Ok more work on prototype 2 ?
This is the mock up wood is @ 45' to blue horizontal member and threaded rod is @ 90' to the wood and meets the ground at <> 0"/cm trail so where it needs to be.
I salvaged a BB and short length of seat tube and with and insert and outer sleeve I can weld it to...
So damper fitted , however a bit of a disappointment really ?
Yes it is providing a small amount of damping , however not enough to hold the front up in most situations.
However it is heavy and costly and bulky and probably not needed ?
The Finnish Flevo builders reckon with a steering...
Well you know when you have that gut feeling ? what you are looking for is on the net somewhere .........
Over 25 years ago someone built them selves a FlevoTrike with 2 sets of handle bars !
It looks like he has a small set with no controls under the seat , maybe to help with take off and...

So my plan will be to send you the middle part of the mule .

It also has a upper frame mounted on the lower frame on...

And a bike and a trike both apparently traveling forward with the rider roughly upright and the front of the Flevo NOT upright !
I'm with him !
I don't think the brain could cope with dual function levers , especially in a panic situation ?
Also when I visualise this I see the bars being mounted on a solid rear end trying to connect to the moving front end.
The front goes up and down when it steers ?
The front goes...
On a less gloomy note I found this thread Finnish Flevo trike been in contact and have been given some guidance steering re-pivot angle trail etc..
Their conclusion was any pivot angle could work with 0' trail ?
They have used the standard Flevo 45' and just lengthened the front...
So it is back together with paint and lot's of either double nuts or lock nuts , cable ties etc.
A steering damper is fitted and has slowed the steering down and limited the lock , there is more lock right than left , however it is a left turn in the cul-de-sac and it makes that easily ...
