1
00:00:00,000 --> 00:00:02,000
Do you see where I am seated?

2
00:00:02,001 --> 00:00:07,000
This is what we bring you on this
episode of R&D Africa on AAU TV.

3
00:00:07,001 --> 00:00:12,000
The spotlight has been put on the young
Lawrence Adjei, who has been able to make

4
00:00:12,001 --> 00:00:16,260
this electronic motorcycle
from dead laptop batteries.

5
00:00:16,260 --> 00:00:17,890
Stay tuned.
We'll bring you more.

6
00:00:26,050 --> 00:00:30,664
In an era where environmental protection,
fitness and green travel

7
00:00:30,664 --> 00:00:34,092
are increasingly being valued and
practiced by people,

8
00:00:34,402 --> 00:00:37,000
what comes to mind when
transportation that allows you

9
00:00:37,000 --> 00:00:38,614
to avoid road traffic congestion,

10
00:00:39,614 --> 00:00:42,000
be green and environmentally
friendly is mentioned.

11
00:00:45,883 --> 00:00:49,930
Electric bicycles or e-bikes
are equipped with electric devices

12
00:00:49,930 --> 00:00:52,509
activated to assist
or replace peddling.

13
00:00:52,985 --> 00:00:55,000
They provide a number of benefits.

14
00:00:55,425 --> 00:00:59,522
They are fuel efficient, faster, 
reduces traffic congestion

15
00:00:59,522 --> 00:01:01,850
and are mostly non-pollutant.

16
00:01:04,020 --> 00:01:07,439
Inventors mainly rely on 
batteries such as lithium-ion,

17
00:01:07,641 --> 00:01:08,841
nickel-cadmium,

18
00:01:09,231 --> 00:01:10,852
lithium-cobalt batteries

19
00:01:10,921 --> 00:01:11,921
lead acid,

20
00:01:12,081 --> 00:01:13,801
nickel-metal hydrate,

21
00:01:13,801 --> 00:01:14,851
lithium-manganese

22
00:01:14,851 --> 00:01:18,000
and lithium-ion polymer
batteries as the accessories.

23
00:01:18,845 --> 00:01:22,068
Interestingly, a young
Ghanaian, Lawrence Adjei

24
00:01:22,068 --> 00:01:26,030
has added to the innovations
in the electric bike industry.

25
00:01:26,030 --> 00:01:29,075
He uses sports laptop
batteries, which he purchases

26
00:01:29,075 --> 00:01:34,430
from scrap yards and computer
shops in Accra to make his unique e-bikes.

27
00:01:34,800 --> 00:01:38,182
He is known to be the first 
Ghanaian to make electric bicycles

28
00:01:38,182 --> 00:01:42,000
from sports laptop batteries
and he is self-taught.

29
00:01:45,471 --> 00:01:50,088
I stay close to Lawrence and
I happen to be this co-helper.

30
00:01:50,088 --> 00:01:52,222
This is not my first time riding.

31
00:01:52,472 --> 00:01:54,460
I've been riding for two years now.

32
00:01:54,460 --> 00:01:56,463
The experience is different.

33
00:01:56,621 --> 00:02:00,202
Different. I can't even compare
because riding a normal bicycle...

34
00:02:00,202 --> 00:02:01,370
is full of pain.

35
00:02:01,370 --> 00:02:05,740
And then you actually admire the 
kind of kilometers you need to go.

36
00:02:06,001 --> 00:02:10,339
So this is really different compared
to the ones I have ever used.

37
00:02:10,339 --> 00:02:13,700
This has three gears
and then the others don't.

38
00:02:14,280 --> 00:02:20,543
It has a brake which charges the battery
back when applying, the others don't have.

39
00:02:21,001 --> 00:02:24,537
It has a USB spot which
can charge your phone

40
00:02:24,537 --> 00:02:26,250
or use a USB light.

41
00:02:26,541 --> 00:02:28,254
Which the others don't have.

42
00:02:28,811 --> 00:02:32,062
And then it also has a bell,
the others didn't have a bell.

43
00:02:32,962 --> 00:02:36,634
And then the brakes are instant stop.

44
00:02:36,794 --> 00:02:38,010
They stop instantly.

45
00:02:38,370 --> 00:02:40,525
Next. Coming to the battery,

46
00:02:40,525 --> 00:02:42,944
it has a large capacity,
which you can even

47
00:02:43,204 --> 00:02:45,586
give a house a light.

