Is “by bike” grammatically correct?

The phrase “by bike” is perfectly acceptable and grammatically correct English. It’s a common and widely understood way to describe the method of transportation. This usage follows a standard pattern of prepositional phrases used to specify the means of travel. Phrases like “by car,” “by train,” “by bus,” and “by plane” all function similarly. The preposition “by” introduces a phrase that clarifies how someone or something is travelling, and “bike” acts as the noun denoting the specific mode of transport. This construct is perfectly natural and unambiguous in English.
