0:00:00.000,0:00:02.000 Do you see where I am seated? 0:00:02.001,0:00:07.000 This is what we bring you on this[br]episode of R&D Africa on AAU TV. 0:00:07.001,0:00:12.000 The spotlight has been put on the young[br]Lawrence Adjei, who has been able to make 0:00:12.001,0:00:16.260 this electronic motorcycle[br]from dead laptop batteries. 0:00:16.260,0:00:17.890 Stay tuned.[br]We'll bring you more. 0:00:26.050,0:00:30.664 In an era where environmental protection,[br]fitness and green travel 0:00:30.664,0:00:34.092 are increasingly being valued and[br]practiced by people, 0:00:34.402,0:00:37.000 what comes to mind when[br]transportation that allows you 0:00:37.000,0:00:38.614 to avoid road traffic congestion, 0:00:39.614,0:00:42.000 be green and environmentally[br]friendly is mentioned. 0:00:45.883,0:00:49.930 Electric bicycles or e-bikes[br]are equipped with electric devices 0:00:49.930,0:00:52.509 activated to assist[br]or replace peddling. 0:00:52.985,0:00:55.000 They provide a number of benefits. 0:00:55.425,0:00:59.522 They are fuel efficient, faster, [br]reduces traffic congestion 0:00:59.522,0:01:01.850 and are mostly non-pollutant. 0:01:04.020,0:01:07.439 Inventors mainly rely on [br]batteries such as lithium-ion, 0:01:07.641,0:01:08.841 nickel-cadmium, 0:01:09.231,0:01:10.852 lithium-cobalt batteries 0:01:10.921,0:01:11.921 lead acid, 0:01:12.081,0:01:13.801 nickel-metal hydrate, 0:01:13.801,0:01:14.851 lithium-manganese 0:01:14.851,0:01:18.000 and lithium-ion polymer[br]batteries as the accessories. 0:01:18.845,0:01:22.068 Interestingly, a young[br]Ghanaian, Lawrence Adjei 0:01:22.068,0:01:26.030 has added to the innovations[br]in the electric bike industry. 0:01:26.030,0:01:29.075 He uses sports laptop[br]batteries, which he purchases 0:01:29.075,0:01:34.430 from scrap yards and computer[br]shops in Accra to make his unique e-bikes. 0:01:34.800,0:01:38.182 He is known to be the first [br]Ghanaian to make electric bicycles 0:01:38.182,0:01:42.000 from sports laptop batteries[br]and he is self-taught. 0:01:45.471,0:01:50.088 I stay close to Lawrence and[br]I happen to be this co-helper. 0:01:50.088,0:01:52.222 This is not my first time riding. 0:01:52.472,0:01:54.460 I've been riding for two years now. 0:01:54.460,0:01:56.463 The experience is different. 0:01:56.621,0:02:00.202 Different. I can't even compare[br]because riding a normal bicycle... 0:02:00.202,0:02:01.370 is full of pain. 0:02:01.370,0:02:05.740 And then you actually admire the [br]kind of kilometers you need to go. 0:02:06.001,0:02:10.339 So this is really different compared[br]to the ones I have ever used. 0:02:10.339,0:02:13.700 This has three gears[br]and then the others don't. 0:02:14.280,0:02:20.543 It has a brake which charges the battery[br]back when applying, the others don't have. 0:02:21.001,0:02:24.537 It has a USB spot which[br]can charge your phone 0:02:24.537,0:02:26.250 or use a USB light. 0:02:26.541,0:02:28.254 Which the others don't have. 0:02:28.811,0:02:32.062 And then it also has a bell,[br]the others didn't have a bell. 0:02:32.962,0:02:36.634 And then the brakes are instant stop. 0:02:36.794,0:02:38.010 They stop instantly. 0:02:38.370,0:02:40.525 Next. Coming to the battery, 0:02:40.525,0:02:42.944 it has a large capacity,[br]which you can even 0:02:43.204,0:02:45.586 give a house a light. 