Modify TBIS 4210-2:2017 as follows:

Sec. 4.6.1 Braking systems
There should be a warning before the end of the wear limit (pad, rim and rotor).
Sec. 4.9.7.1 Static brake-torque test

When tested by the method described in TBIS 4210-6:2017, 5.6.2, there shall be
no fractures or visible cracks in any part of the fork, and record the ratio between
weight and rigidity in the test result.
Sec. 4.10.4.1 General

Where quick-release axle devices are used they shall comply with 4.10.5. And
the quick-release devices nether loose nor fastening are not cause interference in
the running wheel assembly at bicycle complete assembled state.

Modify TBIS 4210-2:2018 as follows:

Sec. 4.8.7 Folding mechanism-special requirements

For the frames with folding mechanisms, the folding mechanisms should
conform to the requirements of Sec. 4.8.1~4.8.6; besides, it is necessary to
measure the opening force and the closing force of the folding mechanisms
before and after the test (if the opening force and the closing force are adjustable,

the opening force and the closing force should be adjusted to the maximal value);
the opening force and the closing force should not be lower than 90% before test,
and should not be stuck; in addition, the rotation shaft of the folding mechanisms
should not be loose because a gap appearing in the shaft.
