GoPed Knowped Kick Scooter Seat Build – DIY
Lacking proper knowledge but never letting that stop me, one of the best ideas I’ve had in a while is putting a seat on my GoPed Know Ped. Originally a friend, and my son and I, welded up a seat for my TRX Personal Transporter Scooter. We cut a seat post from an old bike and welded a foot plate on it. Somehow, without any planning or engineering of any kind, we built it just right. You can check out the ride in this YouTube video here that I made a while ago. It was unreal fun. BTW, the video is a parody of, well… We were just having fun.
Eventually the TRX wore out (sadly) so before I sold it to someone for a build, I pulled off the seat we made. One day I was sitting and looking at the seat and then my GoPed and started thinking about it. Turns out if I turned it around from how I had it on the TRX, it would fit on the board of the GoPed. Not exactly, but close enough. On the back bolt pattern that I realized if I used metal washers I could over-lap the GoPed frame support for the deck. Plus, I used wing-nuts, figuring I could easily take it off for travel. 
(Looking back, if I were making one now, I would try to drill the holes in the seat plate for the bolts to fit through the factory holes on the frame support.)
Anyway, I drilled the holes through my deck board where they already where on my seat post plate. Then I used bolts, large metal washers and large rubber washers to connect the seat plate to the board. I figured the rubber washers would act like a spring and compress the nut, holding it tighter. I prayed it would hold. I was right! I never have to tighten the nuts. It’s been unreal.
One more thing I did…
I wanted to fly with it when we go visit family. I did it once without the seat folding. I just took the seat off and put it back on. But that was kind of a hassle. One day, as I sat and looked at my pile of old scooter parts, something came to me. I had an old Schwinn electric scooter with the fold down handlebars. It hit me to take the handlebars and turn them into the seat post.
Here’s how I did it:
First, I took the handlebars out. Then I cut off the crossbar “handlebar” with an angle grinder. I had another seat piece from another scooter that slid down perfectly over the handlebar insert part that tightens. So basically I flipped the handlebars upside down. I basically mounted the foot plate where the handlebar was.
I took it to a local weld shop. They had an ENORMOUS machine that they used to cut the metal foot plate to size. We also cut braces. The metal with the cutting was $15. I brought the scooter in and showed the guy what I was trying to do and left it with him. A while later I came back and it was ready to go with nice welds. About $35. I took it home, drilled the holes and painted it. 
An extra step I took was to cover the bottom of the metal foot with rubber. I had an old motorcycle tube that I cut to lay flat, then used contact cement to glue pieces to form the solid bottom, then I trimmed it. I think this rubber helps keep things together and keeps it quieter. 
Then I attached it the same way as before, bolts with metal and rubber washers and wing nuts. 
It rides great, and I can quickly fold it down and put it in the trunk or a bag ready to fly. I can check it with the airline for free as my mobility aid and I just drop it off at the end of the skywalk with the strollers.
The folding seat has added a lot of functionality. Luckily, we made it just right so the GoPed handlebars are the last thing to fold and go right on top. When I slip on the web strap it is compact and sturdy. I did end up gluing another piece of rubber on the deck to prevent the sandpaper from rubbing my seat off.
I have been riding my scooter on a regular basis for about 2 years. It has been incredible. There is enough room to stand in front of it and kick. My grandkids like to stand on the deck and go for a ride.
The GoPed itself is super strong and capable. I ride it indoors and out, great for big stores. The front brake is a necessity for seated kickscooting. This scooter is tough. On a trip to a National Wildlife Refuge I put it against the back bumper of the truck to load later. Only I forget and drove right over the scooter with our trailer. Not a problem. I few things got turned or twisted, fixed easily enough and still glides like a champ. The scooter can go forward or back, turns tightly and is very responsive. Very easy to ride around people and in tight spaces. And when I ride it in stores kids stare at me like I am Santa! I would love to get a read one eventually.
GoPed Know Ped makes an excellent scooter, the seat mod makes it even better!