0:02:49.275,0:02:52.640 This is where Mr. Lawrence[br]AJ makes all the inventions. 0:02:52.640,0:02:55.647 This is where the[br]creation of electric bicycles 0:02:55.647,0:02:58.920 made out of dead[br]laptop batteries happens and 0:02:58.920,0:03:01.000 I'm currently here with Mr. Lawrence. 0:03:01.601,0:03:03.656 Take us through [br]the process involved in the 0:03:03.656,0:03:07.000 usage of these batteries [br]to make the electric bicycle. 0:03:07.481,0:03:09.640 So you have the batteries here. 0:03:09.993,0:03:11.986 So, you just crack them like this. 0:03:12.511,0:03:15.121 You sometimes bend it or... 0:03:15.891,0:03:16.891 or use a plier. 0:03:17.247,0:03:18.267 Okay 0:03:21.533,0:03:24.500 You can see that we[br]don't use all the cells. 0:03:24.551,0:03:26.054 This one is here, the bud. 0:03:26.784,0:03:28.870 -Okay[br]-You can't use this one, so 0:03:28.870,0:03:30.063 You find a different one. 0:03:30.654,0:03:31.753 Try another one. 0:03:38.610,0:03:39.639 Same. 0:03:39.639,0:03:42.665 This one is okay. So you take [br]like the motherboard 0:03:42.665,0:03:44.180 - of the battery. So...[br]- Okay 0:03:44.439,0:03:45.439 So taking them off 0:03:46.058,0:03:48.828 [Inaudible] 0:03:54.638,0:03:56.965 Then take the cells out like this. 0:03:57.463,0:03:58.503 Okay 0:04:00.391,0:04:02.780 So in total, how many [br]of these do you need? 0:04:03.001,0:04:04.260 I need a lot, but 0:04:04.260,0:04:05.991 I only have 6 batteries here. 0:04:05.991,0:04:07.001 Okay 0:04:07.001,0:04:12.000 Then you test it with the voltmeter to[br]see whether they have some voltage inside. 0:04:12.001,0:04:15.000 What is the average voltage[br]you need in the batteries? 0:04:15.001,0:04:17.588 I think like 2.5 volts.[br]2.5 volts is fine. 0:04:17.588,0:04:19.131 - Okay[br]- This one is good 0:04:19.131,0:04:20.968 - Okay[br]- So then we come here 0:04:20.968,0:04:22.840 and test with this machine here. 0:04:22.840,0:04:24.759 This one is called Opus. 0:04:24.759,0:04:27.096 This one does the capacity testing. 0:04:27.096,0:04:30.000 - Okay[br]- So you place the cells inside like this. 0:04:30.001,0:04:32.425 So you can see it charging, so... 0:04:32.425,0:04:34.940 It will charge the batteries[br]for like two hours 0:04:34.940,0:04:36.470 - Okay[br]- Only two hours 0:04:36.470,0:04:43.000 After that, the machine will discharge[br]the battery and give you the capacity. 0:04:43.159,0:04:44.970 -Okay[br]-Then we take it off. 0:04:44.970,0:04:48.360 Then we write the capacity on it. 0:04:52.001,0:04:53.951 Comparing the other things too 0:04:53.951,0:04:58.000 It has a Bluetooth device in it, [br]which you can use to program your phone. 0:04:58.270,0:05:02.309 So imagine I'm going on a[br]high speed, you don't like drop 0:05:02.309,0:05:05.000 it on your phone and then[br]it will drop automatically. 0:05:05.001,0:05:07.000 It doesn't matter the acceleration. 0:05:07.001,0:05:10.000 For the other bikes,[br]they don't have reverse. 0:05:10.001,0:05:12.000 You just need to push them back like this. 0:05:12.001,0:05:13.778 But then this one has a reverse. 0:05:13.778,0:05:15.000 So there is no need. 0:05:15.001,0:05:19.000 When the key is on, you just push[br]the button and then you accelerate. 0:05:19.001,0:05:21.919 It doesn't accelerate[br]like you're on a top 0:05:21.931,0:05:27.000 speed, but it's very strong[br]and it takes you back slowly. 