I would name it Snake Wheel but the inventor think it looks
like a Shark maybe http://sharkwheel.com/

It looks very odd like it would wobble like a warped LP record
But he has tested and say it runs smoothly on hard surface
and much better than conventional wheels on sand beach.

So I come to think of snowy streets up north.

I live in Sweden and one would expect that they clean the streets
but if the snow has fallen at night they can not afford to pay for
all the needed manpower to take it away. Take days.

So I needed food and have fallen each winter due to bad balance
so I use a four wheel kickbike from Finland to take me to things
when street are slippery.

The wheels are only 12" so sure they get stuck in the snow.

But even the 28" got stuck for a neighbor who have studs
on his standard bike. He came walking and told me it was not
easy to use the bike. Very bumpy and hard work to go.

Now the inventor of Shark wheel say his pattern allow it to work well
even on sand that is not packed hard. The pattern behave like a sand snake
crawling S curve line. so much better tract

He will show it in action December 15 so that is tomorrow when I write.

Would be cool if it works as good as he say. I know nothing and have no relation to him.

this is not an ad for it. I have had problem with biking in snowy street for years now
so I want your kind comments on does it look like a good solution for winter bikes?
