Biography
He was born in Amsterdam to Pieter Casper Dikkentman, a carpenter, and Sophia Diederica Boekstal. After finishing school he trained as mechanical engineer. He began competing in cycling at the age 16 and specialized in sprint. He was noticed by Jan Mulder, who made him a member of his quint, a type of tandem bicycle ridden by a team of five cyclists. In this discipline Dikkentman won a world title in 1898, and set a new world record in 1899. Around that time he became professionally involved in motor-paced racing. This event was difficult for him, as he had 10 crashed during his career as well as a strong rivalry with the German cyclist Thaddäus Robl; this rivalry, however, made him famous in Germany. Especially difficult was for him the 1904 season when he had a long recovery after being hit by a pacer. Nevertheless, he won three medals at the UCI Motor-paced World Championships, in 1901, 1903 and 1905, including a gold medal in 1903, as well as five European medals. After these successes, Dikkentman, who was a self-managing professional cyclist, became a wealthy man. Yet, for many years he kept a strict daily routine of training and diet. He also followed all technical developments in the design of bicycles and pacing motorcycles. However, his career declined in the late 1900s due to the lack of a good pacer, and he eventually retired in 1913. Dikkentman competed all around the world, including Japan and Australia. On 27 February 1908 he married Lilian Brasker, an Australian. The couple had a daughter, Edna Victoria, and divorced on 11 July 1917. On 14 March 1918 he married again, to Emilie Agnes Minna Zöphel, a German. They had one son and three daughters. While working at his bicycle shop, Dikkentman could not stand the retirement and returned to cycling in the 1920s, finishing in second-third place in the national motor-paced championships in 1921–1923. In 1927, he won a race in Amsterdam in a record time. He retired from active cycling after a race in Szczecin, Poland, on 28 October 1928, aged 49. He continued competing as a pacer, but without much success. In his late years he ran a bicycle shop in his native Amsterdam, where he died in 1950.
