Wheelchair ski

It's very difficult to drive through the snow on a wheelchair.
Some brands designed and sell wheelchair ski, but the price is very high.
Another disadvantage is that a user has to remove ski on the road and put back on snow.

We designed a wheelchair ski that you don't need to remove each time as a small portion of the wheel goes through the blade and gives you an ability to go on any terrain - roll on asphalt and slide on snow.
