The scooters are at the beginning of their career. They had a lot more technical problems than the bikes. Generally, though, the technology has improved.
Although the scooters had a lot of technical problems, they were still doing better than the bikes did in the Test 1994/95. This shows that the technology has generally improved.
On a scooter, however, the demand for motor performance is even higher than on a bike since there is no pedal assistance from the rider as there is on a pedelec or can be on an e-bike if necessary.
For price reasons all scooters in the test use lead-acid batteries, except for the Heinzmann “electric surfer 805” which is equipped with NiCd batteries. This is why it is 400 Euros more expensive than the “electric surfer 803” with lead batteries. But it is worth the investment if one wants to be sure that the scooter will still be alive once the winter is over. Lead-acid batteries tend to loose performance when the wheather gets gold and they are not kept in a heated place.
The test riders noticed a big difference in how people reacted to the scooters and to the bikes when they saw them riding through the city. Older people did get excited for the bikes but still––generally it was better not to tell that they had electric assistance. In contrast to that, the scooters caused spontaneous enthusiasm among all age groups. People wanted to try, some even to buy them. Image work is definitely easier here.
