Highlights
Dropout with speed sensor
To continue the design language and system integration down to the smallest detail, Centurion has integrated the speed sensor of the e-bike into the dropout. Its counterpart sits inconspicuously on the rear brake disk mount. This ensures constant and trouble-free operation.
User Indicator
All important features and access points on the bike are illustrated using an easy-to-understand and self-explanatory guidance system.
Easy Charge
Charging made easy! The charging socket integrated into the top tube of our CENTURION e-bikes is convenient and easy to reach. With a magnetic cover, it is protected against dirt and weather influences, effectively preventing noise on uneven terrain. In addition to its practical added value, our cover is also a real eye-catcher.
Intuitive locking mechanism
Safety and ease of use were the top priorities in the development of our fiberglass-reinforced CENTURION battery cover. It can be removed in a few simple steps so that the battery can be replaced or charged externally. Security screws protect against unauthorized access.
