Diamant is a bicycle brand based in Chemnitz, Germany and originally manufactured by Elite-Diamantwerk (Elite Diamond Works),[1] which was founded in 1882 by Frederick and William Nevoigt to produce knitting machines.[2] They manufactured their first bicycle in 1895.[2] The brand name was acquired by Trek Bicycle Corporation in 2002.[2][3] By the time Diamant ceased production in Germany, its plant was the oldest existing bicycle factory in Germany.[4]
