[HowTo] Ghetto pivotal seat

[band aid]

I was messing around with my seat’s guts today and thought of a way to make a ghetto pivotal seat. Some people may think that this is a really stupid idea, but I will write a how-to on what I did. First of all, just to warn you…your seat will be pretty flexable if you do this mod. Also you probably won't be able to re-convert it back to normal. Anyways...

Materials: Seat, Seatpost, Hacksaw, allen keys, a staple gun, a flathead screwdriver.

Step 1:
Get an ordinary seat [the kind with rails]

2: Now you will need your hacksaw.
Cut along the red lines shown here with teh hacksaw, so that you can remove the rails form your seat.


3. Now once you have cut along those lines you will need to pop the front part of the rails out of where you just cut, then pull the rails out of the back of the seat so they are removed.

4. Now you have your rails removed, you can get started.
4.5. you now are going to need these parts of the seatpost.


5. Place the seatpost itself on the seat
like this.


6. Now mark where the holes in the seatpost line up on the seat.
6.5. Now strip the cover off of your seat.

7. Drill out holes that are slightly larger than the bolts in the seat and through the foam where you marked.

8. your seat should now look like this.

except with no cover.

9. now you are going to need nuts to match with your bolts.

10. place the nuts on the top of the seat where you drilled the holes. [I]glue them down. this is really key if you want it to work easily.

11. now you can recover the seat. By placing the cover back on and stapling it underneath. [ i didn't staple mine because i ran out of staples]

12. now you have your holes drilled and bolts installed, you will need to put this piece centered between the holes.


13. now you want to put the post over top of the little piece like this.


14. once that is done. you need to make sure the post's holes are aligned with the ones in the seat. now you can put the bolts in loosley.

15. now adjust the seat to the position you like, and tighten the bolts.

note: with my seat. the back of the post was touching the seat, and i added washers to the front bolt.

like this:

16. now you can install the seat on your bike.
and it will look like this. [my seat is a shadow slim sltripped and then thin padded]




now many people will say this sucks and is a bad idea for [who know's what] reasons.
but it worked for me and if you follow my instructions carefully it should all work out.

feel free to criticize and compliment.

[KoolAidGuy]

pretty cool but i wouldnt do it

[band aid]

i just did it because i am low on cash and i wanted a pivotal seat so i made a homemade one!

[Gtking80]

:clap:good idea!

[hoffmankevin101]

would it work with a chunky seat...like a primo baLANCE.

[band aid]

thanks!
gtking80

there is probably some better ways to improve on my design but it is a good start i think.

and it should work with any seat, you just might need to play around with different bolt lengths or something.

[gtbmx0222]

damn thats a cool idea!
now all you need to do is do the wedge mod and youll have a totally ghetto seat!

[Coldow91]

Awesome!! I think I am going to do this to my haro seat to see if it works well for me. Then do it to a seat that will look good.

[band aid]

damn thats a cool idea!
now all you need to do is do the wedge mod and youll have a totally ghetto seat!

you couldn't do a wedge mod with this setup because of the way it works.
although if you were to drill a hole in the pivotal peice and drill a hole in the seat. then you would be able to drop a bolt down into the seatpost, that is if there was no i-beam*.
DAMN!

*i-beam
a seatpost with a beam through the middle
ex.

[Coldow91]

What seat post did you use?

[band aid]

i used a coalition post.

[band aid]

well.
i went down to the local park tonight, so i guess you could sya it was the first time to ride it. and the seat held up great. actually, i was trying to manual up a 6ft bank and looped out. i fell to my ass from 6 ft. and the bike landed on the seat. nothing happened. so you could consider this still fairly strong.

[band aid]

i was just tigthening mine after readjusting it [the angle]
and the nuts started spinning with the bolts, because i didn't glue mine down, so i had to strip it and i tried gluing them and the glue broke out. because the bolts were cross threading because i didn't glue the bolts over the holes.... so it is very importatn to glue the nuts down. and make sure they are possisioned properly.

[band aid]

any more comments.?

[band aid]

no?????

[fitbike61]

ive done a mod fairly similar with the same concept of bolting through the seatpan and the second i sat on it, the seat pan failed on me and my ass fell straight on the tire when i was riding. and if urs is strong now, i doubt it will stay that way because even macneils overtime flex. but im pretty sure u already know that. whats all that white stuff on the bottom?

[band aid]

it's masking tape^
i had no staples.