48
00:02:49,275 --> 00:02:52,640
This is where Mr. Lawrence
AJ makes all the inventions.

49
00:02:52,640 --> 00:02:55,647
This is where the
creation of electric bicycles

50
00:02:55,647 --> 00:02:58,920
made out of dead
laptop batteries happens and

51
00:02:58,920 --> 00:03:01,000
I'm currently here with Mr. Lawrence.

52
00:03:01,601 --> 00:03:03,656
Take us through 
the process involved in the

53
00:03:03,656 --> 00:03:07,000
usage of these batteries 
to make the electric bicycle.

54
00:03:07,481 --> 00:03:09,640
So you have the batteries here.

55
00:03:09,993 --> 00:03:11,986
So, you just crack them like this.

56
00:03:12,511 --> 00:03:15,121
You sometimes bend it or...

57
00:03:15,891 --> 00:03:16,891
or use a plier.

58
00:03:17,247 --> 00:03:18,267
Okay

59
00:03:21,533 --> 00:03:24,500
You can see that we
don't use all the cells.

60
00:03:24,551 --> 00:03:26,054
This one is here, the bud.

61
00:03:26,784 --> 00:03:28,870
-Okay
-You can't use this one, so

62
00:03:28,870 --> 00:03:30,063
You find a different one.

63
00:03:30,654 --> 00:03:31,753
Try another one.

64
00:03:38,610 --> 00:03:39,639
Same.

65
00:03:39,639 --> 00:03:42,665
This one is okay. So you take 
like the motherboard

66
00:03:42,665 --> 00:03:44,180
- of the battery. So...
- Okay

67
00:03:44,439 --> 00:03:45,439
So taking them off

68
00:03:46,058 --> 00:03:48,828
[Inaudible]

69
00:03:54,638 --> 00:03:56,965
Then take the cells out like this.

70
00:03:57,463 --> 00:03:58,503
Okay

71
00:04:00,391 --> 00:04:02,780
So in total, how many 
of these do you need?

72
00:04:03,001 --> 00:04:04,260
I need a lot, but

73
00:04:04,260 --> 00:04:05,991
I only have 6 batteries here.

74
00:04:05,991 --> 00:04:07,001
Okay

75
00:04:07,001 --> 00:04:12,000
Then you test it with the voltmeter to
see whether they have some voltage inside.

76
00:04:12,001 --> 00:04:15,000
What is the average voltage
you need in the batteries?

77
00:04:15,001 --> 00:04:17,588
I think like 2.5 volts.
2.5 volts is fine.

78
00:04:17,588 --> 00:04:19,131
- Okay
- This one is good

79
00:04:19,131 --> 00:04:20,968
- Okay
- So then we come here

80
00:04:20,968 --> 00:04:22,840
and test with this machine here.

81
00:04:22,840 --> 00:04:24,759
This one is called Opus.

82
00:04:24,759 --> 00:04:27,096
This one does the capacity testing.

83
00:04:27,096 --> 00:04:30,000
- Okay
- So you place the cells inside like this.

84
00:04:30,001 --> 00:04:32,425
So you can see it charging, so...

85
00:04:32,425 --> 00:04:34,940
It will charge the batteries
for like two hours

86
00:04:34,940 --> 00:04:36,470
- Okay
- Only two hours

87
00:04:36,470 --> 00:04:43,000
After that, the machine will discharge
the battery and give you the capacity.

88
00:04:43,159 --> 00:04:44,970
-Okay
-Then we take it off.

89
00:04:44,970 --> 00:04:48,360
Then we write the capacity on it.

90
00:04:52,001 --> 00:04:53,951
Comparing the other things too

91
00:04:53,951 --> 00:04:58,000
It has a Bluetooth device in it, 
which you can use to program your phone.

92
00:04:58,270 --> 00:05:02,309
So imagine I'm going on a
high speed, you don't like drop

93
00:05:02,309 --> 00:05:05,000
it on your phone and then
it will drop automatically.

94
00:05:05,001 --> 00:05:07,000
It doesn't matter the acceleration.

95
00:05:07,001 --> 00:05:10,000
For the other bikes,
they don't have reverse.

96
00:05:10,001 --> 00:05:12,000
You just need to push them back like this.

97
00:05:12,001 --> 00:05:13,778
But then this one has a reverse.

98
00:05:13,778 --> 00:05:15,000
So there is no need.

99
00:05:15,001 --> 00:05:19,000
When the key is on, you just push
the button and then you accelerate.

