-
Do you see where I am seated?
-
This is what we bring you on this
episode of R&D Africa on AAU TV.
-
The spotlight has been put on the young
Lawrence Adjei, who has been able to make
-
this electronic motorcycle
from dead laptop batteries.
-
Stay tuned.
We'll bring you more.
-
In an era where environmental protection,
fitness and green travel
-
are increasingly being valued and
practiced by people,
-
what comes to mind when
transportation that allows you
-
to avoid road traffic congestion,
-
be green and environmentally
friendly is mentioned.
-
Electric bicycles or e-bikes
are equipped with electric devices
-
activated to assist
or replace peddling.
-
They provide a number of benefits.
-
They are fuel efficient, faster,
reduces traffic congestion
-
and are mostly non-pollutant.
-
Inventors mainly rely on
batteries such as lithium-ion,
-
nickel-cadmium,
-
lithium-cobalt batteries
-
lead acid,
-
nickel-metal hydrate,
-
lithium-magnanese
-
and lithium-ion polymer
batteries as the accessories.
-
Interestingly, a young
Ghanaian, Lawrence Adjei
-
has added to the innovations
in the electric bike industry.
-
He uses sports laptop
batteries, which he purchases
-
from scrap yards and computer
shops in Accra to make his unique e-bikes.
-
He is known to be the first
Ghanian to make electric bicylces
-
from sports laptop batteries
and he is self-taught.
-
I stay close to Lawrence and
I happen to be his co-helper.
-
This is not my first time riding.
-
I've been riding for two years now.
-
The experience is different.
-
Different. I can't even compare
because riding a normal bicycle...
-
is full of pain.
-
And then you actually admire the
kind of kilometers you need to go.
-
So this is really different compared
to the ones I have ever used.
-
This has three gears
and then the others don't.
-
It has a brake which charges the battery
back when applying, the others don't have.
-
It has a USB spot which
can charge your phone
-
or use a USB light.
-
Which others don't have.
-
And then it also has a bell,
the others didn't have a bell.
-
And then the brakes are instant stop.
-
They stop instantly.
-
Next. Coming to the battery,
-
it has a large capacity,
which you can even
-
give a house a light.
-
This is where Mr. Lawrence
AJ makes all the inventions.
-
This is where the
creation of electric bicycles
-
made out of dead
laptop batteries happens and
-
I'm currently here with Mr. Lawrence.
-
Take us through
the process involved in the
-
usage of these batteries
to make the electric bicycle.
-
So you have the batteries here.
-
So, you just crack them like this.
-
You sometimes bend it or...
-
or use a plier.
-
Okay
-
You can see that we
don't use all the cells.
-
This one is here, the bud.
-
- Okay
- You can't use this one, so
-
You find a different one.
-
Try another one.
-
Same.
-
This one is okay, So you take
like the motherboard
-
- of the battery. So...
- Okay
-
So taking them off
-
[Inaudible]
-
Then take the cells out like this.
-
Okay
-
So in total, how many
of these do you need?
-
I need a lot, but
-
I only have 6 batteries here.
-
Okay
-
Then you test it with the voltmeter to
see whether they have some voltage inside.
-
What is the average voltage
you need in the batteries?
-
I think like 2.5 volts.
2.5 volts is fine.
-
- Okay
- This one is good
-
- Okay
- So then we come here
-
and test with this machine here.
-
This one is called Opus.
-
This one does the capacity testing.
-
- Okay
- So you place the cells inside like this.
-
So you can see it charging, so...
-
It will charge the batteries
for like two hours
-
- Okay
- Only two hours
-
After that, the machine will discharge
the battery and give you the capacity.
-
- Okay
- Then we take it off.
-
Then we write the capacity on it.
-
Comparing the other things too.
-
It has a Bluetooth device in it,
which you can use to program your phone.
-
So imagine I'm going on a
high speed, you don't like drop
-
it on your phone and then
it will drop automatically.
-
It doesn't matter the acceleration.
-
For the other bikes,
they don't have reverse.
-
You just need to push them back like this.
-
But then this one has a reverse.
-
So there is no need.
-
When the key is on, you just push
the button and then you accelerate.
-
It doesn't accelerate
like you're on a top
-
speed, but it's very strong
and it takes you back slowly.
-
No matter what obstacle,
it will take you back slowly.
