Trek Bicycle Corporation is a bicycle and cycling product manufacturer and distributor under the brand names Trek, Electra Bicycle Company, Bontrager, and Diamant Bikes. The company has previously manufactured bikes under the Gary Fisher, LeMond Racing Cycles, Klein, and Villiger Bikes brand names. With its headquarters in Waterloo, Wisconsin, Trek bicycles are marketed through 1,700 independently owned bicycle shops across North America, subsidiaries in Europe, Asia, South Africa, as well as distributors in 90 countries worldwide.

The brand offers standard and electric bikes, as well as parts and accessories. Their offerings include electric commuter, road, mountain, and hybrid electric bikes, as well as offering standard and custom non-electric bikes.

Trek first started making bicycle frames in 1976. Trek made a total of 805 frames that first year (according to a 2008 article in the New York Times). Two years later they started offering complete bicycles in addition to the bare frames.

Trek domestic bike production figures for late 1980 through 1986 were calculated from Trek’s paper serial number list for this period. The results are presented on the Trek Bike Production by Model, Late 1980 through 1986 page.

In recent years Trek, as has the industry in general, has moved away from steel frames in favor of aluminum and composite materials. However, Trek still offers a steel-framed touring bicycle, the model 520, to meet the needs of their customers who know and prefer the functionality of a steel bike. Over time, Trek has expanded its domain by purchasing other bicycle manufacturers. These include Bontrager, Gary Fisher, Klein and LeMond.
