3.5 Professional store maintenance
It is recommended to go to a professional store for maintenance 2-3 times a quarter,
or after every 1,000 km of riding. The following items should be checked during such
maintenance:
1) Performance of the hydraulic brakes.
2) The tightness of screws, especially those between the discs and bottom brackets,
in key parts.
3) The wear degree of the front fork parts.
4) The wear degree of the front hub bearings.
5) The wear degree of the pedal pivots.
6) The professional store’s technicians should lubricate the internal pivots to ensure
the smoothness of pivots in front fork parts, front hub bearings, bottom bracket,
and other parts.
7) The wear degree of the tires.
8) The fastening performance of the bottom bracket torque sensor, battery, controller,
motor, odometer, and other electronic control parts.
