The Calamus One represents a giant leap for e-bike technology. So much, that it creates a whole new class of e-bike – the ultrabike. Powered by Ultra-drive mid-motors from Bafang and driven by carbon belts from Gates, these bikes are ultra-responsive. They’re also ultra-efficient. The Calamus One gives you upto 70kms of range on a single charge, has a detachable battery and quick-charge capabilities. With an integrated weather-proof computer and navigation touchscreen, the One is the only e-bike to offer integrated support for android apps, rider profiles and real-time self-diagnosis.
