Hi
guys as usually its me just a voice over and you are watching review machines!
It is early spring already and we have a start of bicycle season now, and today we have so
curious bike to review!
Actually the bike Is pretty standard, but it is equipped with a very interesting kit,
that has several huge advantages.
The first one!
This kit is suitable almost for any adult bike.
The second, for this kit you can take any engine from a gas trimmer and then if necessary
to you can put it back.
And the third with this kit bikes transmission still works with shifting all gears.
And finally with this kit the bike is still quite light, and it is still possible to pedal
it.
As a matter of fact all these features are just a theory and today we are going to test
them in practice to find out if it is kit is really good enough.
Well its time to begin, lets do it!
Well lets look at the construction.
As I said we have a standard adult bike with a standard frame.
Now you see the kit mounted on the frame.
At the front part of the kit there is an engine, it is possible to use any engine from a grass
trimmer.
We took the simplest and cheapest motor 1 hp, 2 stroke, 25 cc.
Frankly speaking it is definitely not the best engine for this kit.
And now you see the centrifugal clutch, than starts working approximately at 3000 rpm.
There is a belt drive with three belts.
The first one is external, the next belt is inside the frame of the kit.
And finally the drive goes by a chain to the overrunning clutch, that unites both engine
and pedal momentum.
The rear wheel is driven by the second chain through a standard bikes transmission.
The body of the kit is made of a plywood, but I think it would be better to make it
of something like carbon.
There are two locks, that fix the kit to the frame of the bike.
To control the engine there is a throttle on the handlebar and a button to stop it.
As I said one of the features of this kit is its lightweight, so lets weigh it.
The result is 23 kilos, and I think it’s a great result for a motorized bike taking
into account that the weight of the bike is about 16 kilos.
Now lets see how all this gear works when its moving.
We see the pedal drive working as usually, so we can use the pedals with this kit.
Now lets try to start the engine.
Well and the most interesting, lets see if the transmission works.
It seems that it works pretty good.
So I think it is high time to move to the practice.
And I am looking forward to share with you my very first impressions guys!
And I think the idea of this project definitely works.
It is so fun to ride quite a standard bike, and yes it feels absolutely like a regular
bike, may be just a bit heavier.
But the most curious you can at any time start the engine and its 1 horse power will do all
the job instead of you.
My weight is 86 kilos, and I should say this tiny motor surprisingly is able to move my
weight without my help with pedals.
But the huge advantage of this project is the working transmission.
It does a lot of good.
For example when I am riding on a forest road, I put the lowest gear and it provides good
torque on a rough terrain.
As you can see on a low gear it is possible to start moving without pedals.
On the other hand we still have a regular bike and you can switch to the pedals at any
moment.
But we should take into account that now it is approximately 10% harder to pedal than
on a regular bike without kit.
Then I should mention that it is possible to use an engine and pedals simultaneously
helping each other, it’s a kind an assist mode like on electric bikes.
Now lets move to the asphalt to see what this bike can show us there.
First of all meet the author of the project its Pasha.
The main idea of his project is to make a kit that would be useful for those cyclists
who love distant travels on their bikes.
Electric bikes have numerous advantages of course, but they still have one drawback – it’s
a limited range.
So they may not be suitable for distant rides.
But in our case…
For example we have been pedaling for a long time and got quite tired.
But we won’t stop for having a rest.
Instead of that we just start our engine and keep on moving!
Now lets see how the shifting of the gears works on asphalt.
It works perfectly!
And now it is interesting to find out the maximum speed without pedals on a high gear.
As we can see it is about 40 kmh.
To my mind it’s a decent result taking into account that our kit is equipped with the
weakest engine, and it is possible to use here much more powerful motors.
Pasha is 10 kilos lighter than me and he literally flies on his bike through the forest.As to
me Generally speaking I liked the idea of this kit.
But I would rather change some things.
Firstly frankly speaking plywood is not the best material for a body of this kit.
It would be much better to make it of a carbon for example.
Then it is defiantely better to use here more powerful engine for higher speed and heavier
riders.
I think some 2 hp 4 stroke engine would fit here beautifully.
Besides it would work much quieter.
And finally it is easier to start 4 stroke motors.
Cause sometimes it is not so simple here.
For all that this kit is definitely worth of our attention, cause it can turn almost
any regular bike into a motorized bike, still with working pedals and transmission.
You can take any engine, its very lightweight – all these features make this project quite
a curious solution.
But what about the price?
How much can this kit cost?
Unfortunately, this kit now is not serial production.
The author now is looking for investors.
If it sometime go to serial production its price will be about 400 dollars.
But it is not clear for now if this kit is interesting enough to be serial produced.
What do you think guys, it its worth it or no?
Please post your comments.
Well besides there is an idea to make a video comparison between this motorized bike and
some electric bike.
Would you like to see such a video?
And now lets call it a day!
Thanks for having a ride with us!
