical circuits is not there, many options are available.
If you have an electrical scooter in need of repair the first thing you can do is take it to a standard mechanical workshop and ask for help. Since normal gas powered scooters also have electrical circuits in them, every mechanic will have at least some basic knowledge about circuits.
If they refuse to repair it you can simply ask the manufacturer of the electric scooter regarding any special workshops where such electric vehicles are repaired. Since selling electric scooters is a business for them it is strong possibility that they have special tie-ups with workshops around the country to service their scooters.
Depending upon the kind of repair your scooter may need a week or for minor repairs just a few hours. Sometimes it is just a matter of charging the battery (if you don’t charge it regularly) ad it’s ready to drive again.
However it is necessary to understand that “prevention is the best cure”. Regularly use your electric scooter and don’t forget to charge it regularly too. If you are way for a few days from your home, you can carry it with you or store in way that it is safe from moisture. Normally it is advisable to look for repair shops before you buy an electric scooter bur since these machines are not complex, they can be repaired easily without much expenses on your part.

This video shows the process of repairing this Schumacher SE-2158 battery charger. In this particular case, the charging capacity selector switch had an intermittent contact on the 12V/10A setting (probably the most used setting for this charger). The switch replacement was quite straight forward and went very well. I now have a capable battery charger for almost any occasion that only cost me $25 in repairs. It’s amazing that this thing was left on the side of the road. It’s got allot of life left in it. (1/18/2016)
Video showing how I managed to salvage a broken chicago electric automotive battery charger.
I fixed a Dell Laptop that refused to charge the battery and I was using a genuine Dell AC/DC Power adapter that had a broken signal cable. It took some careful adjustments to the DC jack in the back of the laptop. In addition there is a signal cable that easily gets severed over time in the end of the DC power cable. By making these two repairs, the laptop works perfectly, the power cord stays in firmly, and the battery charges without problem.
However, this works if it is a hardware problem. If your in Windows and the device driver refuses to acknowledge the charging state of your battery, then I recommend Nick’s solution here: https://www.youtube.com/watch?v=Lx62t6qZ34U
