The Scorpion fs is HPVelotechnik’s  latest recumbent trike - it has the same basic geometry as the folding Scorpion fx, but it adds 6cm of suspension travel at the front. The front  suspension isn’t a simple bodge, either, it uses racecar-style McPherson struts and a stabiliser bar under the front wishbone which makes sure  that the trike doesn’t roll too much in corners.

I tried this personally at the IFMA show,  and it really works - the suspension smoothly soaks up bumps, and even  trying as hard as I could to get it to roll, it only moved a centimetre  or so.

The fs also, of course, has the same folding system as the fx - small enough  to fit in a Smart car boot!
