Climb in once, please, and check the seat position. Can the hood be opened and closed from the outside by a 5-percentile woman with a height of just under 1.53 m? Does a 95-percentile man not bump his head on the tailgate even at over 1.86 m? Can they both find a seating position in which they can ergonomically reach all the controls and optimally look out of all the glazing?

All these questions have already been taken as a basis for the design and will have to be checked several times during the transition to series production. All the adjustments leading up to series production are therefore a constant balancing act, but one that the development team is mastering with increasing precision and which represents a major quality in the project.

The difference to conventional vehicles is not only the specific ergonomics of the TWIKE due to the pedaling. It is also based on the ergonomic conditions from assembly and subsequent service processes. The BIW (body in white), which is the core of the vehicle, should not be touched during servicing.

The connection of all components, especially the attachment points of all moving parts (chassis, hinges, hood dampers) must also be sufficiently secured to avoid unnecessary costly grinding. The preparatory work for the last development loop of the BIW for the time being was readjusted and checked again. The result of this loop will be the set of drawings for a body-in-white that is suitable for assembly, as light as possible and optimized for crashes. The production method selected is suitable for small series production and will allow the first samples for the driver test vehicle to be produced once the loop has been completed.
