Pedelec is the abbreviation for "Pedal Electric Cycle". In comparison to other two-wheelers with an electric motor (in general often called "E-Bikes" or „Scooters“), the characteristic of a pedelec is that the electric power only assists the human power instead of replacing it: The current output of the electric motor usually is proportional to the current human power contribution. This means, that a pedelec does not move without pedalling. Moreover there is a speed limit for the electric assistance of the motor: Pedelecs in the sense of European legislation stop the electric motor above a velocity of 25 km/h.

Advantages of Pedelecs

 Compared to other electric two-wheelers, pedelecs have the following advantages:

1. Because of the 25 km/h limit and the absence of any controls to be handled during the ride, a pedelec does not pose any additional challenge to the driver. Because of this, it is acknowledged as a bicycle without the requirements of a motorcycle concerning lincence plates, driving licences, use of bike lanes etc.
2. As far as it can be pedalled without the usage of the motor, you will always get home even with an empty battery.
3.  It requires at least some physical exercise, keeping users healthy (and warm in winter).

Compared to conventional bicycles without an electric motor, the main advantage of a pedelec is by nature more speed for less physical effort. Whilst the potential of higher speed (and thus wider range within the same riding time) in flat regions is limited by the 25-km/h-limit as well as by the air resistance, increasing disproportional to the speed, pedelecs have their most impressive effect on slopes. The other way round, getting the same speed for less effort is particularly attractive for elderly people and employees , who do not want to arrive in their office with sweatpatches.

Disadvantages of Pedelecs

1. Pedelecs of appropriate quality are about twice as expensive as conventional bicycles. This means not only higher direct costs, but also the necessity of better theft protection.
2. Despite a battery technology which has been significantly improved within the last years, a pedelec still needs more care and attention than an ordinary bike, as batteries are to be charged regularly even if not used at all and should be stored in a defined temperature range. Battery lifetime is still limited and replacement batteries represent further costs.
3. Pedelecs are heavier than ordinary bikes
4. If pedelecs replace bicycles for the same rides, there is a reverse effect concerning physical exercise and health.
