If people ask us to promote their crowdfunding campaign, we usually do. It’s not an electric motorcycle this time but a whole new class of e-bike – the ultrabike. “The Calamus One represents a giant leap for e-bike technology. 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.” say Nilesh Bothra and Huzaifa Hararwala, Co-founders of Calamus Bikes.


The Calamus One gives you up to 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.
It’s also the first bike equipped with ultrasonic sensors that scan your blind-spots, and handle-grips that vibrate to warn you about approaching vehicles. Utra-bike frames are custom-casted unibodies with 100% internal cabling. This gives the One a bespoke look, with sleek unbroken body contours. Add to this, the premium automotive-grade paint job, and you’ve got an all-round masterpiece with elite road presence.