-
I think this is all about.
-
For the other bikes,
we do have front shocks.
-
And then, front shocks, talking
about this one, this is filled with air.
-
It's different from the other one.
-
The other one is a
little air, but more of oil.
-
But then this one is
air, so you stop instantly.
-
And you see for the back too.
-
It's also different for the back.
-
Actually, the other
bikes, when you are riding
-
and then you pass through a pothole,
you feel some pains in your waist.
-
But then this one, you don't feel.
-
You just go through and then you're okay.
-
So anytime you are
riding this bike, it makes
-
you feel like go more,
go more, go more.
-
It's really nice to have
one of these bikes.
-
My name is AJ Lawrence.
-
I live in Kaswa in the
central region of Ghana.
-
At age 11, when Lawrence
discovered his talent,
-
he acquainted himself with playing with
electronic gadgets such as computers.
-
A year after his
interest in that field grew,
-
he picked up the mantle
of repairing bicycles.
-
Until date, he still
repairs a number of bikes.
-
So far, Lawrence has made and
sold four e-bikes made by himself.
-
Current bicycle presents upgraded features
from the ones he has made in the past.
-
Professor Jay looks
forward to contacting
-
universities for
collaborations and partnerships
-
in order to take his innovative
ideas to the next level.
-
He has dreams of using solar to propel his
bikes in future, but needs collaborations
-
and partnerships with
universities and technical
-
institutions to scale up
production from prototype
-
to commercialization.
-
In such partnerships,
he seeks to train technical
-
students to improve their
knowledge on electronics.
-
I have a question.
-
So this experiment only works
when you are using the spot
-
or dead laptop batteries or
you can use brand new ones.
-
You can use brand new ones for sure.
-
Okay
-
Okay.
-
So now on charging the
bicycle, how is it charged?
-
It's charged with this charger here.
-
This one is a custom built charger.
-
It's not like the normal charger.
-
It will take like maybe 12
hours, 6 hours to charge.
-
Ok
-
This one does around like 3 hours.
-
Okay.
-
And did you make it yourself?
-
Yes.
-
I bought the parts.
-
Okay.
-
So with the parts that you
worked on, can you run us briefly
-
through the process, how
you came to that conclusion?
-
For this one, it's a server power supply.
-
Okay.
-
It's in light service.
-
You know, light service, they
have a lot of computers inside.
-
So they have very good processors.
-
And this one here is called
step up converter
-
Okay
-
So if you take 3 volts and pass
-
Then it converts you to 84 volts
-
Okay
-
Now on the features of your bike
-
What features does your bicycle have that
ones in the market do not have?
-
This one has everything programmable.
-
You can choose the program that
work on your phone.
-
Okay, okay.
-
It also has like phone charging
to charge your phones.
-
It also has Evergine brake.
-
That means when you hit a break
it charges a bike
-
So like you don't try to use like
Venoma Veperseto stop when you hit a break
-
It does it instantly in a break
-
How do you respond to support
this project?
-
How have you been doing it?
-
Believing in myself.
-
Okay, so my challenges when
I was working on a bike
-
was, at first I didn't have a welding
machine and a spray machine.
-
So I take it to welders and sprayers.
-
But they take your money
and they wouldn't do the work.
-
I decided to buy the welding
machine and the spray machine.
-
Then started learning
welding and spraying myself.
-
So it took me like a
week or two to learn all.
-
Sometimes my friends
always discouraging me
-
that it won't work and
you're always wasting
-
your time on this thing, go
find a job and get some money.
-
My challenges about
financing is like sometimes
-
I don't really get the money
in bulk to buy the parts.
-
So like I'll buy one
maybe this month, the
-
next month I'll buy
the one and they all like
-
take shipments, which
like is a lot of cost.
-
So when I get like funds to buy them
in bulk, I think it will help the process.
-
Lawrence intends to set
up a permanent working
-
place for himself,
create employment for
-
interested inventors
and give back to society.
-
Lawrence Adjei is not
only putting the African
-
continent on the map,
he has also distinguished.
-
himself as one of the
many undiscovered great
-
minds in Africa who can
do more with a little push.
-
This is where we end
this interesting, revealing
-
and educative episode
of R&D Africa on AAU TV.
-
Don't forget that next time the
spotlight could be put on you.
