We offer 2 years warranty on the engine and motherboard and 1 year warranty on the battery pack.
If the product is dead-on-arrival, we will cover the shipping costs for returning it to us. Tires and inner tubes are outside of the scope of the warranty. If you change the tire/tube, it will not void your warranty given that there was no damage done on the product during disassembly.
This warranty does not cover wear and tear, breakage or damage during use and misuse of the product such as exceeding the weight or speed limits of the product (check the individual model specifications). However, we can repair or replace faulty parts that fall outside of the warranty at an additional charge.
