The company "Hercules" was founded in 1886 by Carl Marschütz as Velozipedfabrik Carl Marschütz & Co. and produced bicycles in the early years until 1928. It was not until 1928 that the production of motorcycles with an engine capacity of less than 200 cm³ became profitable again. All engines of the Hercules two-wheelers were made by Fichtel & Sachs.
Are your handlebars stiff or do they lock easily? Then worn bearings may be the cause. These broken bearings represent a significant safety risk on your vehicle. Therefore, they should be checked regularly and replaced if necessary.
Your suitable replacement part is just a click away!
