How to Get an Extremely Low BMX Seat

You can avoid injury with an extremely low BMX seat, especially if you are the kind of biker who spends a lot of time doing tricks in the air. Your legs take the impact of landing, your knees bend to absorb the shock and your back side avoids smashing into the lowered seat. BMX riders often refer to this style of seat as "slammed." Your bike seat may be designed to be slammed, or you may have to modify it.

Instructions

    • 1

      Look just under your bike seat to unlock your seat post. Your bike may have a lever to release the seat post, or it may require an Allen wrench. Unfasten the lever with your hands or insert the appropriate Allen wrench and turn it counterclockwise.

      Place the palm of your hand on the seat and push it down as far as it will go. Look under the seat to see if any of your seat post is exposed. If there is no seat post exposed, then your seat is slammed to the frame.

      Mark the seat post if any post is exposed. You can use white-out, colored nail polish or use your miter saw to make a scored mark. Mark the post where it exits the frame, then pull the seat out of the bike.

      Measure the post, from the mark to the seat, with a ruler. Slide the ruler down to the bottom of the seat post and make the same measurement from the bottom of the post. Mark the measurement with white-out, colored nail polish or score it with your miter saw.

      Slide the seat post into a miter box. Line up the bottom post measurement mark with the saw slot on the miter box. Hold the seat post in place and saw through the seat post on the mark.

      Discard the sawed off portion of the seat post. File the bottom of the seat post to remove any sharp edges. Slide the modified seat post back into the bike.

      Push the seat down as far as it will go. The post should slam completely into the frame of the bike. Tighten the seat in the appropriate manner, using the lever or Allen wrench.
