While browsing, I've just stumbled upon this. Anybody have any experience of it?
Universal bicycle shock absorber. Protecting your knees and smoothing the ride

The problem with it that I see, is the front angles more upwards, at every jolt.
Directly in an area (where all men are a bit differently sensitive), but one has to be careful. Furthermore there is a blood supply and nerves, that some bad saddles already press on "underneath" in our "sitting area", without being sprung....
If the spring could be mounted 180° in the opposite direction, there might even be an extra positive effect, particularly for men, less front pressure on the nerves and pelvic area.
I do not know if women suffer in quite the same way as some men "down there", and whether this spring would be positive or negative for them I really have no idea.
I certainly would not pay out any money for such a unit.
I have had and used the conventional saddle spring shaft, which only goes vertically up and down, when I have had hard tail bikes in the past, with very positive effects.
But I find independent suspension at both the front and rear, to be the most comfortable for me personally. Furthermore, with regard to heavy items on e-bikes such as the owner and a battery, the strain on the frame must be far less with a full suspension.
Its all a matter of taste, but guessing only, I bet this unit is a) far more expensive than the usual saddle spring and b) this might possibly break, after some years use for a heavy rider, with the possibility of severe damage to a very sensitive area.
So I would not trust it either.......
I now see that it costs $59 plus shipping....I could buy several of the tube springs LOCALLY for that and still have a lot of change!!
The Hyper Marketing video also does not appeal either...I personally find that suspect, and more a way to drive up the price, for a simple piece of spring steel and mounting!
But many thanks for bringing it to our notice.
