(saw buzzing)

- Welcome back to What's Inside?

I'm Lincoln, this is Dan, and today is going to be rad.

- Rad, why is it going to be rad?

- Because we have ebikes.

- Ebikes, you ever heard of ebikes?

You ever seen these things?

We have some very cool ones for you today.

They're Rad Power Bikes.

Now it's cool, because they come in three different types.

They have the RadRover, which is kind of like

your off-road awesome mountain bike.

Your RadWagon, and it's kind of a cargo bike,

it has things set up so you can put pouches on the back.

We put our girls on there, and then we go cruising.

- This is a RadMini, so it folds up in half, super cool.

- Yes, and if you want to take this thing

and put it in a really tight, confined space,

you can undo it right here, undo it right here,

fold it down, fold it over.

We have five bikes, and unfortunately,

one of them is not going to make it through the day,

because we need to figure out how these bikes work.

You just start pedaling, and this engine just kicks in,

but you don't see an engine.

The wheel is really, really big and fat,

and so I'm pretty sure that that is where,

kind of the motor and the drive train is.

We need to try these things out,

go riding as a family with them.

I really want to take one of these ones

with the big fat tires, the RadRover,

up in the mountains, have Lincoln take his RadMini,

and see how well it does off road.

(acoustic guitar music)

We got the girls out here,

and we've just been riding on these trails.

It's about 30 miles of trails.

These have a 20 to 40 mile range on them.

We can put the girls on the back of the bikes,

and then Lincoln can ride his own bike.

And so sometimes they'll choose the RadMini,

sometimes they'll choose the RadRover,

but, it's just a lot of fun out here.

We get stuff sent to us often,

for us to cut open, or people reach out and,

a lot of times we don't do videos on them,

because they may not be as interesting a product.

But this one, Rad Power Bikes, actually sent us these bikes.

And they also gave us a link, that's in the description,

that if you guys go and click on there,

and use the What's Inside link,

you can get $50 off of your own bike,

and then also supports our channel.

But we're stoked to be working with Rad Power Bikes on this.

But now, I'm even more stoked

to be in the beautiful mountains of Utah,

10 minutes from our house. (laughs)

Our house is right down there,

and we are all the way up here.

That is the Great Salt Lake out there.

We got the bikes all ready, let's go cruising.

(electronic dance music)

Lincoln's ripping up the hill right now,

trying to come up here.

Did you see how fast he was going up the mountain?

He was just zipping up, like literally up a mountain.

All right, my verdict is,

this is my way to mountain bike, with an ebike.

Holy smokes, that was ridiculous.

What'd we find, Lincoln?

- We found a huge puddle.

- When you go through the puddle, it's really hard,

because you have to go up a big hill afterward,

and the water slows you down.

But I just pulled on the throttle,

and then the bike just powered me

right up and over the top of the hill.

- [Lincoln] We're going to make it.

- [Dan] We good?

I don't know, it's close, it's close.

Put the mirror in, Lincoln.



- [Lincoln] Woah-oh!

- [Both] Woah!

- [Dan] Just made it, wooh.

- [Lincoln] Ah!

- I just wanted to try something here.

A little experiment, I wanted to see

if I can fit all three of them on this bike,

and see if I can still make it work, okay.

Lincoln's on.

- I'm on. - 10 year old's on.

- I'm on. - Eight year old on.


Are you guys all on?

- Yep, I hold on to everyone.

- Okay, let's see if this bike can do it.

- [All] Woah!

- Here comes a bump.

(girls squealing)

Yeah, we did it.

We have seen enough Youtube videos

of people cutting into batteries that,

it's not a great idea.

What really is interesting on here

is right down here by the gears,

Leifeng, Bafong, I don't really know what it is,

but that's where the motor is,

the thing that really propels it.

It's kind of like a Tesla,

where there's no engine in the Tesla,

but now in the tires, they have like a little drive train.

So giant battery, and then this little drive train.

I would love to cut open a Tesla someday.

- Someday, it will happen.

- It will happen, but for now,

we're going to go with the ebikes.

It can be a little tricky, because

there's all these little components,

and parts, and gears, and everything.

- But we're going to get in there.

- We will see. (laughs)

(saw whirring)

All right, time to get into this thing.

We're just going to cut our way into it,

I think that's really the only way to get in. (laughs)

It's probably not the only way,

we could probably unscrew a bunch of stuff.

Nice, that's a good start.

I just was thinking about, actually,

probably take off the power pack,

so that I don't get shocked.

Cool feature about this bike is that it has locks on it.

When you have five bikes, you got to find the right keys,

and we found them.

Now you take the battery pack off like that,

oh, no more juice.

All right, I feel a little safer.


Got 'er.


Yow, it's stuck on there.

That was a nice idea, but,

- How do you get it off there?


- Well, there's our progress.

The tube, we got the actual tire

that had metal running around the edge.

It has this nice protector,

so the spokes don't go up and in.

And then you can look.

We cut all the spokes off, there's the engine,

that's what we're looking for.


This is what I want to call

the most ineffective way to change a tire.

(Lincoln yells)

Check out all the spokes that are still on there.

And we just went right through them, so now,

my next plan is to cut right down this.

Werp, werp, open that up with the bike still intact.

Sounds super safe.

Didn't want to have to cut into the metal frame of this guy,

but it's getting too hard, so.

Sorry, Rad Power Bike.

The bike chain.

Take a look at my clothes for biking today.

We got the chain on here, we got the motor in here.

I'm holding it by the kickstand.

- So now, it actually is time to cut this part open, right?

- I've been trying, though, I've been trying, look.

- (laughs)

- I tried to cut in there, and it was too hard,

so I just said, forget that.

I'm just going to cut the whole thing off.

It should be easier now that there's no bike attached to it.

But I got in.

- [Lincoln] Oh, you did?

- Check it out.

The motor.



Look at the engine on this beast.

Really interesting because,

when I turn the brakes just a little bit that way,

and then I go back,

the cuff spins inside.

- [Lincoln] Woah.

- It spins the opposite way, but it propels it.

See that?

Man, it's pretty intense.

Look at the engine in that thing.

It looks like there's magnets right along the side.

There's the metal, you've got all these

different cables and wires inside, these coils.

- [Lincoln] Chips.

- Lincoln, what was your favorite thing about these ebikes?

- Probably just riding around as a family.

That was super fun.

Last week was mug week, if you missed it,

you can go back and watch

our three mug videos that we did.

- It was fun.

- This week, we're going to do

alternative transportation week,

and we're going to do some pretty random

and pretty awesome things.

I always see videos at the end that say,

"If you like this video, give it a thumbs up,

"give it a like."

I've never done that before, but, let's ask.

If you like this video, give it a like.
