Saddle angle: In order to avoid leaning forward when riding, it is appropriate for the front end of the saddle to lean
upward, the front and rear position can be appropriately adjusted based on individual height.
Minimum height of the saddle: move the quick release handle to the OPEN position, then put the saddle post to the
lowest place, and when the saddle post cannot enter into the saddle tube of the frame, it is the minimum height of the seat.
Maximum height of the saddle: move the quick release handle to the OPEN position, then lift the saddle post to the top
but the safety line is not exposed, it is the maximum height of the saddle.
Measuring method: place the bike perpendicular to the ground, and the distance from the highest part of the curved
surface of the saddle vertical to the ground is the height of the saddle.
4.6Braking system
The braking system is an accessory necessary for each bike and is the key to traffic safety; before driving, you must
understand your braking system, and do a good job in the inspection and adjustment work.
The general idea is that upon hard braking, the bike will surely stop in a short distance, but that is wrong. Upon hard
braking, when the wheels are suddenly jammed by the brake rubber, the bike will glide horizontally, and it not only is
dangerous but the braking distance will be lengthened. Therefore, the concept should be established is that the braking
system is only used to adjust the speed of the bike.
The braking system typically includes a brake handle, brake (disc brake, V brake, and many other types of brakes) and
brake cable.
The structure of the brake handle is as shown, the left brake handle controls the front brake and the right brake
handle controls the rear brake.
