  • Ensuring the vehicle maintains its power after long-term use. The vehicle is not affected by worn-out components.

  • Providing the user with a sense of safety and comfort while operating the vehicle.

  • Saving costs for unexpected, severe damage.

  • Ensuring the validity of the vehicle's warranty and also serving as a basis for determining quality if you have the need to buy/sell with others.

The cost of regular maintenance will depend on the wear and tear of the components on the bike. For components that wear out or become damaged due to usage, the customer will be responsible for the cost. For errors/damage arising from manufacturing defects, Dat Bike will provide warranty coverage for the customer.

  • Errors arising from Dat Bike: Dat Bike's warranty policy will be applied.
