• April 2017

    Contact was made between Eurocircuits and Velomo at the SPEZI special bike show in Germersheim- Germany.

    The initial idea was to rebuilt the eC-velo Challenger

    •  more headroom for taller people
    •  adding the option of carrying a child or extra luggage in the back
    •  increase the stability by making it a 4-wheeler iso a trike.

    Steffen Schönfelder from Velomo had already experience with 4-wheelers, and so the cooperation started.

  • eC-velomo-tion (2018)

    This resulted in a first concept drawing in November 2017

    A prototype, well to be honest two of them were built in Spring 2018 and presented at SPEZI 2018 

    Honestly, the reaction of visitors during the SPEZI show was not very encouraging.  It wasn’t easy to convince trike-fans of the quad-concept.

    Back to the drawing table.

  • Quadvelo (2019)

    The new challenge was to develop an e-assisted HPV that would appeal to a larger public for daily commuting, urban traffic, shopping and family excursions.

    Chassis

    Developed by Steffen Schönfelder from Velomo during the winter 2018-2019. It is a quad-chassis with suspension on all 4 wheels

    Design

    The CAD design was made by Sass Tivadar Viktor from DesignDonum Studio in Budapest.

    We started the design all over again but this time, not based on our experience with the eCvelo Challenger.  It was a much longer than expected exercise with lots of iterations.

    Here are some of the idea’s that passed by :

    November 2018 – we are getting closer – CAD drawings of the structure are proposed.

    Comments are given:

    And finally we agreed about a concept

    Building the prototype (April 2019)

    We want to present a mock-up of our concept to the public by the end of April at the SPEZI special bike show in Germersheim on April 27 and 28.

    On April 15 Steffen arrived with the chassis in Hungary and the rest of the parts are prepared in the Eurocircuits workshop in Eger.

    There is still a lot of work to do and only a few days left.

    Come and see our quadvelo in  Germersheim – in the outside area before Hall 1
