稍微在此回覆anky2002 的話。你說焊接很簡單? 那我問你鋁材有分幾種? 不同種鋁材的焊接方式有什麼不同? 況且除了鋁材之外還有一大堆的材質可以講，這個基礎搞不懂，少在那裡說焊接有多簡單。
而回應開版的autumnshe (秋她)，我找了篇文章，叫做「Where was my bike made?」，幫你翻譯GIANT 的部分就好，請好好閱之。

巨大 - 你可能連自己騎過巨大製的腳踏車都不知道! 巨大可說是全世界規模最大的腳踏車生產者，工廠遍跡台灣，中國和歐洲。這個1972 年起家的台灣公司，生產自家的單車 ── 包括碳纖維車架單車，這在自行車產業中是相當特殊的(換言之，多數的廠牌都是利用其他的廠商像是Adavanced 或 Martec 來生產他們的碳纖車架)。
除了製造自家的腳踏車，巨大也製造了，或是說已經製造了許多其他大廠的腳踏車，包括Trek、Specialized、Schwinn 和 Bianchi。巨大在自行車產業裡老練跟高效率的製造技術，替們贏得了相當好的聲譽。
最後我要提及的一點是巨大擁有穗高百分之三十的股權，穗高是一個重要的台灣單車產業供應商，其供應的廠商相當多，其中一個就是Bianchi。
巨大也同樣也是T-Mobile 職業車隊的贊助商。
Giant - You may have ridden a bicycle made by Giant without knowing it! Giant is the world's largest bicycle manufacturer with factories in Taiwan, China, and Europe. Giant, a Taiwanese company started in 1972, manufacturers their own bikes - including the carbon bikes, which is unique in the industry (i.e., most other brands utilize other manufacturers such as Advanced or Martec).
In addition to making their own bikes, Giant also makes, or has made, bikes for many other prominent brands, including Trek, Specialized, Schwinn, and Bianchi. Giant's claim to fame is that they have the most sophisticated and efficient manufacturing facilities in the bicycle industry.
A bit of trivia is that Giant owns 30% of Hodaka, a key Taiwanese supplier for many brands such as Bianchi.5
Giant also sponsors the T-Mobile professional cycling team.

原文的網址我貼在這，Where was my bike made?，這位文章的作者，在開頭會講得非常明確。
所以請兩位，或是任何對台灣單車產業能力有懷疑的人，請好好看完這篇，然後請多看書，不要沒事就來嘴砲
，打這個很累的...
