So today is the first legitimate test of this 4-wheeled, off-road, we don't really have
a name for it yet, but off-road wheelchair I guess you could call it.
Cambry still does not know it's coming.
It hasn't been painted.
This test is happening before I send it off to get powder coated.
Cambry in the past has ridden this other bike behind me.
It's an electric bike with adult training wheels.
But it's not something I would really trust to let someone go ride by themselves because
a lot of bad things can happen.
If it tips over, there's literally no way to get back on the bike.
So this 4-wheeled off-road wheelchair is much safer, much more stable, and I'm excited to
see how it handles on this first test out in the wild.
Me and my little brother are going to take it on a hike of sorts.
He's going to drive it.
And we'll see what happens.
Let's get started.
[Intro]
And it is tied down and in place.
We are good to go.
Spencer, this is the bike.
What is your first opinion after seeing it for the very first time?
[Spencer] Happy to be a crash test dummy for this thing.
[Zack] Perfect.
[Spencer] Looks pretty good to me.
I don't think it's going to fall apart.
[Zack] Think it'll work?
[Spencer] Sure hope it does.
[Zack] So one thing I did design specifically was that the wheels are narrower than the
wheel wells in my truck.
I can just load the bike into my truck and don't have to worry that it won't fit between
those two bumps.
Okay, so both batteries right now are fully charged.
We're going to take it on a trail, so it's going to be more like a crawl and less of
like a speed race.
When Cambry gets inside of it, right here along the side, I imagine she's going to be
able to roll her normal wheelchair up and then do a transfer into the seat.
But for people who's legs work, it's a little bit harder because you kind of have to crawl
over the side.
[Zack] Are you ready to go?
[Spencer] I'm ready to go.
Let's do this.
[Zack] Ha ha!
It's kind of hard to get in.
Perfect.
[Spencer] Does it have a reverse?
[Zack] No reverse, but you can just grab the tires with your hands and back up.
[Spencer] Yikes!
(screeching power slide)
[Zack] Okay, how was it?
[Spencer] Ummm.
Who needs helmets, right?!
[Zack] Ha ha, okay!
[Music playing]
[Zack] So if you haven't watched the main video where we assembled this thing, I'll
put a link for that in the video description.
But basically we built this whole thing from scratch, just a little seat mounted between
two electric bikes.
And the electric bikes have a top speed of 20 miles an hour, with a range, I think, of
20 miles.
So 2 bikes in tandem, if you're using the motors a little bit here and a little bit
there, because each motor works independently, you should be able to go pretty far with it.
We definitely won't be pushing 20 miles today.
Today is more of just like the off-road portion of the testing.
But so far it's doing pretty good.
So Spencer is going to try to do this trail right here which is gravel and pretty darn
steep.
Alright, so there's a pretty deep rut on this side, so stay over on that side over there.
Peeling out?
[Spencer] Yeah, it's going backwards.
[Zack] Okay, so right here there's a lot of gravel and there's no traction.
So I bet an asphalt trail would work.
Let's get going on the trail.
So we discovered the bike is built more for speed and flat ground than it is for like
torquey and uphill...uphill adventures.
Which is fine, because most of the time it's going to be on a flat surface anyway.
So this is a gentler slope.
We should be okay on this one.
Oh, easy.
[Music playing]
Okay, good luck!
No way!
Ooo, lost traction.
Nice!
Yeah, one of the tires lifts up back here and he lost traction for just a second.
Kind of killed the momentum.
But overall, it's still worked.
Alright, so I found this little riverbed.
Spencer's going to come down here, come across this, and then we're going to try to go up
the other side.
Might be pushing the limits, but we'll see what happens.
Need more power?
Okay, I'm going to give you a little push.
Okay...that was... okay!
Almost made it.
You can see we started to peel out right there.
I think if it wasn't so muddy, and this whole thing probably weighs 150...175 pounds give
or take.
And then Spencer's weight on top of that...we just need more traction in the tires.
Good!
Oh boy!
I wonder if we had tires with a little bit more aggressive tread, because the tires on
this one are just tiny little niblets.
Aggressive tread might be good.
Ha ha!
All 4 tires on the ground, buddy!
How fast were you taking that turn?
[Spencer] This thing turns pretty tight.
I was surprised.
[Zack] It would be impossible for a normal wheelchair to go where we're going right now,
and that's with someone pushing it.
This is fully electric.
How much battery do we have left?
We still at 100%?
Still 100% and we've been doing hills for like what, 20 minutes now give or take?
It's impressive.
I think Cambry's going to be pretty excited about it.
Yeahhh!
Getting a little mud on the tires, but yeah, these don't
have a whole lot of traction when compared to like off-road tires or off-road mountain
bikes.
Okay, I'm going to follow you in my truck.
Okay, so now we're just going to put some miles on it.
These bikes are street legal because they go less than 20 miles an hour.
And so having 2 bikes in tandem should still be street legal.
We'll see.
[Music playing]
So Spencer just took the bike around this paved bike trail.
What do you think?
[Spencer] I'm pretty impressed.
I can go 20 miles an hour on either one of these just by themselves.
I wasn't too sure what to think about it at first getting on, but it held together.
Super solid.
Mass produce these bad boys.
[Zack] Is there anything you would change about the bike?
[Spencer] Just like positioning of the handlebars is probably the only thing.
[Zack] She is smaller than you though.
[Spencer] That's true.
[Zack] So we decided to keep the turning radius pretty tight so that like since there's no
reverse, these bikes don't have a reverse, the only way to turn around is with a sharp
turning radius.
Or, reverse can sometimes happen just with your hands on the back tires like this.
Just kind of like pulling back on them.
Alright, that is it.
We have put 9 miles on it.
I think it went pretty well.
It still survived.
Did some hills.
Didn't do other hills.
Huge thanks to my brother for helping me out with this.
Appreciate it.
He didn't die this time, so that's great.
We try to achieve that goal every time.
Thanks a ton for watching.
I'll see you around.
