This vehicle is absolute surprise. Can you imagine amphibian velomobile? I have seen some amphibian bikes usualy with ugly look but this machine is so nice!
It is a homebuilt velomobile with linear pedaling, hydraulic steering with steering wheel (!) and electric assist. And the most interesteing thing is that it can be used as a boat!
On the web page www.esoteric-david.eu you can find some more pictures from the building process and above pictures also 6 links to great videos. The best one is here which shows the velomobile going into water.
We hope to come with more information soon.
Oh, I forget. The name of builder is David Buchwaldek
