DESCRIPTION:
CFA is a system designed to take full advantage of the electric propulsion. This
means in other words, not having to stick to the geometric rules of the thermic
bikes.
In general terms, a thermic bike frame has to be structural by itself. All elements
are hooked to it, and it is subject to a great deal of weight, tensions and constant
vibrations. As opposed, the Dragonfly frame is not structural by itself. Like the hu-
man body, in which the bones wouldn’t stay in place if they weren’t tightened by
the muscles, all the surrounding elements participate structurally adding strength
where it is requested. This concept, together with the fact that the number of ele-
ments is much less, quite lighter and free of vibrations, allow a great deal of ben-
efits. These are some of them:

• General reduction of tubular frame weight and dimensions.
• Better distribution of the suspended mass and better placement of the center
of gravity that has a direct impact on stability, balance and weight sensation.
