I happily commute by bike year round in Chicago, as do many other thousands of people that live in the city. It gets into the 90&#x27;s in the summer, and well below freezing in the winter.<p>If it&#x27;s hot I pack my work clothes and change (and shower if needed) at work.<p>If it&#x27;s cold I dress warmly. It&#x27;s amazing how quickly you warm up when pedaling more than a few miles.<p>If it&#x27;s raining I wear a rain jacket, and the fenders on my bike keeps water from splashing up on me.<p>So no, weather is not an automatic fail. It&#x27;s just a mindset change if you&#x27;re used to be in the enclosed bubble that car provides.
