The look and design language of the Calamus Ultra are inspired by the features and posture of the black panther. With the aim of designing the bicycle to be as user-friendly as possible, the frame geometry, cycling position, safety and connectivity have been carefully balanced. This gives the bike a customised look with sleek, unbroken bodywork contours. The matt black paintwork is automotive quality, and the leather upholstery on the saddle make the e-bike predestined for a strong presence on the road.
