自行車為綠色環保產品，基於環保、休閒的因素，在目前講求樂活的社會中，深受大家喜愛。其中，折疊自行車的特性更是因為技術與環境的關係，成為近年來的熱門商品。為了擁有與創造新顧客群，企業必須瞭解目標市場或是創造新的市場區隔來進行產品線策略，其可以帶來更高的利潤與品牌價值。故本研究使用品質機能展開（quality function deployment, QFD）進行折疊自行車的產品開發、顧客需求分析與產品設計。並且使用層級分析法（analytical hierarchy process, AHP）得到顧客要求品質權重值，以了解不同顧客對某要求品質的重視程度。然後用了集群分析法(cluster analysis）將顧客要求品質權重值分六群，用以發現市場區隔的消費者在要求品質方面有哪些顯著差異，依不同市場區隔擬定不同的策略方案，來滿足各種不同消費者的需求。
　　結果顯示，市場區隔3、4、6與一般認知不同。以市場區隔3「電動型折疊自行車」來看，目前國內知名大廠皆沒有電動型折疊自行車，但結果顯示此市場區隔可以為廠商帶來一定的利潤。以市場區隔4「外觀取向折疊自行車」來看，應設計一款具有吸引力且價格不昂貴的折疊型自行車來滿足重視外觀的消費者，且廠商也可以藉由額外的配件設計，來滿足此市場區隔的額外需求。以市場區隔6「價格與攜帶取向折疊自行車」來看，會有市場區隔重視價格與攜帶性，對功能上的要求不大，故廠商在這方面可以提供價格平易近人且非常好攜帶的折疊型自行車來滿足此市場區隔的需求。另外，研究中也有對不同市場區隔的顧客特性進行探討描述，以做出可供參考的結論與建議。

　　Because of environmental protection and leisure, bicycles become very popular and green products. Especially, the convenient characteristics of folding bicycle make it be the most popular green product. In order to create new customer groups, business must understand the demand of new markets; determine the segmentation and product line strategy that can increase profit.
The thesis applied Quality Function Deployment（QFD）to help product development, product design and customer requirement management of bolding bicycle. Also, used Analytical Hierarchy Process（AHP）to gain the weight of customers’ requirement. Finally, used Cluster Analysis to separate customers into market segment, found different customers’ preferences and came out a useful strategy for the segments to increase customer satisfaction.
　　The result of this thesis showed that segment 3, 4, 6 are different from common cognition. Segment 3 “electrical folding bicycle”, There are no well-known companies providing electrical folding bicycles in Taiwan, but this product line has a great potential to increase the profit of a company. Segment 4 “good-looks folding bicycle”, design and appearance are the most attractive factors to this segmentation, so company can provide folding bicycles which is good looking and not expensive to fulfill this requirement. Segment 6 “Price and convenient folding bicycle”, this segmentation focus on the price and the easy-carrying ability of folding bicycles. Besides, this thesis also found the customer characteristic of segments that can help provide some and suggestions on folding bicycle for bicycle companies.
