In order to ensure your driving safety, I hope you do a good job before the inspection:
1. Is fetal pressure normal?
2. The front and rear wheels are locked, the wheel fastening nut torque is not less than 19.6Nm, the rear wheel nut tightening torque is not less than 30Nm.
3. Put the horizontal, the tightening torque of the nut is not less than 19.6Nm, the vertical pipe insertion depth is not less than the vertical pipe diameter 2.5 times times (insertion depth must not reveal the riser of the secure thread).
4. Saddle, saddle tube fastening nut torque is not less than 19.6Nm, the saddle tube insertion depth is not less than 2.5 times times the diameter of the saddle tube (insertion depth must not reveal the saddle pipe thread).
5. Chain tightening should be adapted to the chain free sag and tension between the distance between 5-10mm.
6. Brake debugging should be reliable, flexible reset, snow and rain should increase the braking distance.
7. Where the folding function of the vehicle, the fast-breaking device must be locked before riding!
