Testimonials

As an early adopter I wanted to be a part of this amazing creation. The Ultra Bike struck me as not only a technological wonder but also a work of art. Compare this to almost any other electric bike and the choice is clear. No other bike I know has so many features at such a price

The Calamus crowdfunding campaign popped up just when I was looking for an e-bike to settle in a big city in Germany. The GPS feature immediately seduced me as I am always busy finding my way in this new city. My choice was definitely made to join the Ultra Army when I saw the fine design of the bikes, as well as the reliability of the material used (Nexus, Bafang, etc) and the dynamic Calamus team!
