Having some technical difficulties, should be rectified soon.

This is a thing. What is this thing?

It’s been floating around eBay for a while, disappearing for a year or so and then reappearing with the same pictures if I’m not mistaken. It’s always at a price that would seem reasonable if it were in fact something that anybody knew anything about and was collectable. However, nobody seems to want to fork over $100 for something that seems to have absolutely no historical reference. It’s nature suggests that it might be a hand made one-off item, but then again, that strange metal plate doesn’t seem like it would be stock for anything I can recognize. Google it, and you’ll get pages of the auction description re-listed. On the Rat Rods Bikes forum someone linked to a patent from 1999, but I would have guessed this is older than that. I can’t even find anything on the Welin roller skate truck online. Is this skateboard-related? Maybe only marginally, but at least it’s not this. I’ve got an email into the National Roller Skating Museum to see if they know anything. As a side note, did you know Sure Grip International is still around?

UPDATE: In 2021 we learned this thing is called the Sit-Skate.

It’s a Sit Skate. Sit on it, Potsie. Slack jaw optional.

  • relax and sit down. and roll. And compress your genitals when trying to use the “front” pivot. The other way round sharpen the metal hub and cut it off neet & quick down the hill.
    Great thing ! The world smallest Luge !

    A Dollie for a musical instrument like a cello.

  • That metal plate has got to be to protect your hands when you hold on. Ingenious! The loop, for a rope? How is this not being marketed on youtube as the next big radical thing?

    I actually remember kids in India buttboarding down hills on metal wheeled strap on roller skates. Was kind of a big deal. There were even kids who doubled up on one skate. I still don’t know how that worked. They are grown up by now and probably wondering why they can’t have kids.

  • i remember those

    that plate in the front was a “brake”

    you squeezed it against the seat by your junk and the other end of it rubbed against the wheels “slowing” you down

    theoretically it was a cool idea

    in practice it really sorta sucked – you were better off just sitting on your board and draggin’ your feet

  • I recently bought one of these in sioux city iowa from a craigslist ad. Mine is yellow and, likewise, I cannot find any information about it. Do you have any information about them or at least an idea of how old they are?

      No idea. This is an old post and the National Roller Skating Museum never replied.

    It is a Sit/Skate made by Mark 10 Industries 1234 Nathan’s Lane Madison CT 06445 203- 245-7532 (I think) This info came off label still on one I just bought. Mine is blue and missing the skid pad on rear as shown above. Black lever is indeed a front braking system. A Black one is posted on WorthPoint web site. Will send picture of label to anyone who cares.
