Wonderful video, bro!
As soon as I saw the presentation of KS-S18 back in April I decided straight away - I must purchase it. Then when I saw videos with people riding it another wish came to my mind - to turn a wheel backwards and ride it with suspension looking forward. I don't know why but it stuck in my head since! So now I've got the wheel, did 160km (100 miles) and was ready to try to go on "backwards wheel". Yesterday morning I turned the wheel backwards and rode it to my work for 10km (6 miles). The ride was pretty good!
1). Wobbling was less, probably because the wheel above suspension is wider and my knees were touching the wheel thus allowing me better control of it and did not allow it goes from side to side.
2). The front side (with suspension) became heavier and due to this it was easier to start riding after stop - you just need to lean forward a little bit and you go!
3). The suspension worked almost as good as with normal riding way.
Of course, these are my subjective impressions. Maybe somebody else will ride it that way and have different opinion. Or maybe Redfoxdude can compare riding normal and "backwards wheel" and see if suspension works the same or differently? It would be interesting!