100
00:05:19,001 --> 00:05:21,919
It doesn't accelerate
like you're on a top

101
00:05:21,931 --> 00:05:27,000
speed, but it's very strong
and it takes you back slowly.

102
00:05:27,250 --> 00:05:31,000
No matter what obstacle,
it will take you back slowly.

103
00:05:31,001 --> 00:05:34,000
I think this is all about.

104
00:05:34,001 --> 00:05:37,000
For the other bikes,
we do have front shocks.

105
00:05:37,100 --> 00:05:41,800
And then, front shocks, talking
about this one, this is filled with air.

106
00:05:41,800 --> 00:05:43,570
It's different from the other one.

107
00:05:43,570 --> 00:05:47,000
The other one is a
little air, but more of oil.

108
00:05:47,001 --> 00:05:51,000
But then this one is
air, so you stop instantly.

109
00:05:51,001 --> 00:05:53,000
And you see for the back too.

110
00:05:53,001 --> 00:05:55,000
It's also different for the back.

111
00:05:55,150 --> 00:05:57,347
Actually, the other
bikes, when you are riding

112
00:05:57,347 --> 00:06:00,721
and then you pass through a pothole,
you feel some pains in your waist.

113
00:06:00,721 --> 00:06:02,420
But then this one, you don't feel.

114
00:06:02,420 --> 00:06:05,000
You just go through and then you're okay.

115
00:06:05,001 --> 00:06:08,165
So anytime you are
riding this bike, it makes

116
00:06:08,177 --> 00:06:11,000
you feel like go more,
go more, go more.

117
00:06:11,150 --> 00:06:14,700
It's really nice to have
one of these bikes.

118
00:06:18,860 --> 00:06:20,625
My name is AJ Lawrence.

119
00:06:20,650 --> 00:06:23,000
I live in Kaswa in the
central region of Ghana.

120
00:06:23,075 --> 00:06:25,934
At age 11, when Lawrence
discovered his talent,

121
00:06:25,946 --> 00:06:31,000
he acquainted himself with playing with
electronic gadgets such as computers.

122
00:06:31,425 --> 00:06:34,170
A year after his
interest in that field grew,

123
00:06:34,182 --> 00:06:37,000
he picked up the mantle
of repairing bicycles.

124
00:06:37,001 --> 00:06:40,000
Until date, he still
repairs a number of bikes.

125
00:06:40,100 --> 00:06:44,000
So far, Lawrence has made and
sold four e-bikes made by himself.

126
00:06:44,125 --> 00:06:49,810
Current bicycle presents upgraded features
from the ones he has made in the past.

127
00:06:49,810 --> 00:06:51,831
Professor Jay looks
forward to contacting

128
00:06:51,831 --> 00:06:54,220
universities for
collaborations and partnerships

129
00:06:54,250 --> 00:06:59,000
in order to take his innovative
ideas to the next level.

130
00:06:59,001 --> 00:07:04,000
He has dreams of using solar to propel his
bikes in future, but needs collaborations

131
00:07:04,001 --> 00:07:06,927
and partnerships with
universities and technical

132
00:07:06,939 --> 00:07:10,000
institutions to scale up
production from prototype

133
00:07:10,450 --> 00:07:12,000
to commercialization.

134
00:07:12,150 --> 00:07:15,005
In such partnerships,
he seeks to train technical

135
00:07:15,017 --> 00:07:18,000
students to improve their
knowledge on electronics.

136
00:07:21,900 --> 00:07:23,761
I have a question.

137
00:07:23,786 --> 00:07:26,767
So this experiment only works
when you are using the spot

138
00:07:26,767 --> 00:07:29,380
or dead laptop batteries or
you can use brand new ones.

139
00:07:29,380 --> 00:07:31,160
You can use brand new ones for sure.

140
00:07:31,160 --> 00:07:32,190
Okay

141
00:07:32,190 --> 00:07:33,230
Okay.

142
00:07:33,230 --> 00:07:36,000
So now on charging the
bicycle, how is it charged?

143
00:07:36,001 --> 00:07:39,184
It's charged with this charger here.

144
00:07:39,184 --> 00:07:40,952
This one is a custom built charger.

145
00:07:40,952 --> 00:07:42,540
It's not like the normal charger.

146
00:07:42,540 --> 00:07:44,980
It will take like maybe 12
hours, 6 hours to charge.

