When designing a bakfiets, it is worth noting the six methods we have for controlling the front end geometry of the bike. Remember that when you select one of these methods, you are choosing to drive the front end geometry by a single pair of dimensions. The other five pairs of dimensions will behave as driven dimensions. You can select almost any of these options and toggle smoothly between a regular bike design and a bakfiets bike design. For example, if we choose the stack and reach method, when we toggle from regular bike to bakfiets, our bakfiets will have the same stack and reach we started with. The one pair of dimensions you'll likely not want to use when toggling between regular bike and bakfiets is the front center distance and head tube length. Your bakfiets will need a much longer front center distance, so this is not a dimension you'll want to hold constant when toggling between these two styles of bike.
