Hi guys as usually its me just a voice over and you are watching review machines and today
I’ll show you the simplest and cheapest ATV Motorbike, lets go!
We’ve already made several videos about offroading motorbikes and they became quite
popular, so we decided to proceed with this theme and today we have for you this newest
and pretty interesting vehicle.
By the way it is called SR-21, but I have no idea what it means.
But I know the main ideas of this bike – there are two of them: simplicity and minimalism.
There are only necessary parts in the construction.
Nothing excessive!
The manufacturer states as a result they got the maximum of reliability.
Besides such a solution allows them to make this bike one of the cheapest on the market.
The ATV motorbike SR-21 is designed to move on a rough terrain, on sand and snow in woods
and swamps and lets find out how it is made.
The frame is made of steel as we can see its very simple it is even easy to make such a
frame on your own.
The bike is equipped with Chinese engine Lifan 8 hp.
As a transmission there is only a variator and no any gearbox.
Then we see here a chain drive and the huge sprocket.
The handling is also the simplest there is only throttle and brake.
And there is a rear hydraulic disk brake.
The bike is quite minimalistic but it has the full suspension system of the both wheels.
There are front and rear spring hydraulic shocks.
I think it’s a good feature, cause sometimes there is even no any suspension at all at
such kind of bikes.
Moreover we have here a huge comfortable seat – it is like a cozy leather sofa.
Also we see here wide offroading low preausre wheels from an atv.
Then there is a comfortable box at the rear that comes complete with the bike.
There is only one front headlamp protected from trees.
And the bike has wide footsteps as parts of the frame.
Well lets move to the practice now!
Lets fill the engine and take some water, its such a heat today!
And now we try a cold start.
The engine is pretty standard, I think all of us know how to start it, don’t you?
No there is no any electric starting at all.
As I said this bike is designed for cross country travel and to move on a rough terrain.
It is good for fishing hunting and so on.
And now I want to share with you my first impressions.
Few words about the engine.
Undoubtedly this engine is not the most powerful, it is only 8 hp.
But is is quite torque for such capacity and besides the rear sprocket is huge that is
also provides good torque.
Such engines but about 15 hp are used even in big atvs, so in fact its enough power for
this bike, that weighs 99 kilos.
So I really can state the torque is quite good, and maybe it is not necessary to install
here a more powerful engine.
But most of all I was impressed by the suspension.
It is so soft with enough suspension travel.
Such a suspension do a lot of good for cross country moving, you almost don’t feel any
roots and hummocks at all.
This bike is really felt like a cozy sofa!
It is so comfortable to ride on it.
Lets look how the suspension works.
As I said it works pretty well due to the long travels of the suspension and good shocks.
Besides we should remember about big low pressure wheels and the huge soft leather seat.
Also the big footsteps provide even more comfort.
And while we are watching how it works, I want to say that all these features together
provide such an impressive and comfortable riding.
Yes it doesn’t equipped with all wheel drive system, but anyway we can call it an atv motorbike,
cause due to the suspension it allows you to move on a rough ground and get over some
obstacles like fallen trees, roots and so on.
It is very simple to handle the bike due to the variator.
I think everyone knows how it works and it needless to speak about it but it may be interesting
to watch it.
There is a good access to the variator, it is easy to dismantle the metal cover.
Certainly it is forbidden to move without the cover, but anyway lets see how it works.
As we see the belt is not rotating with the idle run, but when we push throttle it starts
rotating.
The more we push the throttle the more the gear ratio changes and the vehicle moves faster.
But its enough of it lets move on.
Our bike is not very fast, but anyway it is interesting to find out the maximum speed.
Well I hope you can see it, the maximum speed according the gps is 45 kmh.
Meantime it looks like rain, but we are going to proceed our review.
Due to the torky engine and good suspension it is even possible to move without any road.
You seat on a bike quite close to the ground so it is easy to control the movement on a
low speed by legs.
Besides bike is not very heavy – less then hundred kilos.
And speaking about footsteps.
On one hand they are wide and it is comfortable to stay on them.
But on the other hand it is better not move in a rut on this bike.
It is easy to get stuck in a rut due to the wide footstep.
But the ground clearance is pretty large it is 320mm, so it should be quite deep rut where
the bike can get stuck.
This bike has a rear drive, so it is not designed to move in a hard offroading.
It is for sand and snow, cross country roads and so on.
But it is interesting for us to find out its limits!
And this real swamp is the best location for that purpose!
Lets try it.
It could have been worse.
Even with a rear drive the bike is moving in swamp.
But we should remember that the variator is afraid of water, so we can’t go very deep.
And when I finally got stuck I managed then to escape from this trap on my own, thanks
to the bike that is now very heavy.
Finally this test ended not very successful.
The chain and a sprocket got clogged with swamp mud and the chain came off.
But its not fatal, we cleaned the gears and were able to proceed our trip.
I think we have a decent result of this test for a rear wheel drive bike.
By the way it is possible to ride on a bike with a passanger!
We didn’t shoot it, but we moved on a bike together with my college all the way while
shooting this video.
And now it is high time to speak about the prices.
And the price is quite affordable I should say – it is only about 1000 dollars.
Guys please post your comments what you think about this bike and if it is worth its money?
