Human Power

In order to get a very good feeling for the power necessary to achieve a certain speed with a specific bicycle we recommend to use the Bicycle Speed Calculator provided by Kreuzotter: http://www.kreuzotter.de/english/espeed.htm.

100 up to 200% Human Power

As a rule of thumb one can easily remember:
  • ♦ An average cyclist is able to pedal a constant 100 W.
    ♦ A strong sports-cyclist is able to pedal a constant 200 W at least for a certain time e.g. 1 hour.
    ♦ The worlds best cyclists are able to pedal around 400 W during a race.
    ♦ Two cyclist on a tandem double the power!
    ♦ The SUNDEM® motor has around 400 W rated motor power - equals 4 average cyclists.
