RnD-Africa: Super Electric Bikes made in Ghana

  • 0:00 - 0:02
    Do you see where I am seated?
  • 0:02 - 0:07
    This is what we bring you on this
    episode of R&D Africa on AAU TV.
  • 0:07 - 0:12
    The spotlight has been put on the young
    Lawrence Adjei, who has been able to make
  • 0:12 - 0:16
    this electronic motorcycle
    from dead laptop batteries.
  • 0:16 - 0:18
    Stay tuned.
    We'll bring you more.
  • 0:26 - 0:31
    In an era where environmental protection,
    fitness and green travel
  • 0:31 - 0:34
    are increasingly being valued and
    practiced by people,
  • 0:34 - 0:37
    what comes to mind when
    transportation that allows you
  • 0:37 - 0:39
    to avoid road traffic congestion,
  • 0:40 - 0:42
    be green and environmentally
    friendly is mentioned.
  • 0:46 - 0:50
    Electric bicycles or e-bikes
    are equipped with electric devices
  • 0:50 - 0:53
    activated to assist
    or replace peddling.
  • 0:53 - 0:55
    They provide a number of benefits.
  • 0:55 - 1:00
    They are fuel efficient, faster,
    reduces traffic congestion
  • 1:00 - 1:02
    and are mostly non-pollutant.
  • 1:04 - 1:07
    Inventors mainly rely on
    batteries such as lithium-ion,
  • 1:08 - 1:09
    nickel-cadmium,
  • 1:09 - 1:11
    lithium-cobalt batteries
  • 1:11 - 1:12
    lead acid,
  • 1:12 - 1:14
    nickel-metal hydrate,
  • 1:14 - 1:15
    lithium-magnanese
  • 1:15 - 1:18
    and lithium-ion polymer
    batteries as the accessories.
  • 1:19 - 1:22
    Interestingly, a young
    Ghanaian, Lawrence Adjei
  • 1:22 - 1:26
    has added to the innovations
    in the electric bike industry.
  • 1:26 - 1:29
    He uses sports laptop
    batteries, which he purchases
  • 1:29 - 1:34
    from scrap yards and computer
    shops in Accra to make his unique e-bikes.
  • 1:35 - 1:38
    He is known to be the first
    Ghanian to make electric bicylces
  • 1:38 - 1:42
    from sports laptop batteries
    and he is self-taught.
  • 1:45 - 1:50
    I stay close to Lawrence and
    I happen to be his co-helper.
  • 1:50 - 1:52
    This is not my first time riding.
  • 1:52 - 1:54
    I've been riding for two years now.
  • 1:54 - 1:56
    The experience is different.
  • 1:57 - 2:00
    Different. I can't even compare
    because riding a normal bicycle...
  • 2:00 - 2:01
    is full of pain.
  • 2:01 - 2:06
    And then you actually admire the
    kind of kilometers you need to go.
  • 2:06 - 2:10
    So this is really different compared
    to the ones I have ever used.
  • 2:10 - 2:14
    This has three gears
    and then the others don't.
  • 2:14 - 2:21
    It has a brake which charges the battery
    back when applying, the others don't have.
  • 2:21 - 2:25
    It has a USB spot which
    can charge your phone
  • 2:25 - 2:26
    or use a USB light.
  • 2:27 - 2:28
    Which others don't have.
  • 2:29 - 2:32
    And then it also has a bell,
    the others didn't have a bell.
  • 2:33 - 2:37
    And then the brakes are instant stop.
  • 2:37 - 2:38
    They stop instantly.
  • 2:38 - 2:41
    Next. Coming to the battery,
  • 2:41 - 2:43
    it has a large capacity,
    which you can even
  • 2:43 - 2:46
    give a house a light.
  • 2:49 - 2:53
    This is where Mr. Lawrence
    AJ makes all the inventions.
  • 2:53 - 2:56
    This is where the
    creation of electric bicycles
  • 2:56 - 2:59
    made out of dead
    laptop batteries happens and
  • 2:59 - 3:01
    I'm currently here with Mr. Lawrence.
  • 3:02 - 3:04
    Take us through
    the process involved in the
  • 3:04 - 3:07
    usage of these batteries
    to make the electric bicycle.
  • 3:07 - 3:10
    So you have the batteries here.
  • 3:10 - 3:12
    So, you just crack them like this.
  • 3:13 - 3:15
    You sometimes bend it or...
  • 3:16 - 3:17
    or use a plier.
  • 3:17 - 3:18
    Okay
  • 3:22 - 3:24
    You can see that we
    don't use all the cells.
  • 3:25 - 3:26
    This one is here, the bud.
  • 3:27 - 3:29
    - Okay
    - You can't use this one, so
  • 3:29 - 3:30
    You find a different one.
  • 3:31 - 3:32
    Try another one.
  • 3:39 - 3:40
    Same.
  • 3:40 - 3:43
    This one is okay, So you take
    like the motherboard
  • 3:43 - 3:44
    - of the battery. So...
    - Okay
  • 3:44 - 3:45
    So taking them off
  • 3:46 - 3:49
    [Inaudible]
  • 3:55 - 3:57
    Then take the cells out like this.