0:05:27.250,0:05:31.000 No matter what obstacle,[br]it will take you back slowly. 0:05:31.001,0:05:34.000 I think this is all about. 0:05:34.001,0:05:37.000 For the other bikes,[br]we do have front shocks. 0:05:37.100,0:05:41.800 And then, front shocks, talking[br]about this one, this is filled with air. 0:05:41.800,0:05:43.570 It's different from the other one. 0:05:43.570,0:05:47.000 The other one is a[br]little air, but more of oil. 0:05:47.001,0:05:51.000 But then this one is[br]air, so you stop instantly. 0:05:51.001,0:05:53.000 And you see for the back too. 0:05:53.001,0:05:55.000 It's also different for the back. 0:05:55.150,0:05:57.347 Actually, the other[br]bikes, when you are riding 0:05:57.347,0:06:00.721 and then you pass through a pothole,[br]you feel some pains in your waist. 0:06:00.721,0:06:02.420 But then this one, you don't feel. 0:06:02.420,0:06:05.000 You just go through and then you're okay. 0:06:05.001,0:06:08.165 So anytime you are[br]riding this bike, it makes 0:06:08.177,0:06:11.000 you feel like go more,[br]go more, go more. 0:06:11.150,0:06:14.700 It's really nice to have[br]one of these bikes. 0:06:18.860,0:06:20.625 My name is AJ Lawrence. 0:06:20.650,0:06:23.000 I live in Kaswa in the[br]central region of Ghana. 0:06:23.075,0:06:25.934 At age 11, when Lawrence[br]discovered his talent, 0:06:25.946,0:06:31.000 he acquainted himself with playing with[br]electronic gadgets such as computers. 0:06:31.425,0:06:34.170 A year after his[br]interest in that field grew, 0:06:34.182,0:06:37.000 he picked up the mantle[br]of repairing bicycles. 0:06:37.001,0:06:40.000 Until date, he still[br]repairs a number of bikes. 0:06:40.100,0:06:44.000 So far, Lawrence has made and[br]sold four e-bikes made by himself. 0:06:44.125,0:06:49.810 Current bicycle presents upgraded features[br]from the ones he has made in the past. 0:06:49.810,0:06:51.831 Professor Jay looks[br]forward to contacting 0:06:51.831,0:06:54.220 universities for[br]collaborations and partnerships 0:06:54.250,0:06:59.000 in order to take his innovative[br]ideas to the next level. 0:06:59.001,0:07:04.000 He has dreams of using solar to propel his[br]bikes in future, but needs collaborations 0:07:04.001,0:07:06.927 and partnerships with[br]universities and technical 0:07:06.939,0:07:10.000 institutions to scale up[br]production from prototype 0:07:10.450,0:07:12.000 to commercialization. 0:07:12.150,0:07:15.005 In such partnerships,[br]he seeks to train technical 0:07:15.017,0:07:18.000 students to improve their[br]knowledge on electronics. 0:07:21.900,0:07:23.761 I have a question. 0:07:23.786,0:07:26.767 So this experiment only works[br]when you are using the spot 0:07:26.767,0:07:29.380 or dead laptop batteries or[br]you can use brand new ones. 0:07:29.380,0:07:31.160 You can use brand new ones for sure. 0:07:31.160,0:07:32.190 Okay 0:07:32.190,0:07:33.230 Okay. 0:07:33.230,0:07:36.000 So now on charging the[br]bicycle, how is it charged? 0:07:36.001,0:07:39.184 It's charged with this charger here. 0:07:39.184,0:07:40.952 This one is a custom built charger. 0:07:40.952,0:07:42.540 It's not like the normal charger. 0:07:42.540,0:07:44.980 It will take like maybe 12[br]hours, 6 hours to charge. 0:07:44.980,0:07:46.010 Ok 0:07:46.010,0:07:47.689 This one does around like 3 hours. 0:07:47.689,0:07:49.171 Okay. 0:07:50.801,0:07:52.270 And did you make it yourself?
