Introducing the worlds safest E-bike: ULTRABIKE

Blindspot Assist System

The Calamus One is equipped with Blindspot Assist System that constantly scan for approaching vehicles outside your field of vision. If you happen to turn or change lanes while a vehicle approaches in your blindspot, your handle-bar will vibrate to warn you.

Turn indicators in handle-bars

The handlebar edges house LED safety white lights which also double as turn indicators at the push of a button. The turn indicators activate in the form of a rhythmic circular ring to give it a beautiful touch.

Fingerprint unlock

The bike also has an ultra-fast biometric scanner for locking, unlocking and rider profile recognition. The scanner is a capacitive fingerprint scanner that is located just below the screen on the handlebar.

Quick charging

The bike has the ability to charge extremely quickly - 50% or 30 km in 75 minutes and 80% in 2 hours and 100% in 3 hours. This is achieved by using a special high current output charger but without affecting the overall battery life.

Worldwide Tracking

A global GSM chip in conjunction with the bike's GPS system, allows you to locate your bike in case it was stolen or misplaced. The geo-fencing feature lets you set a virtual safe zone for your bike on the map. If your bike ever wanders out of this safe zone, an alarm will be triggered to your mobile phone.

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!
