Note: At the moment only the blue ones have tools to give away!! ◇ BREATHABLE The hollow design in the middle of our bike seat not only reduces the weight but makes it more breathable. ◇ ANTI-SHOCK The spherical shock absorber under the bike saddle makes riding more stable and reduces the pain caused by vibration. ◇ REFLECTIVE Extended reflective strip better reminds vehicles and passers-by and improves safety when riding at night. Insert the clamp and the card between the seat arches. Pass the screw rod through the clamp and the small hole. Pass the outer card through the screw rod. Fix the distance to the hole with screws. Install the saddle and fix it on the bike seat tube. Adjust the position and tighten the screws.
