S-BIKE full suspension!!!!!!!!!!!!!!!

I was told about this one a few days ago.

I'd suggest staying clear of it unless you're prepared to spend a lot of money. Not only does it not have brake bosses, it doesn't have cable stops as well.
To top it off, the headset is at a very steep angle. You can even see it in the pictures.
A quick measurement in Paintshop told me that the seat tube is at 71°, which is about right for an Sbike. however the headtube angle is closer to 80°, while it should be 72-ish degrees. Drop the forks to the normal height, and it becomes even more steep. This bike would be really unstable.

Also, the rust indicates that this is a CroMo frame, whereas all Sbike full suspension models were 6061 aluminium. I really doubt that this is genuine.

If this is indeed a prototype frame, it's one they didn't finish because they screwed up when they welded on the headset.

Maybe worth a bid because of the forks, but that's about it. If anyone buys it for that reason, I'm offering around £50 for the frame alone, to hang it on the wall.
 
I really like it its apart of S-Bike trying out different styles of frame tubes, don't think this frame was ever intended on being used just a mock up. Nice piece of S-bike history there for a collector 8)

Was this frame before the suspension model ever came out of after suspension bike they made in red forget the model number :roll:
 
Those welds look too fat for steel. The angle of the head tube does look unusually steep, but it may have been designed for a really long front fork, which would slacken it out some.
 
Look at the last picture, Sancho. Those brown spots are clearly the sort of surface rust you see on bare steel. Aluminium oxidation doesn't have that colour.

As for the headset angle : Even with those Manitou fors like that, the angle I'm measuring is 80°. Sbike downhill models always have a 72° headset angle, except for the 908 which has an angle that can be adjusted from 71 to 73°.
To get to those 72° with this frame, we're talking at least 200mm of travel.
Putting in a fork of that length would also move the seattube angle down to 63°, which is way too shallow even for a pure downhill bike.

There's something odd about the swingarm pivot as well. It's just a metal plate, and the axle and caps don't look right either.
Looks more like a homemade replica that got messed up than a prototype made by an actual manufacturer.
Sbike may not have the best reputation, but I seriously doubt that they would get it that wrong.

The more I look at this bike, the more I doubt that it's a real Sbike.
 
the welds look big for steel , but not big enough for aluminium

i'd say steel tho the "rust " looks quite prevelant to be just tarnishing

hmmmmm..................
 
Certainly ain't aluminium, mikee. The swingarm section around the pivot is just 4 or 5mm thick. I really doubt that could handle the rider's weight if it were aluminium.

To me the "rust" looks like tarnishing that's been removed. I think the entire frame and swingarm had a thin coat of surface rust on them, and that's been rubbed off.

I'll take some pics of my Sbikes' welds tomorrow (gotta go to bed now or I'll be in trouble in the morning). I have a CroMo frame, a Cro-Mo post-production frame and an aluminium frame here, so it should be easy to compare the welds on those.
 
I think its alloy :? I really dont think those spots are rust,looks more like grease :?
Given its approximate age do you think bare steel would still be bare :wink:
 
it looks like its been rubbed up with a loyblox (sponge sanding block)
looking at it on a proper monitor id say steel
very nice welding tho
the seat post struts look just like my 504 ones too

you going for it bulls ?

get in there man :lol:
