Unknown dutch diesel bike & tranny question!

[Tetronator]

Hey guys!

I've seen this one around a couple of times allready but, I cannot find anything about it on the site or anywhere else for the matter. (And thats a dutch license plate!)

I know its a FWD VW lump mounted longitudinally with one end of the transaxle welded off and the other driving the rear wheel trough some sort of gearbox...
But heres my question! How does this guy shift sequentially whilst still having the original VW transmission? Because I believe VW uses normal "H-pattern" manual transmissions.
How does this translate to a sequential shifting layout?

Also more info on this bike and its builder would be welcome!

(If I put this in the wrong section im sorry... )

I believe the gear box is a standard industrial right angle gear drive. Someone mentioned about either this build; or one similar, about using a right angle gear drive from a tractor or earth working machine? try searching for "Right angle gear" or similar verbiage in here. Do not know about the tranny shifting. Could it be the automatic?

I was thinking about that too, but if it was an automatic. Why would he need an clutch lever?

Doubt it's an auto - the gear levers are clearly visible at either end of the foot board in the first few seconds of the video.

Though to be fair, with the mad-cap ideas some of us have on here those two levers could be for all manner of other purposes. Operating a mini bar on an extending arm from the trailer for example .

Can't find any pics but I believe the Quasar used a "rocking" 2 pedal foot gear change but in reality I think with the torque of a diesel you probably won't use all the gears anyway??
For example only use 2 and 4??
2 other options might be a straightforward hand change or some sort of solenoid operation??

I like the mini-bar idea but do you think the 'clutch lever' is for dispensing the right amount of martini for your cocktail or for the ice shavings?

I dont think its only two gears, looks to well build for that. Maybe the heel shifter is for longitudinal movement and the toe shifter for transverse movement in the H-shift pattern of the transmission? Would be very tricky shifting tough...

I only mentioned 2 gears because mouse ran one with no gears and just took off with lots of clutch slip till about 20mph and found the torque of the diesel was enough throughout the rev range.
I believe anyone who has had a VW beetle trike also finds that some gears are not really needed due to the much lighter trike so a 4 cyl diesel car engine should have no trouble.
Some people have used 2/3 speed agricultural gearboxes from mowers etc.

My only comment would be that possibly a centrifugal clutch similar to the one Volvo/Daf used in their later cars(not the whole CVT) which was a vacuum operated normal clutch might help the need to slip the clutch?
The obvious solution would be a fluid flywheel but I'm not sure one could be adapted for bike use??
If it was me I might consider an Aixam CVT mounted sideways and do away with the bulk of a car gearbox??

Yeah I guess that'll work then just using those 2 gears, maybe he has a hidden lever somewhere where he can jam it into 5th gear or something? If he just used the center part of the H pattern, assuming its a 5-speed with reverse, that would mean 3th and 4th gear. (He should've used a hand shifter in that case! Way cooler... )

That bike is the dieselross , made by Stephan Sanderse.
Unfortunately Stephan is not active on fora.
As far as I know he uses the original VW gearbox and a 1:1 rear bevel.
There is a fair chance he will show up at the TEXEL automotorentreffen , at least he was there 4 years ago

Thank you Nanko! I was thinking of going up there anyway! Oh, by anychance is this your creation?

Just a guess assuming you are also dutch and your sig says you have a Peugeot diesel guzzi.

Hi Alex
Yes thats my baby

Hi Alex

Sweet, I've been looking into a similar setup for my build or going the way of Dieselross. Not sure yet... So many possibilities!
Alltough I was planning on starting along the line of a shaft driven dry clutch system like your Peuguzzi.

Eitherway! Thats a great bike you've got there, hope to see it in the fles...metal? someday!
