Bicycle Repair/lowering seat


How do you lower a seat on a older mongoose bike

Bicycle saddle/seatpost height is adjust via a clamp/"pinch-bolt" mechanism as either a collar that slips over the Seat tube of the frame, or is part of the Seat tube of the frame itself. Either way, try loosening the bolt.  This should allow the seat post to slide down into the Seat tube of the frame. If this is not the case, the seat post and tube may have become "fused" or corroded, to the point where special chemical/thermal/physical "maneuvers" may be required to free the post.

I can answer most inquiries with respect to bicycle assembly, repair, tuning and maintenance. I am less than inclined to speak on such questions as "What kind of bike should I buy?", &/or "What is this bike worth?", etc. Any answers to these types of questions may correlate poorly to an acceptable "fact/sarcasm" ratio.
