The Ultra features the best-in-class security. Lock and unlock your bike with an ultra-smooth fingerprint scanner, track your bike’s location through our mobile app and rest easy as our anti-theft fasteners make it impossible for petty thieves to steal any part of your Ultra.

But what if a thief wants to steal your Ultra? Let’s play it out.

TLDR: It’s impossible.

First Attempt: Some thief tries to start your bike.

Performance, Unmatched

Power meets efficiency.

Top of the Line

The Calamus Ultra-drive motor is an ultra quick and responsive motor with a combination of cadence and torque sensors for a smooth and natural ride experience.

Natural & Advanced

The Ultra responds naturally to cues from the rider – even the really subtle ones. When the electric motor provides assistance right when you need it, you’ll feel like the bike is plugged into your intuitions.

Comfort First

The Ultra uses an Internal Geared Hub that intelligently maintains a constant cadence by varying the gear ratio when needed. This ensures that the rider is always comfortable and focussed on his surroundings.

Built For The UK

We studied British roads and weather when we built this bike.The touchscreen is weather-proof, the wiring is 100% internal and the tyres are puncture-resistant. Rain or not, The Ultra is always road ready.

Maximum Comfort

Calamus offers auto gear shifts based on real-time riding patterns. The Ultra is made with monoshock suspension – this allows for superior navigation and flawless ride stability.

Battery & Charging

Charge like a phone

The battery is detachable using a special key and can be charged inside your home using any normal plug point.

Ultra-Fast Charging

A 3-hour long brainstorming session at work and your battery is 100% charged. Now that’s faster turn-around than most of your coworkers.

Noise Free Ride

No lubrication. No maintenance. No noise.

Robust, Durable and Light

We used aircraft-grade aluminum to build the bike, and wielded it together in the most advanced way possible – with inert titanium gas.
