The Sichelrad was one of the most unusual German bicycle designs. Presumably influenced by the American Victor Springfork bicycle of the late 1880s, the Anker-Werke company made a front spring fork for their bicycles. This model then became the top of their range.

It certainly is very distinctive. It does make the front end slightly heavier. Like all spring forks and spring frames introduced onto bicycles over the years, I can’t say it particularly improves the suspension of the bike. However, like all unusual innovations fitted to bicycles, it definitely turns an otherwise mundane bicycle into a very interesting conversation piece and collector’s item.

From 1949-1958 the factory in Bielefeld, Germany, built motorcycles with Sachs and JLO engines 98-250cc. In 1952 the Paderborner Maschinenbau AG in Paderborn took over the Anker factory. Subsequently the motorcycles were built in Paderborn and only moped production was continued in Bielefeld for a couple of years.

The BSA Ariel 3 tricycle used the Anker Laura moped engine.
