We offer a 30 day guarantee on all gas scooters, electric scooters, mini chopper, gas skateboard, go karts, and scooter parts. Meaning the scooter is guaranteed to work for 30 days. After that you have to pay for any repairs or parts that are needed. If you receive a scooter that has a problem right out of the box we will send you the parts that are needed to fix your scooter. This doesn't happen often but it does happen on occasion. You can contact ScooterX directly for your warranty order. You must provide all of your original purchase information to them in order to get warranty help. ScooterX's support number is 702-889-1741 ex 2
