The frame concept was actually considered complete and was only to be confirmed with the driver test vehicle. However, a wooden skeleton that has since been used purely as a space model and the test rides with interested parties in the TWIKE 4 gave us clear indications that the entry ergonomics needed to be revised. The side profile was too high, and getting into the model was not always effortless. A renewed investigation showed the possibilities for improvement, but also the resulting consequence: the frame structure had to be touched again.
Under no circumstances was a new solution allowed to become more uncertain or more difficult in the process. The mechanical designers, the designer and the supplier of the exterior components had to sit down together, work out a new design approach and check it for implementation. And in retrospect, this has been perfectly successful.
Not only is entry for people of all sizes and ages more effortless than in any other vehicle we know of. It also opens the cohesive hood upwards exclusively in the turning process and therefore does not take up any parking space to the side. Tendentially heavy components were able to move further down, favoring a low center of gravity for the entire vehicle. In addition, the weight of the components themselves was further reduced. Since the majority of the hood body is located in the upper half of the vehicle, this weight reduction will be beneficial in all conceivable driving maneuvers.
Last but not least, the complete outer skin could be made even more visually pleasing with the overhaul. With the new design, we are now moving on to further optimization of the aerodynamics and integration of the safety zones. As always, we look forward to your feedback!
