07.03.2018 / In addition to detailing the frame structure, the hood and window mechanics, securing the connection concept for the trim parts, clarifying long-term availability, etc., the developers are currently working up the so-called BOM (bill of materials), i.e. the list of all individual parts, piece by piece. The BOM is an elementary basis for purchasing but also for the following process of construction up to the later stocking of spare parts, when vehicles have been delivered for a long time and have even served their service for 20 years.


According to a manufacturer-specific standard, a part number has to be assigned, the specification has to be documented, drawings have to be derived, 3D data has to be stored in a kind of digital safe on the server and, of course, the cost of the parts has to be secured. If the part price is higher than the target price, renegotiation with the supplier and, in the negative case, developmental revision of the assembly with a view to a more cost-effective solution is required.


The prospect of the next large series with the TWIKE 6 already helps in some cases to motivate the suppliers to be more accommodating with regard to the purchase price even for the exclusive series of the TWIKE 5. In addition to the creative development work, this part of the negotiation is also exciting, but it is also exhausting. In the argumentation your previous engagement is helpful in any case, we can refer to daring nearly 40 TWIKE pioneers with whom we could lift so far already over a quarter of the total budget of 2 million €.


In addition to consistently continuing and working through the development tasks, it is now precisely this potential that must be further leveraged and the additional 160 pioneers found and inspired for the initial series.
