Main points before buying

* These controllers are only fit for ZERO/GRACE series and Speedual series which are made by our factory. The corresponding scooters made by our factory can equip them too, such as Quick Volt/Eco Speed/Ecobee/Country man/Turbowheel/Apollo/Go green/Muvter/Techlife, please check your scooter's original controller, measure the size and watch parameters on the label, compare with our description photos, if they are same, so they are compatible.

* Please choose the right model based on your scooter's model, if your scooter is 48V, you must choose a 48V controller, the others are incompatible.

* If your scooter is not made by us, I strongly suggest you don't purchase them, I don't know anything about your scooter and I can't give you any useful information, obviously I don't know what would happen when you replace them. Of course I won't assume liabilities in this situation.
*We don't provide corresponding screws/bolts/adapters and installing tools.

* We don't provide corresponding screws/bolts/adapters and installing tools.

* Installation requires hands-on ability and strong strength, it's not easy, please consider seriously before purchasing, if you don't know how to install it, please ask for a mechanic in your local store.

* Make sure all the screws and quick releases are tightened before your riding.

* The price do not include customs and taxes. There is a certain probability that the goods will be checked by the customs, if your package is checked, you need to pay the customs by youself. I don't know the specific customs tariff standard. You need to ask about the customs agency of your country.
