BOBBER SEAT CONVERSION?

[Rat Rod]

Has anyone ever converted one of these motorcycle bobber seats into a bicycle seat?

I swear I've seen this done on the site before...

I'll be watching this thread. That looks a lot better than the seat options I've seen!

HD (motorcycle) seat pans are metal. It has a hinge front mount and 2 studs (threaded) for springs in the rear. With a cross-brace and the right springs, it's doable.

Here's one that I mounted on a custom bike, so you can see the idea.....

Front mount with strap hinge:

Rear with springs. Springs fit over studs from seat and held on with nut and washer.

Thanks for those pics!

I'm wondering if anyone has ever welded the tabs to the pan that would allow a regular seat clamp to be used so you could mount it on a seat post.

i will look into this .. but am thinking might need to reshape seat pan .. to move your legs freely

 

[CRASH]

Good point. It may be too wide for actual riding, even if you did weld the correct hardware underneath.

You could make a "T" bracket that would bolt onto the seat either with or without the springs with a seatpost welded onto the tee

For my Build off bike, I'm planning on using the seat clamp turned 180 degrees and some bushings to pivot on.
Then build a frame to mount it on the fender bracket

Not sure if that helps or not

the crazy electric straight 8 build thread just did a seat conversion. Not to mention all the RIDICULOUS AMAZING fab work on the front forks. It's intense.

Promise I'll have it better attached when done. The alternative sounds too painful :lol:
Kinda looking forward to making some brackets and they don't have to be too complicated

My wife got a big grin when I told her about the Hello Kitty duct tape,
Saw the gears in here head start to spin, thanks Buddy :lol:

I remember that now Gary...that's awesome.

How comfortable...or should I say, uncomfortable is that set up?

 

[XC204]

That seat is very comfey I have no leg extension on that bike but the seat is padded between the 2 layers of leather and I have ridden it to work 7.5 mi each way with no rear problems just my knees.

i kinda made one, but i used a single mountainbike shock for a spring

i'm working on a second one that might look a little closer to it (closer to the shape. still one spring but without the back rest and water bottle) . i've been riding on it but broke a weld. i'll take a pic when i put it back togeher.

 

[Philphine]

the second one

both were exercise bike seats where i got rid of most or all of the framework and made my own. i guess you could do the same with a bobber seat if you wanted that exact shape. i have to say though, my seatpost being angled back so far makes this easier (the second was really for a more upright seatpost but i couldn't work it out). you'd probaly need a much shorter spring like off a kids bike or something.
