  • So I met a girl a couple of weeks ago who is in a wheelchair.

  • Now, wheelchairs are great for pavement and flat surfaces, but not so much for off-road

  • adventures.

  • I secretly built this off-road wheelchair by tying 2 electric bikes together with a

  • seat in the centerkind of like a chariot of sorts.

  • It goes 20 miles an hour, with a range of about 20 mileswhich is pretty cool.

  • And this video shows how I put the whole thing together.

  • If I were to build it again though, I would get bikes that have a suspension in the rear

  • as well as the front, so it has a smoother ride while off-roading and going over curbs

  • and stuff.

  • Let's get started.

  • [Intro]

  • So behind me I have two normal electric off-road bikes with the super big fat tires, and we're

  • going to try to combine these 2 bikes into an off-road pod racer, chariot of sorts type

  • contraption.

  • A contraption where someone can sit in the center between the two bikes and still be

  • completely stable.

  • So the goal here is to preserve as much of the structural integrity of the bikes as possible...trying

  • to leave them in pretty much the same condition as they are right now, since a lot of planning

  • probably went into the design of these bikes and we don't want to change too much of it.

  • We want the rigidity, the safety, and the security that is already naturally built into

  • the frame.

  • We just want to modify it a little bit.

  • Okay, so one of the structurally sound points of the bike is right where the pedals intersect

  • with the frame.

  • So we're going to use that as one of the strongest points for this chariot pod racer thing we're

  • going to make.

  • So I've cut this bar.

  • We've already removed the pedals, and we're going to stick this right between where the

  • pedals used to be.

  • It falls apart just like that.

  • So even with just that one bar in between where the pedals used to be, this is already

  • super solid.

  • The thing I'm excited about is that the brakes are still intact on the rear and the front

  • and the front shocks are still intact, so it still should operate as one bike would,

  • except for we have two.

  • [Sawing noises]

  • [Welding noises]

  • So those tacks should hold it in place just long enough to situate it on the other side

  • of the bike.

  • So let me show you where we're at with the bikes.

  • We just finished welding up the seat frame which is going to be the perfect size for

  • the current cushion she has on her wheelchair.

  • Made sure that was the right size.

  • So luckily the seat's resting on the back of the frame, and then it can just rest forward.

  • And I want the seat to be slightly elevated back, so when she's driving around, she's

  • not going to slowly slide off the front of the seat.

  • So it's going to be raised up a little bit.

  • We have that bar down there.

  • So that should be the perfect distance to keep her on the seat while it's moving and

  • for her legs to go downward towards the middle of the front wheels so we know that this bar

  • is secure where the pedals used to be.

  • We have this all-thread bar right here stuck through the bottom brackets, all the way through

  • the bar, screwed in with some massive washers, a locking washer, and then a nut.

  • And that will keep it tight the whole time she's on the bike.

  • So you can see the excess of the all-threads sticking out on this side.

  • Obviously we'll cut this off before we finish.

  • We're just making sure that it's all in place while we finish fabricating the seat.

  • So far I'm pretty pumped that it's turning out.

  • I think it's going to work.

  • [Welding sounds]

  • It's pretty cozy for me.

  • Should fit Cambry pretty well.

  • Right now, only one bike is turned on.

  • We have the seat all welded into place.

  • The steering wheels aren't tied up in tandem yet, but I think we have that figured out.

  • But right now I need to hide the bikes because Cambry's coming over.

  • Ha ha!

  • This is awesome!

  • No way!

  • It's working!

  • And that's just with one bike motor moving right now.

  • So stoked.

  • This is awesome.

  • Okay, so the bikes are strapped together.

  • We have the seat basically built.

  • We don't have the leg extensions yet.

  • We want to figure out the steering just in case we have to tie into the metal for the

  • seat.

  • We think we have it though.

  • There's a little hole in the front of the shock where a light is supposed to go.

  • We're going to use that hole and drill in this angel bracket.

  • It's kind of like something you'd hold up a shelf with and we're just going to cut one

  • of these sides off, have it extend out, and then attach the two with the metal bar.

  • That way, the front wheels are locked together, so if you turn one, the other turns with it,

  • and they won't bind up while you're driving.

  • [Sawing and drilling sounds]

  • Right here, we went with the bolt right through the top, and then a washer, then the metal

  • bar we just drilled through, with another washer right between them, the stabilizer

  • right here, you had another washer, and then a locking nylon nut between them all.

  • Then when we tilt the steering wheel back and forth, both tires turn in tandem.

  • We have the front bar in that ties the front two wheels together, so they turn in tandem.

  • And we have the seat, and the next thing we're going to work on is the leg rest.

  • Now, initially I thought that she would be able to sit here and then extend her legs

  • like she's laying down, but that would block the wheels from turning, so there would be

  • like a metal cage right here, and so she wouldn't have a very tight turning radius.

