This is the original, not a knockoff.
Like getting a free bike because the kit by itself goes for over $500.
It has been sitting in its original unopened box in my basement for the last 5 years. Just got around to putting it on a bike this winter. You can see the plastic still on the ski in the picture. Comes with the bicycle which looks messed up but it’s not. It was kept in the city and locked up on the street so the flat black spray paint splotches on it were to make it less appealing to a would be thief. It’s a nice Specialized bike in great working order. Selling because I am 62 years old and find it hard to ride with my bad knees. I think if you are interested you should be a bit younger and in good shape. In the Youtube link you will see people having a ton of fun on these things. Basically they are mostly going down hill at a ski resort. It would be great for that! And if so, you don’t need a brake because you are using it like a ride-on ski. Skis don’t have brakes. In my experience with it I doubt I would ever wish for a brake on the thing. I would wish for power assist though. lol. Anyways, yeah, it doesn’t have a brake because I didn’t get around to making it happen. Also comes with a protective cover/carrying case. Thanks for looking. Cheers!