  • 3:57 - 3:59
    Okay
  • 4:00 - 4:03
    So in total, how many
    of these do you need?
  • 4:03 - 4:04
    I need a lot, but
  • 4:04 - 4:06
    I only have 6 batteries here.
  • 4:06 - 4:07
    Okay
  • 4:07 - 4:12
    Then you test it with the voltmeter to
    see whether they have some voltage inside.
  • 4:12 - 4:15
    What is the average voltage
    you need in the batteries?
  • 4:15 - 4:18
    I think like 2.5 volts.
    2.5 volts is fine.
  • 4:18 - 4:19
    - Okay
    - This one is good
  • 4:19 - 4:21
    - Okay
    - So then we come here
  • 4:21 - 4:23
    and test with this machine here.
  • 4:23 - 4:25
    This one is called Opus.
  • 4:25 - 4:27
    This one does the capacity testing.
  • 4:27 - 4:30
    - Okay
    - So you place the cells inside like this.
  • 4:30 - 4:32
    So you can see it charging, so...
  • 4:32 - 4:35
    It will charge the batteries
    for like two hours
  • 4:35 - 4:36
    - Okay
    - Only two hours
  • 4:36 - 4:43
    After that, the machine will discharge
    the battery and give you the capacity.
  • 4:43 - 4:45
    - Okay
    - Then we take it off.
  • 4:45 - 4:48
    Then we write the capacity on it.
  • 4:52 - 4:54
    Comparing the other things too.
  • 4:54 - 4:58
    It has a Bluetooth device in it,
    which you can use to program your phone.
  • 4:58 - 5:02
    So imagine I'm going on a
    high speed, you don't like drop
  • 5:02 - 5:05
    it on your phone and then
    it will drop automatically.
  • 5:05 - 5:07
    It doesn't matter the acceleration.
  • 5:07 - 5:10
    For the other bikes,
    they don't have reverse.
  • 5:10 - 5:12
    You just need to push them back like this.
  • 5:12 - 5:14
    But then this one has a reverse.
  • 5:14 - 5:15
    So there is no need.
  • 5:15 - 5:19
    When the key is on, you just push
    the button and then you accelerate.
  • 5:19 - 5:22
    It doesn't accelerate
    like you're on a top
  • 5:22 - 5:27
    speed, but it's very strong
    and it takes you back slowly.
  • 5:27 - 5:31
    No matter what obstacle,
    it will take you back slowly.
  • 5:31 - 5:34
    I think this is all about.
  • 5:34 - 5:37
    For the other bikes,
    we do have front shocks.
  • 5:37 - 5:42
    And then, front shocks, talking
    about this one, this is filled with air.
  • 5:42 - 5:44
    It's different from the other one.
  • 5:44 - 5:47
    The other one is a
    little air, but more of oil.
  • 5:47 - 5:51
    But then this one is
    air, so you stop instantly.
  • 5:51 - 5:53
    And you see for the back too.
  • 5:53 - 5:55
    It's also different for the back.
  • 5:55 - 5:57
    Actually, the other
    bikes, when you are riding
  • 5:57 - 6:01
    and then you pass through a pothole,
    you feel some pains in your waist.
  • 6:01 - 6:02
    But then this one, you don't feel.
  • 6:02 - 6:05
    You just go through and then you're okay.
  • 6:05 - 6:08
    So anytime you are
    riding this bike, it makes
  • 6:08 - 6:11
    you feel like go more,
    go more, go more.
  • 6:11 - 6:15
    It's really nice to have
    one of these bikes.
  • 6:19 - 6:21
    My name is AJ Lawrence.
  • 6:21 - 6:23
    I live in Kaswa in the
    central region of Ghana.
  • 6:23 - 6:26
    At age 11, when Lawrence
    discovered his talent,
  • 6:26 - 6:31
    he acquainted himself with playing with
    electronic gadgets such as computers.
  • 6:31 - 6:34
    A year after his
    interest in that field grew,
  • 6:34 - 6:37
    he picked up the mantle
    of repairing bicycles.
  • 6:37 - 6:40
    Until date, he still
    repairs a number of bikes.
  • 6:40 - 6:44
    So far, Lawrence has made and
    sold four e-bikes made by himself.
  • 6:44 - 6:50
    Current bicycle presents upgraded features
    from the ones he has made in the past.
  • 6:50 - 6:52
    Professor Jay looks
    forward to contacting
  • 6:52 - 6:54
    universities for
    collaborations and partnerships
  • 6:54 - 6:59
    in order to take his innovative
    ideas to the next level.
  • 6:59 - 7:04
    He has dreams of using solar to propel his
    bikes in future, but needs collaborations
  • 7:04 - 7:07
    and partnerships with
    universities and technical
  • 7:07 - 7:10
    institutions to scale up
    production from prototype
  • 7:10 - 7:12
    to commercialization.
  • 7:12 - 7:15
    In such partnerships,
    he seeks to train technical
  • 7:15 - 7:18
    students to improve their
    knowledge on electronics.
  • 7:22 - 7:24
    I have a question.
