WEBVTT 1 00:00:06.000 --> 00:00:10.000 Pedelecs are bicycles equipped with an electric motor. 2 00:00:11.000 --> 00:00:16.000 Unlike an e-bike that has a turning handle like a moped, 3 00:00:16.040 --> 00:00:20.000 the Pedelec’s motor only kicks in once you start pedalling. 4 00:00:20.500 --> 00:00:24.000 The Pedelec just makes pedalling much easier. 5 00:00:26.000 --> 00:00:35.000 This is our roller test bench that helps determine the Pedelec’s power 6 00:00:35.040 --> 00:00:38.000 consumption to find out which components should be more efficient. 7 00:00:38.040 --> 00:00:43.000 We primarily test the batteries to improve them accordingly. 8 00:00:43.500 --> 00:00:47.000 This drive motor simulates the pedalling cadence. 9 00:00:48.000 --> 00:00:52.000 brake motor simulates resistance, e.g. 10 00:00:52.040 --> 00:00:57.500 wind resistance, roll resistance, or gradient resistance. 11 00:00:58.000 --> 00:01:03.000 We enter all these factors into the computer to initiate the simulation. 12 00:01:03.500 --> 00:01:10.000 Then we turn on the Pedelec and make further adjustments. 13 00:01:12.000 --> 00:01:18.000 Now we choose a profile and start the machine. 14 00:01:22.000 --> 00:01:24.000 The white line represents the target speed. 15 00:01:25.000 --> 00:01:28.000 The red line shows the actual speed. 16 00:01:28.500 --> 00:01:33.000 In addition, this current clamp tells us 17 00:01:33.040 --> 00:01:37.040 how much power and voltage we’re currently using. 18 00:01:38.000 --> 00:01:41.000 Based on this, the computer calculates the motor’s effective power, 19 00:01:41.040 --> 00:01:44.000 i.e. how much battery power is currently being used. 20 00:01:44.040 --> 00:01:48.000 And this shows the bicycle’s performance. 21 00:01:49.000 --> 00:01:53.000 Finally, all values are saved and we can calculate 22 00:01:53.040 --> 00:01:56.000 the bike’s actual power consumption. 23 00:02:00.500 --> 00:02:04.000 Presently there are 4 rental stations in Hanover where you can rent a Pedelec. 24 00:02:04.040 --> 00:02:06.000 One of them is located at the university 25 00:02:06.040 --> 00:02:08.500 on Bismarkstraße 2 at the Pedelec-Café. 26 00:02:09.000 --> 00:02:15.000 Before a Pedelec can be rented, the station’s staff 27 00:02:15.040 --> 00:02:18.000 goes through a checklist to make sure everything’s okay in order 28 00:02:18.040 --> 00:02:24.050 to avoid minor accidents. Then you’re good to go. 29 00:02:29.000 --> 00:02:32.000 You don’t have to struggle with inclines or headwinds anymore. 30 00:02:32.040 --> 00:02:38.000 That’s what makes riding a Pedelec so much fun. 31 00:02:40.000 --> 00:02:45.000 It immediately becomes apparent how much less effort you need 32 00:02:45.040 --> 00:02:49.000 when you overtake people on regular bikes. 33 00:02:49.500 --> 00:02:53.000 The demand is enormous. People recognise the advantage 34 00:02:53.040 --> 00:02:55.000 of not having to rely on a car. 35 00:02:55.500 --> 00:02:59.000 And getting around Hanover is much faster on a Pedelec 36 00:02:59.040 --> 00:03:02.000 than by car, tram, or bus.
