This uniquely beautiful piece of Danish design comes from Sogreni Bicycles in Copenhagen. Sogreni was founded in 1981 and specialises in custom bicycles and accessories. The flat brass disc not only pleases the eye in the most ornate way, but plays a crisp, clear note when struck, and tinkles gently over rough roads and kerbs otherwise. More than an ornament, this bell is an ode to joy on my handlebars.