  • 7:24 - 7:27
    So this experiment only works
    when you are using the spot
  • 7:27 - 7:29
    or dead laptop batteries or
    you can use brand new ones.
  • 7:29 - 7:31
    You can use brand new ones for sure.
  • 7:31 - 7:32
    Okay
  • 7:32 - 7:33
    Okay.
  • 7:33 - 7:36
    So now on charging the
    bicycle, how is it charged?
  • 7:36 - 7:39
    It's charged with this charger here.
  • 7:39 - 7:41
    This one is a custom built charger.
  • 7:41 - 7:43
    It's not like the normal charger.
  • 7:43 - 7:45
    It will take like maybe 12
    hours, 6 hours to charge.
  • 7:45 - 7:46
    Ok
  • 7:46 - 7:48
    This one does around like 3 hours.
  • 7:48 - 7:49
    Okay.
  • 7:51 - 7:52
    And did you make it yourself?
  • 7:52 - 7:53
    Yes.
  • 7:53 - 7:55
    I bought the parts.
  • 7:55 - 7:56
    Okay.
  • 7:56 - 8:00
    So with the parts that you
    worked on, can you run us briefly
  • 8:00 - 8:02
    through the process, how
    you came to that conclusion?
  • 8:02 - 8:05
    For this one, it's a server power supply.
  • 8:05 - 8:06
    Okay.
  • 8:06 - 8:08
    It's in light service.
  • 8:08 - 8:11
    You know, light service, they
    have a lot of computers inside.
  • 8:11 - 8:13
    So they have very good processors.
  • 8:14 - 8:18
    And this one here is called
    step up converter
  • 8:18 - 8:20
    Okay
  • 8:20 - 8:22
    So if you take 3 volts and pass
  • 8:22 - 8:25
    Then it converts you to 84 volts
  • 8:25 - 8:27
    Okay
  • 8:27 - 8:30
    Now on the features of your bike
  • 8:30 - 8:36
    What features does your bicycle have that
    ones in the market do not have?
  • 8:36 - 8:38
    This one has everything programmable.
  • 8:38 - 8:42
    You can choose the program that
    work on your phone.
  • 8:42 - 8:44
    Okay, okay.
  • 8:45 - 8:48
    It also has like phone charging
    to charge your phones.
  • 8:49 - 8:52
    It also has Evergine brake.
  • 8:52 - 8:56
    That means when you hit a break
    it charges a bike
  • 8:56 - 9:02
    So like you don't try to use like
    Venoma Veperseto stop when you hit a break
  • 9:02 - 9:05
    It does it instantly in a break
  • 9:07 - 9:10
    How do you respond to support
    this project?
  • 9:10 - 9:12
    How have you been doing it?
  • 9:12 - 9:13
    Believing in myself.
  • 9:17 - 9:20
    Okay, so my challenges when
    I was working on a bike
  • 9:20 - 9:23
    was, at first I didn't have a welding
    machine and a spray machine.
  • 9:23 - 9:26
    So I take it to welders and sprayers.
  • 9:26 - 9:28
    But they take your money
    and they wouldn't do the work.
  • 9:28 - 9:32
    I decided to buy the welding
    machine and the spray machine.
  • 9:32 - 9:35
    Then started learning
    welding and spraying myself.
  • 9:35 - 9:39
    So it took me like a
    week or two to learn all.
  • 9:39 - 9:42
    Sometimes my friends
    always discouraging me
  • 9:42 - 9:44
    that it won't work and
    you're always wasting
  • 9:44 - 9:47
    your time on this thing, go
    find a job and get some money.
  • 9:47 - 9:50
    My challenges about
    financing is like sometimes
  • 9:50 - 9:53
    I don't really get the money
    in bulk to buy the parts.
  • 9:53 - 9:55
    So like I'll buy one
    maybe this month, the
  • 9:55 - 9:57
    next month I'll buy
    the one and they all like
  • 9:57 - 10:00
    take shipments, which
    like is a lot of cost.
  • 10:00 - 10:05
    So when I get like funds to buy them
    in bulk, I think it will help the process.
  • 10:09 - 10:12
    Lawrence intends to set
    up a permanent working
  • 10:12 - 10:15
    place for himself,
    create employment for
  • 10:15 - 10:19
    interested inventors
    and give back to society.
  • 10:19 - 10:22
    Lawrence Adjei is not
    only putting the African
  • 10:22 - 10:25
    continent on the map,
    he has also distinguished.
  • 10:25 - 10:28
    himself as one of the
    many undiscovered great
  • 10:28 - 10:32
    minds in Africa who can
    do more with a little push.
  • 10:32 - 10:36
    This is where we end
    this interesting, revealing
  • 10:36 - 10:39
    and educative episode
    of R&D Africa on AAU TV.
  • 10:39 - 10:42
    Don't forget that next time the
    spotlight could be put on you.
  • 10:42 - 10:45
    So if you have any
    innovations or inventions
  • 10:45 - 10:49
    out there, contact AAU TV
    and we'll be at your doorstep.

    My name is Maame Ekua Otuakoa Nyame.
  • 10:57 - 10:59
    Until next time, it's a wrap!
  • 10:59 - 11:14