147
00:07:44,980 --> 00:07:46,010
Ok

148
00:07:46,010 --> 00:07:47,689
This one does around like 3 hours.

149
00:07:47,689 --> 00:07:49,171
Okay.

150
00:07:50,801 --> 00:07:52,270
And did you make it yourself?

151
00:07:52,270 --> 00:07:53,359
Yes.

152
00:07:53,359 --> 00:07:54,740
I bought the parts.

153
00:07:54,740 --> 00:07:55,810
Okay.

154
00:07:56,081 --> 00:07:59,700
So with the parts that you
worked on, can you run us briefly

155
00:07:59,701 --> 00:08:02,200
through the process, how
you came to that conclusion?

156
00:08:02,301 --> 00:08:04,800
For this one, it's a server power supply.

157
00:08:04,801 --> 00:08:05,820
Okay.

158
00:08:05,820 --> 00:08:07,500
It's in light service.

159
00:08:07,601 --> 00:08:11,326
You know, light service, they
have a lot of computers inside.

160
00:08:11,450 --> 00:08:13,395
So they have very good processor.

161
00:08:14,185 --> 00:08:18,319
And this one here is called 
step up converter

162
00:08:18,319 --> 00:08:19,578
Okay

163
00:08:19,578 --> 00:08:22,318
So if you take 3 volts and pass

164
00:08:22,342 --> 00:08:25,175
Then it coverts you to 84 volts

165
00:08:25,199 --> 00:08:27,199
Okay

166
00:08:27,223 --> 00:08:29,841
Now on the features of your bike

167
00:08:29,841 --> 00:08:35,655
What features does your bicycle have that
ones in the market do not have?

168
00:08:35,679 --> 00:08:38,252
This one has everything programmable.

169
00:08:38,276 --> 00:08:41,822
You can choose the programm that 
work on your phone.

170
00:08:41,846 --> 00:08:43,846
Okay, okay.

171
00:08:45,016 --> 00:08:48,289
It also has like phone charging 
to charge your phones.

172
00:08:48,992 --> 00:08:52,252
It also has Evergine brake.

173
00:08:52,276 --> 00:08:56,076
That means when you hit a break
it charges a bike

174
00:08:56,127 --> 00:09:02,173
So like you don't try to use like 
Venoma Veperseto stop when you hit a break

175
00:09:02,197 --> 00:09:04,630
It does it instantly in a break

176
00:09:06,766 --> 00:09:10,458
How do you respond to support 
this project?

177
00:09:10,458 --> 00:09:11,866
How have you been doing it?

178
00:09:11,891 --> 00:09:13,170
Believing in myself.

179
00:09:16,943 --> 00:09:19,843
Okay, so my challenges when
I was working on a bike

180
00:09:19,868 --> 00:09:23,000
was, at first I didn't have a welding
machine and a spray machine.

181
00:09:23,001 --> 00:09:25,710
So I take it to welders and sprayers.

182
00:09:25,710 --> 00:09:28,330
But they take your money
and they wouldn't do the work.

183
00:09:28,330 --> 00:09:32,000
I decided to buy the welding
machine and the spray machine.

184
00:09:32,100 --> 00:09:35,000
Then started learning
welding and spraying myself.

185
00:09:35,001 --> 00:09:39,380
So it took me like a
week or two to learn all.

186
00:09:39,380 --> 00:09:41,576
Sometimes my friends
always discouraging me

187
00:09:41,576 --> 00:09:44,000
that it won't work and
you're always wasting

188
00:09:44,001 --> 00:09:47,000
your time on this thing, go
find a job and get some money.

189
00:09:47,001 --> 00:09:49,600
My challenges about
financing is like sometimes

190
00:09:49,612 --> 00:09:52,570
I don't really get the money
in bulk to buy the parts.

191
00:09:52,570 --> 00:09:54,650
So like I'll buy one
maybe this month, the

192
00:09:54,650 --> 00:09:57,000
next month I'll buy
the one and they all like

193
00:09:57,001 --> 00:10:00,000
take shipments, which
like is a lot of cost.

194
00:10:00,001 --> 00:10:05,000
So when I get like funds to buy them
in bulk, I think it will help the process.

195
00:10:09,000 --> 00:10:11,833
Lawrence intends to set
up a permanent working

196
00:10:11,845 --> 00:10:15,000
place for himself,

197
00:10:15,001 --> 00:10:19,000

and give back to society.

198
00:10:19,025 --> 00:10:21,937

minds in Africa who can
do more with a little push.
