How to Assemble a Bike Seat

How to Assemble a Bike Seat
Making sure your seat is properly assembled on your bike will ensure two things: 1) that the seat is safely attached, and won't suddenly slip as your riding the bike, and 2) that the seat is comfortable. More common than loose seats, poorly adjusted seats are the bane of many a cyclist. A seat that is uneven or positioned too far forward or back can cause discomfort or pain in the groin, arms and lower back. Assembling you seat properly at the outset will help eliminate these problems.


Difficulty: Easy


Things You’ll Need:
  • 5 mm Allen wrench
  • Plumb line
  • Level
Step 1
Loosen the bolt(s) holding the seatpost saddle clamp in place. The seatpost is part of your bicycle frame. The seat will attach to this post. There is clamp, comprised of two plates (an upper and a lower) at the very top of the seatpost. A bolt or two holds the clamp in place. The bolts will require a 5 mm Allen wrench in order to loosen.
Step 2
Remove the upper clamp plate from the seatpost.
Step 3
Place the seat rails, located on the bottom of your seat, into the grooves on the lower clamp plate. Position the seat so that the seatpost bisects the seat at its center.
Step 4
Hold the two plates together with one hand and re-tighten the clamp bolts. Keep your 5 mm Allen wrench handy, as you'll need to loosen the bolts again to allow for seat adjustment.


Step 1
Sit on the bike with both feet on the pedals. A friend will need to hold you up while you're sitting on the bike.
Step 2
Backpedal until your feet are at the 3- and 9-o'clock positions. When in the 3-o'clock position your knee should be aligned over your forefoot. recommends dropping a plumb line from the bottom of your kneecap. If your seat is positioned properly, the plumb line will lead to the ball of your foot. A plumb line can be as simple as a string with a small weight attached at the end. One can also be purchased at a hardware store.
Step 3
Loosen the seatpost clamp bolts just enough to move the saddle forward or backward, depending on the adjustment needed.
Step 4
Place a level across the seat, once you've established your fore-aft position. The seat should level. If it is not, tilt the seat in the necessary direction.
Step 5
Tighten the bolts seatpost bolts fully.
