Seizing the Initiative - the Story of an Innovation 


VELOGICAL engineering GmbH based in Cologne (Germany) is dedicated to development and distribution of high efficiency special products to address as yet unsolved technical problems in cycling taking concepts to its logical conclusion without compromise.
When it comes to cycling, VELOGICAL combines personal passion with the renowned cycling heritage of Cologne industrial region, with its flagship “Six Day Race” and “Tour of Cologne”: Germany’s oldest cycle road race. 

Cologne has also been in the forefront of many aspects of energy and its transmission, not least because the world-famous Otto engine, still well known today, was developed here from 1876 onwards.

In 2012 VELOGICAL developed the extremely free-running ‘Cologne cyclesport dynamo’ under the name Compact-Dynamo. 

In 2013 VELOGICAL added the development of the world´s lightest E-Bike Motor VELOSPEEDER. 

In 2020 VELOGICAL develops the UNIVERSAL POWER SOURCE for LED bicycle lighting and USB devices.


VELOGICAL co-founder Dipl. Ing. Peter Frieden is by profession a developer of wind energy installations, in particular the wind certified turbine Easywind 6 for off-grid energy supply. These have earned the description "stormproof" because they can carry on producing power, unrestricted, even in a hurricane. Before that Peter Frieden directed the vacuum pump development department at Oerlikon Leybold Vacuum. His product developments, protected by numerous patent applications, have been successfully applied worldwide and are outstanding in both their high efficiency and in their reliability and low maintenance.
