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.