[fluorescent]

Random. Never heard of a pivotal seat. What does it do?
Pivot I guess...

thats not an i-beam seatpost.

this is an i-beam seatpost

i know people call those internally reinforced posts i-beam posts, but they really arent.

[band aid]

oh i see.

[bikerinthebuff]

wicked idea i just cant figure out how you did it. your how to doesnt make sense to me. i still cant picture it.

[band aid]

hmm... it is fairly simple.
i might re-write it.

[band aid]

1. Take your ordinary seat.
2. remove the rails in whatever way you want.
3. now center the post on the bottom of your seat.
4. now while the post is still on drill out the seat, in the same place as the holes in the post.
5. now glue your nuts on top of the seat, where the drilled holes are.
5.5. recover your seat.
6. now place the pivotal piece centered in between the holes on the bottom.
7. now insert the bolts through the holes in your post. Then through the holes in the seat, into the nuts you glued on.
8. now tighten the bolts when the seat is in the position you want.

simple revision.

donno if it helped.

[band aid]

anyone else wanna comment?

[sledneckadam]

Sick Idea I gave you rep point's for it!

[band aid]

thanks man.

[sledneckadam]

No problem :D

[social]

Wouldn't it be smarter to just hold the top bolts with a socket wrench or whatever, and tighten the bottom ones I imagine you could get it alot tighter and then put your seat cover back on...

[band aid]

well. ya. but it is harder to get the cover on then. and then when ever you want to adjust it or take it off you'd have to strip it.

[social]

well dont adjust it i guess? You should put ghetto pivotal seet in quotes.

[DocAvoido]

interesting, people sure make some crazy mods.

[band aid]

yea. i am alwyas moding my bike.
in anyway i can think.

and you're right social you can't adjust it. so it isn't really pivital. but it does save a tiny bit of weight. and it looks cleaner and makes your seat even lower...:roll:

yeah. most people won't care about that stuff. but i do so if you want to have your seat even lower. try this.

[Alex Steadman]

My friend has a pretty sketch bike so we always test everything out on his bike, and this probably won't be an exception.

[band aid]

cool. hope it works for you...

[Wildbill]

I have somthing better than a pivotal post..

[band aid]

yea^ i have seen those before. How do you like it? do you have a pic of it on your bike?

[made in bangkok]

pretty smart idea man. does the seat ever move though? find a good way to stop the nuts spinning when tightening it and you've got it sorted!

[band aid]

do you mean like the angle or side to side?

whatever.
it doesn't move if you have it tight enough, but the seat flexs a bit, because there are no rails for support...

i am still working on an idea with the nuts spinning...

[123odyssey]

congrats on thinking up that mod man, ghetto for sure. I love new mods:)

[band aid]

me too. i am always cooking up something lol.

[BlakByke]

me and my friend did this and it snaped right away

[band aid]

you probably used a really thin seat.

i was thinking about using the rails and bending them so they fit onto the bottom of the pan. to give the seat more support^...

[bmxer608]

This is a good idea. You can also do it with a seat with the rails mest up. For example I have a shadow crow seat. The part of the seat you sit on came totally apart from the rails. My dad and I fixed it by drilling the slots in back where the rails fit into and drilling the part in front where the frant of the rails fit into. We had to do that because there was no other way to put the rails in those slots with out bending the rails. Then he found some screws that fit and srewed it in [the screws on the nose] If it ever messes up again I think we might do this. That way I will save money. The only con there is about this is you can't move the seat posistion after you do this [tilt front or back] with out taking the cover of the seat back off. Or can you change this at all after you dril lthe holes?

Now I noticed I can' do it because my seatpost is justa straight pole, it doesnt have any guts so it wouldn't work.

[band aid]

no you can change the position. when you take the post/bolts off the seat, just space the front bolt more or less to angle it accordingly.

if you know what i mean

[screwglue]

well this is a good idea, but the thing is pivotal seats were made to save weight, and this isnt really saving weight, beucase pivotal seats are plastic making them lighter.

[band aid]

this looses the weight of half the post and rails...^

[diablo90]

i have an idea.....its alot the same thing

but rip the cushin off the seat and drill a hole threw the plastic

put the wedge and then use on of these babys

bolt and nut



hopefully u guy get the idea
i think it will work better.....since its way tighter

[band aid]

i don't get it?^

[manulin matty C]

I just wouldnt run it if u want a pivotal just buy one. your seat and post was better before. or I guess u just wanted to be trendy

[band aid]

no. actually. i like to mod my bike. so i thought of this and decided to try it and imo it is cooler than having your typical seat/post.
