1B7070 Air Spring Used In Bicycle Seat
The air spring under the bicycle seat cushion mainly acts as a
shock absorber.
When the bicycle passes through the bumpy road, it can buffer the
vibration of the bumpy road, avoid sudden and strong vibrations
that cause safety hazards to riding, and make riding safer and more
comfortable.
The design with an air spring under the seat cushion is usually
used on bicycles with leisure and transportation functions, which
can improve the comfort and safety of riding.
