4.5Safety height mark
4.5.1Safety height mark of the stem
The stem can be properly adjusted depending on personal riding habit, but the safety mark cannot be exposed; It may
cause serious injury in case of improper operation.
Adjustment method:
1.
Loosen the screw in the middle of the stem
2.
Move the stem to a certain height, and do not make the safety mark exposed.
3.
Fasten the screw.
4.5.2Saddle position
When you sit on the saddle to tread on the pedal flatly by heel, when the pedal is at the lowest position, legs slightly
stretch, and at this time it is the most suitable height; if the rider can tread on the pedal only by toes or legs cannot stretch
slightly, fatigue and sports injury will be caused, so there is a careful need for adjustment of the height of the saddle post.
The saddle post has a max mark line, that is safety height mark which cannot be exposed. In case of improper use,
serious injury may be caused.
