Karl Drais / 卡尔·德莱斯

Karl Drais is the German baron and inventor who enters the wiki through No.199 自行车 200年 as the source’s starting point for modern bicycle history. The episode presents his 1817 two-wheeled running machine as a response to horse, oat, and transport stress after climate disruption made horse-powered movement more expensive.

His invention matters less as a finished bicycle than as the first product step in Bicycle Product Evolution. It had no pedals, chain, or pneumatic tires, but it made a seated, steerable, two-wheeled personal vehicle imaginable before later makers such as Pierre Michaux / 皮埃尔·米肖, Pierre Lallement / 皮埃尔·拉勒芒, and John Kemp Starley / 约翰·坎普·斯塔利 stabilized the form.