  • And I feel like it's way more important to have a tight turning radius, so we're going

  • to drop her legs straight down.

  • So her legs are almost at a 90 degree angel coming off the seat and dropping straight

  • down to rest on the foot rest.

  • [Sawing and welding sounds]

  • So this is how the steering is normally, but if we take it and turn it, drop it down and

  • rotate it backwards so it's parallel with the wheel itself, and then tighten it down

  • with these bolts right here.

  • Then the wheel will turn when the steering wheel is parallel with the tire.

  • And with the throttle right here and right there, she can control both the motors independently

  • of each other while she's driving, and her field of view is still wide open.

  • We're just getting rid of all the stuff we don't need on the handle bars, like the little

  • bells, and also the gear shifter because we don't need that because no one's going to

  • be pedaling on this bike.

  • [Sawing sounds]

  • Okay, so we have both the handle bars cut off the front which turned out pretty sweet

  • looking.

  • We have the cable wrapping around the side.

  • Looks pretty minimalist.

  • The computer still sits very comfortably right there on the inside of the handle, with the

  • power switch and the brake, which can just be accessed with your thumb.

  • But now it's time to work on the back.

  • So I've taken a look at her wheelchair and I'm going to kind of design the same little

  • footrest thing we were using before, take that, and put it right here on the back about

  • 11 inches up, which will clear the tire just barely, and then come down here on the other

  • side.

  • And then probably use some flat plate along the sides and the bottom to keep everything

  • secure, and for somewhere to put her pad when she's off-roading on this bicycle.

  • So I am definitely not a professional welder by any means.

  • But welding is actually pretty cool.

  • With welding, we're running electricity through this metal.

  • So we have a ground right here, we can clamp it anywhere to our work of art that we're

  • constructing right now.

  • And this gun right here spits out a little bit of metal each time I pull the trigger.

  • And it's part of what conducts the electricity and helps melt the metal together and adds

  • a little bit of metal to the joint that we're making.

  • It's pretty solid.

  • I can move the whole bike with it, but I'm not going to put a lot of pressure on it yet.

  • Once we pull this out of the bike frame, I'm going to solidify all of the welds we've made,

  • and then I'll put the bike back together for some testing.

  • This is all the metal for the seat...the frame anyway.

  • We're going to put a metal plate over the top.

  • The back is at a slight angle towards the rear, but that's fine because the seat is

  • also a slight angle up just a tiny bit...which you can see a little better right here.

  • The seat is up and the back is just barely tilted back a tiny bit.

  • [Welding sounds]

  • So this is the back of the chair.

  • I've added some straps from the back to the base.

  • This is where she will sit.

  • And then down here at the bottom, we want to support the leg structure.

  • So I'm going to take this bar, and put it right behind these two for a little added

  • support.

  • And you'll see what that looks like when it's back on the bikes again.

  • Is that supposed to be on fire?

  • [Welding sounds]

  • Yes!

  • Woo!

  • [Drilling sounds]

  • She is ready for a test ride.

  • We got the foot thing in place.

  • I'll still clean up my welds a little bit later.

  • And then we have the side of the chair bolted into the frame back there with that little

  • u-bolt,which keeps things super secure, especially at high speeds.

  • Which, since this thing is capable of 20 miles an hour, being structurally sound is a good

  • thing.

  • Okay, so far it's holding my weight – 200 poundsright there on the foot rest.

  • Not too shabby.

  • It is cozy!

  • Okay, okay.

  • Both computers are on.

  • Oh yeah!

  • Yeahhhh!

  • Okay, this is the coolest thing I've ever made!

  • Both brakes work.

  • Probably find something to do a parking brake at some point.

  • I think it was a success.

  • Okay, so I dismantled the bike one last time so we can powder coat the seat.

  • Powder coating is a type of really really thick paint that gets cooked onto the surface

  • of the metal to make it look, you know, a little bit more professional than kind of

  • what we've been doing here.

  • The metal fabrication can probably be fit to any size, even a double-wide, if the metal

  • is rigid enough.

  • It's hard to say without trying it out for sure.

  • It'll be fun to see what you come up with.

  • Hit thatthumbs upbutton, and if you ever end up building one of these off-road

  • wheelchairs...go karts for yourself, I want to see it.

  • Cambry had no idea I was building this bike, so her reaction to receiving it was pretty

  • fun.

  • I'll link that video up here and down in the video description as well so you can watch

  • that.

  • Maybe you know someone who could use this, or you just want a sweet looking go kart for

  • yourself, it's pretty fun and powerful.

  • Feel free to share this video.

  • Thanks a ton for watching.

  • Hit that subscribe button.

  • And I'll see you around.

So I met a girl a couple of weeks ago who is in a wheelchair.
