00:04:03.001 --> 00:04:04.000 I need a lot. 00:04:04.001 --> 00:04:07.000 But I only have 6 batteries here. 00:04:07.001 --> 00:04:12.000 Then you test it with the voltmeter to see whether they have some voltage inside. 00:04:12.001 --> 00:04:15.000 What is the average voltage you need in the batteries? 00:04:15.001 --> 00:04:17.128 I think like 2.5 volts. 00:04:17.152 --> 00:04:19.152 2.5 volts fine. 00:04:19.153 --> 00:04:20.006 Okay 00:04:20.031 --> 00:04:23.000 So then we come here and test with this machine. 00:04:23.001 --> 00:04:25.000 This one is called Opus. 00:04:25.001 --> 00:04:28.000 This one does the capacity testing. 00:04:28.001 --> 00:04:30.000 So you place the cells inside like this. 00:04:30.001 --> 00:04:31.000 So you can see it charging. 00:04:31.001 --> 00:04:37.000 It will charge the batteries for like 2 hours, maybe 3 hours. 00:04:37.001 --> 00:04:43.000 After that, the machine will discharge the battery and give you the capacity. 00:04:43.001 --> 00:04:45.000 -Okay -Then we take it off. 00:04:45.001 --> 00:04:48.800 Then we write the capacity on it. 00:04:52.001 --> 00:04:56.000 Comparing the other things to, you have a Bluetooth 00:04:56.001 --> 00:04:58.000 device in it which you can use to program your phone. 00:04:58.050 --> 00:05:02.599 So imagine I'm going on a high speed, you can just drop 00:05:02.624 --> 00:05:05.000 it on your phone and then it will drop automatically. 00:05:05.001 --> 00:05:07.000 It doesn't matter the acceleration. 00:05:07.001 --> 00:05:10.000 For the other bikes, they don't have reverse. 00:05:10.001 --> 00:05:12.000 You just need to push them back like this. 00:05:12.001 --> 00:05:14.000 But then this one has a reverse. 00:05:14.001 --> 00:05:15.000 So there is no need. 00:05:15.001 --> 00:05:19.000 When the key is on, you just push the button and then you accelerate. 00:05:19.001 --> 00:05:21.919 It doesn't accelerate like you're on a top 00:05:21.931 --> 00:05:27.000 speed, but it's very strong and it takes you back slowly. 00:05:27.250 --> 00:05:31.000 No matter what obstacle, it will take you back slowly. 00:05:31.001 --> 00:05:34.000 I think this is all about. 00:05:34.001 --> 00:05:37.000 For the other bikes, we do have front shocks. 00:05:37.100 --> 00:05:42.000 And then, front shocks, talking about this one, this is filled with air. 00:05:42.001 --> 00:05:43.000 It's different from the other one. 00:05:43.001 --> 00:05:47.000 The other one is a little air, but more of oil. 00:05:47.001 --> 00:05:51.000 But then this one is air, so you stop instantly. 00:05:51.001 --> 00:05:53.000 And you see for the back too. 00:05:53.001 --> 00:05:55.000 It's also different for the back. 00:05:55.150 --> 00:05:57.084 Actually, the other bikes, when you are riding 00:05:57.096 --> 00:06:01.000 and then you pass through a pothole, you feel some pains in your waist. 00:06:01.001 --> 00:06:02.000 But then this one, you don't feel. 00:06:02.001 --> 00:06:05.000 You just go through and then you're okay. 00:06:05.001 --> 00:06:08.165 So anytime you are riding this bike, it makes 00:06:08.177 --> 00:06:11.000 you feel like go more, go more, go more. 00:06:11.150 --> 00:06:14.700 It's really nice to have one of these bikes. 00:06:18.860 --> 00:06:20.625 My name is AJ Lawrence. 00:06:20.650 --> 00:06:23.000 I live in Kaswa in the central region of Ghana. 00:06:23.075 --> 00:06:25.934 At age 11, when Lawrence discovered his talent, 00:06:25.946 --> 00:06:31.000 he acquainted himself with playing with electronic gadgets such as computers. 00:06:31.425 --> 00:06:34.170 A year after his interest in that field grew, 00:06:34.182 --> 00:06:37.000 he picked up the mantle of repairing bicycles. 00:06:37.001 --> 00:06:40.000 Until date, he still repairs a number of bikes. 00:06:40.100 --> 00:06:44.000 So far, Lawrence has made and sold four e-bikes made by himself. 00:06:44.125 --> 00:06:50.000 Current bicycle presents upgraded features from the ones he has made in the past. 00:06:50.001 --> 00:06:51.831 Professor Jay looks forward to contacting 00:06:51.843 --> 00:06:54.000 universities for collaborations and partnerships 00:06:54.250 --> 00:06:59.000 in order to take his innovative ideas to the next level. 00:06:59.001 --> 00:07:04.000 He has dreams of using solar to propel his bikes in future, but needs collaborations 00:07:04.001 --> 00:07:06.927 and partnerships with universities and technical 00:07:06.939 --> 00:07:10.000 institutions to scale up production from prototype 00:07:10.450 --> 00:07:12.000 to commercialization. 00:07:12.150 --> 00:07:15.005 In such partnerships, he seeks to train technical 00:07:15.017 --> 00:07:18.000 students to improve their knowledge on electronics. 00:07:21.900 --> 00:07:23.761 I have a question. 00:07:23.786 --> 00:07:28.117 So this experiment only works when you are using the spot 00:07:28.142 --> 00:07:30.000 or dead laptop batteries or you can use brand new ones. 00:07:30.001 --> 00:07:31.000 You can use brand new ones for sure. 00:07:31.001 --> 00:07:32.000 Okay. 00:07:32.001 --> 00:07:33.000 Okay. 00:07:33.001 --> 00:07:36.000 So now on charging the bicycle, how is it charged?
