Final answer:
The term 'scus' seems to be a typo or miscommunication. If it means SKUs, then multiple individual SKUs corresponding to each part such as the frame, wheels, tires, etc., are needed to build a youth bike. The exact number of parts, and therefore SKUs, varies depending on the bike's complexity.
Step-by-step explanation:
The question 'How many scus does it take to build a youth bike?' seems to contain a typo or a misunderstanding, as 'scus' is not a recognized term in the context of building bicycles. However, if we consider that 'scus' might be referring to a misinterpretation of a unit used in manufacturing or technology, such as SKUs (Stock Keeping Units), we can provide a clearer answer.
In the context of building a youth bike, SKUs would refer to the different parts inventory kept in stock that are necessary to assemble a bike. To build one youth bike, it typically takes multiple individual components such as the frame, wheels, tires, brakes, gears, seat, handlebars, and potentially additional accessories. Each of these components could have an individual SKU number associated with them. Therefore, the number of SKUs or different parts required for building a youth bike could vary from dozens to potentially over a hundred, depending on the bike's complexity.
However, without the correct terminology or a more specific context, it is difficult to provide a precise number of units (whether they are scus, SKUs, or any other unit) necessary to build a youth bike. If 'scus' is meant to reflect something different entirely, additional context would be needed to give an accurate answer.
