The model year convention is the most explicit manifestation of N+1 Thought there is. What better way to sell another bicycle to someone who already has one than to use a date to signal that the latest model year is somehow better than the one the owner already has?
The retailer or brand is making a large investment in a range of models, colors, categories and sizes and hoping that the right person is going to walk in the door within the next twelve months and make a purchase.
The problem is that when the price point selection is broadened, the consumer is overwhelmed with too much choice. A good example of this is the Specialized Diverge gravel bike.
What drives the bicycle industry to repeatedly produce more bicycles and e-bikes each year than the market can absorb? Sunk costs. Economies of scale. Ride it out the door. A bike for every price. Model year.
N + 1 is embarrassingly out of touch. It sounds like the Schafer beer commercial from the 1970s that went “Schafer is the one beer to have when you are having more than one.”
