It pivots at the front near the bottom bracket. This pivot is held to the chassis at the top. The entire front axle then pivots from near the bottom bracket as a live rear car axle would. The boom acts as a single trailing arm. The front pivot seems particularly poorly supported.
Not looked that far away for the pivot !, I was looking for something mounted on the floor DOH
I assume you are talking about the large rod end bearing that can be seen in the 2nd picture.
I like the Velayo like rear steering. It's moving the steering to the rear that makes it possible to be so narrow.
Yes I am going to say something really stupid about rear steering , I am wondering if it would help a tadpole trike get through my street furniture obstructions ?
He has reported steering problems ?
Rear wheel controlled velomobiles are sensitive to instability when driving straight ahead. You cannot let go of the handlebars because the bicycle immediately sends a side under the influence of, for example, a slight slope.
Also reports ...
The bike now drives straight, but the steered wheel still responds fairly immediately to unevenness and holes in the road. The solution is a steering damper. They come in many variants and even a gas spring can be the solution.
Someone in the comments said:-
If you tilt all the hinges a few degrees, you will also get straightforward stabilization, which is a much nicer solution.
