preface
Dear customers and cycling fans!
From now on, your cycling experience will be enriched by a whole new dimension.
Thanks to our Austrian invention, previously inaccessible trails and destinations
are reachable at the mere touch of a button - and all within a healthy pulse range!
So now there’s nothing to stop you getting out for a leisurely, yet tness-enhancing,
bicycle ride with your partner or group of friends.
A bicycle should remain a wonderful piece of sport equipment. The functions and
handling characteristics of your bicycle do not change by the system. Because of the
small extra weight of less than 2 kilograms you can use the bicycle further without
reservation. From the outside you can only see the small button on the handlebars,
nothing else.
Please read these operating instructions carefully and keep the booklet for future
reference!
…RIDE ON(E)!
Your vivax assist Team
e-Drive for bicycles
