Do I need a sissy bar with a banana seat?

[horsefarmer]

edh, Here is how I did the seat on my Gasser.

The seat post is part of an old Schwinn handlebar. I welded a small plate on the end so the seat clamp could not slip off. Also I welded steel flat bar over the chainstays to mount the sissy bar to.
Hope this helps you.

Thanks.
getting access to a welder again may be tricky as I would need to get the bike in to work. I was thinking of some sort of u shaped piece on the bottom of the bars to slip over both the chainstays and out it through to make it tight. Either that or borrowing a drill and drilling a hole in the dropout plates

Thinking you may need to put a wheelie bar on the back if you place your seat too far aft

Yeah, the front end gets a bit light on steepish ramps already. Though I won't be sitting any further back, my bum just won't overhang the back anymore

I just thought I would say, thank you for your kind responses to my (most probably) stupid and possibly repetitive questions, I spoke to the local bike shop and the mechanic said that I should have enough thread to clamp the sissy bar under the wheel nut which makes life easy. I did scrounge up a longer axle from a multigear bike but I won't know if the thread is the compatible until I get back to camp (where the bike is).

No such thing as a stupid question,that's why this site is here. So us noobs can learn these things.

Looking at your current set up, you may be able to flip your seat clamp back to front and gain 2 or so inches... Might get you by until you get the banana sorted...

The tube clamp is already at the front, if I flip it I will push the seat further forwards.
I will need to see what happens with the lay back post and banana seat, if one or the other doesn't work out I have an old indi 500 three speed that would benefit from one or the other.

Cool, I wasn't sure by the photo....

No worries, I hope I didn't sound too abrupt, I have put a backwards slope on the current saddle which helps as the back of the seat doesn't stick up into my bum but I still overhang it.

I have made up 2 support bars out of DIN rail, I 2 as looking round at what we have laying about and it seemed perfect, it is slotted too so I drilled out the lower 5 slots to 10.5mm which will give me height adjustment and I have left the rest of the slots standard at around 6-8 mm which should be fine for bolting the seat too, I will just need to see if it is uncomfortable (I.e.digging into me)
